Message from the Conference Chairman

"Power Electronics for Sustainable Growth"
The EPE Conference in Trondheim is the seventh of the series. Even after
the success of Brussels, Grenoble, Aachen, Florence, Brighton and Sevilla,
this EPE conference will offer you more. A record number of synopses have
been received (more than 950), where the increase from industry is
especially significant and has encouraged us to work very hard in
organising numerous new activities and events. These will give each EPE
conference participant the feeling of being the right person in the right
place. We have also accepted a record number of papers, 733. I am proud to
present this detailed programme for what promises to be a highly-successful
Think of the motto: "Power Electronics for Sustainable Growth". These are
no empty words. This is really what we are aiming at. The technical
programme is full of results directed towards that goal: energy savings,
rational and safe use of energy, new energy sources, renewable energy
systems, EMC, electric and hybrid vehicles, locomotives to mention only a
few of the obvious topics.
The opening and keynote sessions will be newsworthy. Mr Odd H. Hoelsæter,
president & CEO of Statnett will explain his view on the evolution of
energy supplies in Europe. Norway is the second-largest oil exporting
country in the world (only after Saudi Arabia): In our sector, three
newHVDC connections will be built between Norway and the continent. This
will be a huge investment that surely will have important consequences on
our future.
If you turn to page 22, you can see other topics that will be presented:
Integration of power components, what will change in our daily work? New
areas of applications for power electronics: you will be challenged by the
authors. The electric vehicle; a silent revolution, however an exploding
technology. But this was not enough!
We wanted more from this conference, so, we are organising a competition.
The topic? To write an essay on either "How to Teach Power Electronics for
Sustainable Growth" or "How to Develop New Power Electronics Products to
Promote Sustainable Growth". The prize? NOK 6.666 and a publication in the
EPE Journal. More details are given on page 9, so gather your best ideas.
Since we are organising this competition, Gro Harlem Brundland, our former
Prime Minister, decided to patronize the Conference.       Gro Harlem Brundland
has been head of the World Commission on Environment and Development and
she hopes that our initiative will spread and open new horizons. In the
UN-report "Our Common Future" it is strongly recommended that the ideas
agreed on in the report should be taught in universities all over the
world. Please send the information about the competition to your power
electronics colleagues, especially the younger ones, all over the world.
You might influence the future!
Before the conference, there will be 11 tutorials where all the new, hot
topics will be taught. Nine will be on the NTNU campus on 6 and 7
September. Those who register will get the written documentation from all
the tutorials and will be allowed to move from one tutorial to another. We
are most enthusiastic about the two tutorials on "High power Motor Drives"
and "UPSs" which will start by touring the Troll Gas Terminal at Kollsnes
close to Bergen and continue on the newest coastal express ship (built in
1996). These tutorials will be combined with a cruise of the west coast of
Norway and the ship arrives in Trondheim on Monday morning 8 Sept. a few
hours before the conference starts!
Do you want to hear more? There is a lot to say:
The exhibition will be greatly extended. We expect more than 50 exhibitors
(there is room for 100 and we will work hard to get 100). The area for the
exhibition will be much more integrated in the conference than before, with
coffee-serving included in the same area. For the first time, there will be
several product presentations by exhibitors; these will be presented before
an informal meal on Sunday 7 September in the evening, which is combined
with the opening of the exhibition in the evening.
Further, a lot of Discussion Sessions will be organisedat at the end of the
Dialogue Sessions. The new developments in power switches will be throughly
discussed and include themes like: "Application Specific Power Modules",
"The Relationship Between Product Developers and Device Manufacturers",
"High Power Integration", "Smart Power - in various applications", "Impacts
of Integration" and "GTOs versus IGBTs".
After the conference, on Thursday 11 September there will be three
Post-Conference Technical Visits.
1) A typical Norwegian hydropower plant with the generators inside the
mountain. The station is within the city limits of Trondheim (!) and is
owned by Trondheim Power Utility.
2) Siemens power electronics factory and a converter station feeding the 16
2/3 Hz for the Norwegian State Railways.
3) ADtranz charter train to the Stømmen factory close to Oslo. We will
learn about the new tilting trains that the Norwegian State Railways has
ordered. At the factory there will be a press conference where a new train
will be presented. The attraction to get the press there will be increased
by our presence. ADtranz will provide buses for a one hour drive to Oslo
So, those who start at Kollsnes close to Bergen and return from Oslo after
the train trip across mountain plateaus and glaciated valleys must sign up
fast. First come, first served. There is a special offer from SAS for the
We have worked hard. But with the expected success, it is a pleasure for us
to welcome you to the EPE '97 conference in Trondheim. At the end I will
like to mention how enthusiastic ABB and other Norwegian and Danish
companies have generously sponsored the conference, so the fee to
participate is the same as in Seville in 1995! The companies are listed in
the provisional programme, and you will learn more from those companies at
the conference and by looking at our WWW

The city of Trondheim

Trondheim was founded by King Olav Tryggvason in 997 A.D. It was the
country's first capital city (until 1217). Trondheim is located by one of
the largest fjords of Norway with the salmon river Nidelven running through
its centre.

Today the city has close to 150000 inhabitants and its total area is 342
square km. The city is an administration, business and technology centre in
a rich agricultural area surrounding the Trondheim fjord. It is a
university city and has Norway's most advanced research community in
science and technology.

During the whole millenium year of 1997, there will be numerous special
events such as The World Ski Championships in February/March, and the
combined 60th birthday celebration of our King and Queen in June, where
royalty from most of the European royal families will attend.

A map of the city is enclosed. References to places shown on the map are
put in the text. One cm on this map is about 140 m.

Normally the weather is pleasant in Trondheim in September. The
temperature may vary between 10-15 degrees C. Rainy days may occur, and we
recommend appropriate shoes and clothing, since some events in the social
programme will take place outdoors.


There are frequent domestic flights between Trondheim and the international
airports in Oslo, Bergen and Stavanger. Flying time between Oslo and
Trondheim is 45 minutes. There are approximately 27 departures from Oslo to
Trondheim daily. There are two daily direct flights between Copenhagen and

SAS (Scandinavian Airlines Systems) is the official carrier of the
congress. Please state the reference number "NO 9701" when you make your
flight reservation at a SAS travel agency, and you will obtain a discount

Travelling by train within Norway gives an excellent opportunity for
sightseeing, and Norwegian trains are of a high standard. The train
journey over the mountains from Oslo to Trondheim takes approximately 7
hours. There are four departures from Oslo to Trondheim daily.

An interesting alternative is to travel by coastal express boat from Bergen
to Trondheim, a journey of approximately 30 hours along the rugged
Norwegian coastline (see pre-conference tours). Your travel agent, or any
SAS travel agency, can supply you with full details on travel to Trondheim.
An APEX air ticket allows transfer to one city in a country, for instance
Bergen, and return from another city in the same country, for instance
Trondheim or Oslo.


The Conference Secretariat has made reservations at several good hotels
within various price categories. All hotels are situated in the city centre
of Trondheim and within approximately 15 minutes walk from the conference

The number of rooms within each category is limited. For reservations,
please fill in the necesssary information on the registration form. The
Royal Garden Hotel is probably the best hotel, it also offers the largest
number of rooms and the largest conference discount.

Rooms will be allocated on a first come, first served basis. We therefore
strongly recommend you to register as early as possible. Reservations have
been made for the conference period. If you would like to extend your
reservation we will do our best to help you. Please note: The registration
deadline for hotel reservations is 1 JULY 1997. After this date we are
only able to confirm hotel accommodation on an availability basis due to
the special situation in Trondheim with the millennium celebrations. We
therefore strongly recommend you to register as early as possible. Please
note that we cannot guarantee hotel accommodation after this deadline.

Reservations must be guaranteed by a credit card. In case of no show etc.
without prior notice to the Secretariat, you will be charged for one night.
Further information will be enclosed with the letter of confirmation of the

During the EPE'97 Conference, a commercial exhibition will be organised.
This is a unique opportunity to see and/or show products and have prolonged
discussions with fellow specialists in the field of Power Electronics and

The aim of the exhibition is to promote technical discussions and business
contacts between specialists in the field. The exhibition will be ideally
situated in the middle of the Conference site, where the coffee will be
served during the breaks and the afternoons. On Sunday 7 September evening,
there will be an informal meal, special products presentations followed by
the official opening of the exhibition.

This year, next to the regular topics, special attention will be devoted to
components and simulation packages. General discussion sessions on these
topics will be organised.

We expect that over 50 compagnies (there is room for more than 100) will
show their products at the exhibition. At the printing deadline of this
programme, dSpace, Analogy, Grundfoss, Hitachi, Elis Elektro, Mitsubishi
Electric, Eldre, Sheco, Powerbox, Tellus EMI already signed up for a booth.

The exhibition set with all practical information is available from the EPE

Exhibitors presentations: Sunday 7 September, 17.00-20.00. Buses will leave
from the tutorial site to Nidarøhallen at 17.00. The final programme will
be available on site.

Related to the moto of the Conference, an essay competition is organised.
The theme to be discussed in the essay will be: "Teaching power electronics
and making new power electronics products to promote sustainable growth".

The best essay will be awarded a NOK 6.666 (approx. US$ 1.000) prize
offered by EFI and will be published in the EPE Journal.

Competition rules

The theme to be discussed in the essay is: "Teaching power electronics and
making new power electronics products to promote sustainable growth". The
final title of the essay is left to the author. The essay will explain how
power electronics in its various aspects can contribute to a sustainable
development worldwide. All aspects may be discussed: technical,
economical, social, environmental, historical, etcŠ

The essay will be judged on the broadness of the documentation, the
originality and realism of the proposed actions.

The essay will be 3000 to 5000 words long. Figures and graphs are to be
put in addition. The essay will end with a list of used references.

The essay will be sent to the EPE Association secretariat in four (4)
copies, three (3) of them being anonymous, and reach before 1 August 1997,
17.00. No delay will be accepted.

The prize will be awarded during the Conference Banquet.

Tourist information Norway

( and

Norway is a unique and exotic destination. Norway can offer you a wide
range of activities and give you an experience you'll always remember. Its
nature has no match. Majestic fjords, a 2,650 km of coastline, mighty
mountains, glaciers, forests, valleys, rivers and lakes.

You can experience some of this in combination with the conference stay or
the pre and post conference tours. Let us recommend a few possibilities:

- a stay in Bergen, including the one day trip "Norway in a nutshell"
- a stay in Oslo, visiting the most popular attractions of the capital city
- an extended stay in Trondheim and the area around.
Røros is a very nice
place to visit (see accompanying persons programme and pre conference tour)
- a tour with the Coastal Express, Hurtigruten: the presented
pre-conference tour from Bergen, or a tour from Trondheim further south to
Bergen or north to Lofoten or all the way to Kirkenes

Norway in a nutshell (
This unique and popular day-excursion takes you through some of the most
magnificent scenery to be found on the west coast of Norway. You leave
Bergen by train in the morning, along the beautiful Sørfjorden to the town
of Voss. From there, you start to climb to the great mountain plateau which
separates the western fjords from East Norway. In Myrdal, you change trains
and then go down the many sharp curves on the famous Flåm Railway which has
a reputation for one of the most spectacular train rides in the world. You
will pass by lofty, snow-capped mountains, thundering waterfalls and
peaceful green meadows on your way to the valley below. After a lunch stop
in Flåm, the trip continues by boat on the Aurlandfjord and Nærøyfjord, one
of the narrowest fjords in Western Norway. From the town of Gudvangen you
will go on by bus to Voss where there is a train waiting for you to take
you back to Bergen. Departure Bergen at 8.50 (return 18.50) and 10.20
(return 20.20). Price: NOK 470

The costal express - Hurtigruten (
The World's Most Beautiful Voyage is a voyage like no other. Nothing can
compare with it. Nothing about this journey will resemble anything you have
ever experienced before. A ticket for the Coastal Express is a ticket to
the theatre, an 11-day drama, from Bergen to Kirkenes and back, in which
new acts constantly unfold all around you. The World's Most Beautiful
Voyage offers a unique combination of peace of mind, comfort, and service
on board, coupled with constantly renewed impressions of the scenery
through which you sail and the harbours you visit. You will witness tender
goodbyes on the quayside next to forklifts loaded with cargo. See simple,
weather-beaten villages where you wouldn't have thought it possible that
anyone could live. Discover sheltered, charming fishing villages under the
Midnight Sun in the summer, and the spectacular night skies with dancing
veils of Northern Lights in the winter. And in large towns like Bergen,
Trondheim and Tromsø, you will find art and culture, tourist attractions
and shopping to satisfy your every need.

Trondheim (
In Trondheim you can see:
- Nidaros Cathedral - see Social programme: Concert and reception
- The Archbishop's Palace - see Social programme: Concert and reception
- Stiftsgården - see Accompanying persons programme: Go for a stroll I
- The Tyholt Tower - see Accompanying persons programme: Sightseeing in
- The Wharves - The oldest of the wharves along the River Nidelva date back
to the 18th century, nevertheless they still give the impression of the
waterfront as it was long before then. On the seafront, towards the canal,
we find wharves that were built more recently, in the 19th and 20th

Lofoten (
Lofoten is the archipelago to the west in the ocean, north of the Artic
Circle, at the 67th and 68th degree parallels. Lofoten stretches like a
wall of moutains to the southwest in the sea. Between the mainland and the
"Lofoten Wall" lies Vestfjord. Lofoten consists of mountains and peaks,
wide open ocean, sheltered inlets, stretches of seashore and large virgin
areas. The principal islands are Austvågøy, Gimsøy, Vestvågøy, Flakstadøy,
Moskenesøy, Værøy and Røst. The total land area amounts to 1,227
About 24,500 people live there. The road distance is almost 170 km from
Fiskebø near Vesterålen in the north to Å in the south, where the E10 ends.
From Lofotodden, at the south end of Moskenesøy Island, the air distance is
more than 60 km to Skomvær, the southernmost point in Lofoten.

T1. Large Power and Industrial Drives by H. Raphael, W. Leonhard, P.
Lataire, A. Børnes, K. Ryen and T. Chr. Stensholt.

EPE offers the EPE'97 conference participants a package including:
- the technical visit to the Statoil Kollsnes gas terminal plant at the
outmost western island of Norway on 6 September 1997;
- transportation by bus along the Bergen archipelago to Kollsnes from
Bergen City Center or Airport and back to the costal express M/S Polarlys
(departure on 6 September at 22.30, arrival on 8 September at 06.00);
- tutorials at Kollsnes and on board of the Polarlys and technical visit of
the ship.

The Statoil gas terminal plant in Kollsnes processes the natural gas coming
through an undersea pipeline from the 472 m high off-shore Troll platform
(measured from the sea-bed) operating the centre of the world largest
offshore gas field.. The core of the plant are 5 gas compressors
individually driven by adjustable speed 41.2 MW synchronous motors.
Particularly interesting are the harmonics filers which are designed to
meet the specified harmonics
content. The filter design was a challenge due to the cable and overhead
line mixture in the power supply to the plant.
The gas transferred to Germany represents 400 TWh per year energy
equivalent, corresponding with a constant power of 45 GW.

T4. Adjustable speed a.c. motor drives, applications by P. Enjeti, F.
Blaabjerg and J. K. Pedersen.

Adjustable speed a.c. drives have become the preferred choice in many
industrial applications where controlled speed is required. At the
availability of fast solid state power semiconductor switches (IGBTs) has
resulted in voltage source, PWM controlled inverters becoming a standard
configuration in the power range to 500 kW. While high frequency PWM
control represents the most advanced drive concept, when inappropriately
applied, it also generates side effects, some of which have been recognized
only recently.
This course present a comprehensive coverage of application issues of PWM
inverter controlled a.c. motor drives which include: selection criteria for
energy savings, increased motor losses: damage to motor insulation due to
reflected voltages caused by long motor leads, acoustic noise problems and
solutions for sensor-reduction.
Following a description of the problems, several practical solutions are
also presented and nanlysed. Finally, line harmonic problems caused by the
input diode rectifier are also described and several low cost solutions
selected to meet IEEE 519-1992 are presented.
Basic content
Introduction to ASDs, application problems and energy savings;
Introduction of application problems to high dv/dt and long motor leads;
Filter configurations to minimize the motor winding stresses due to high dv/dt;
Application problems due to high dv/dt - continued;
Acoustic noise problems and their reduction;
Reduced sensing technique in ASD and their problems;
Power quality compliance of ASD equipment.

The audience
PWM inverter/motor manufacturers, system designers as well as adjustable
speed drive application engineers and users will find this course
informative and beneficial.

Matlab/Simulink, various industrial application examples in the fields of
power electronics and mechatronics are described. The first example is a
step up-down converter. The mechatronics applications are: simulation of a
pseudo-linear system (friction and stiction), frequency-voltage control of
an induction motor, vector control of an induction motor, wrist stiffening
of a bilateral Master-Slave force reflecting servomanipulator, control of
articulated boom of JET (Joint European Torus) and finally, active control
of an electromagnetic suspension system. For each application example, the
teaching includes a theoretical part (modeling, control design) followed by
the validation on a PC. As a conclusion, general design methodologies are
outlined and advantages and drawbacks of Matlab/Simulink are summarised.

T11. Understanding and complying with CISPR and IEC 1000 Standards on EMC
by A. Zuccato, L. Rossetto.

Since January 1996, electrical and electronic equipment sold in the
European market must bear the CE mark which attests compliance to EMC
standards, which take into account both radiated and conducted noises in a
very wide frequency range (up to 1 GHz) and require several emission and
immunity tests (including electrostatic discharge, fast transients, surge
voltages etc.).
The first part of the tutorial reviews the standards regarding
low-frequency emission and immunity to line disturbances, and in particular
IEC 1000-3-2 which limits the low-frequency harmonic distortion (from 50 to
2000 Hz) of equipment with rated current less than 16 A per phase. Common
problems and misunderstandings in applying the norms are addressed and
operational experience is reported for various families of industrial and
domestic loads. Then, basic passive and active power factor correction
techniques are illustrated and compared.
The second part of the tutorial reviews CISPR and IEC standards regarding
conducted and radiated noise emission and immunity. Typical problems
arising from their application are discussed from a practical point of view
and mitigation guidelines are given.
Lastly, the design of a power factor corrector circuit complying with all
the above standards is illustrated.

Integration of power components, state of the art and trends, by André A.
Jaecklin, ABB, K. Rischmüller, SGS-Thomson Microelectronics and Leo
Lorenz, Siemens

Part 1 by A. Jaecklin
The field of high power applications has recently experienced a strong push
from advances in device development. On one hand, Insulated Gate Bipolar
Transistors (IGBT) in the form of hybrid modules are continuously
increasing their limits in current („ 1500 A) and voltage (up to 4500 V).
In the highly demanding market of traction applications, reliability has
become on of the crucial issues, however. On the other hand, based on the
classical Gate-Turn-Off thyristor (GTO), a new element has been conceived,
called the Integrated Gate Commutated Switch (IGCT). This device implies a
rigourously reduced leakage inductance combined with a gate drive unit
implemented into the structure. Applying a hard gate drive (hard driven
GTO) opens the way to high voltages (> 10 kV) by means of multiple series
connection as well as to reduced losses due to snubberless operation.
Essentially, these two approaches are complementary.

Part 2 by K. Rischmüller
This part was not available by the time of printing

Part 3 by L. Lorenz
Power semiconductor components, including their further development as
monolithic power ICs, and hybrid system integration are the driving forces
behind advances in power electronics systems, particularly with regard to
energy savings, improved control response, noise redustion, size and weight
reduction and cost minimization. The first attempt at hybrid integration
was the implementation of IPM's, ASIPM's and PIM's. The PIMs and ASIPMs
currently known consists of a package containing all the power switches
including brake chopper with drive/protection circuitry. However, today's
IPMs, ASIPMs have several advantages concerning interface, cost and system
requirements. As a result of all these disadvantages, these solutions have
no future and will be superseded by system integration in the medium term.
This paper highlights the new approaches to system integration based on
chip level.

are the main advantages and disadvantages of each components, what could be
the optimal application field?


Animator: Dr. Richard Duke, University of Canterbury, New Zealand
The occasion of EPE brings the rare opportunity for international
comparisons of power electronics educational systems. Each country of
group of closely associated countries has developped its own unique
educational system and power electronics education has developed and
flourished in different ways to meet varying needs. What position does
(should) power electronics hold in the undergraduate (graduate) programme?
Should power electronics be a required course for all EE's, for all EE's
specialising in power or is an elective arrangement more appropriate?
There is a commonly held perception that power electronics education is
often inadequate, especially with respect to practical experience in
instructional laboratories. Should lectures and laboratories be an
integrated package or are separate laboratory courses more appropriate?
Are the traditional electrical machnies courses still appropriate or should
there be more effort to integrate power electronics into such courses?
To initiate discussion of these question, and others, some brief results
from international survey of power electronics education in Australasian
and North American Universities will be presented.

Post Conference Technical Trips

1. Visit at Hydroelectric power stations

In the river Nidelva, which runs through the city of Trondheim, the energy
company Trondheim Energiverk (TEV) operate seven of its hydroelectric power
stations. A technical tour to two of these stations will be arranged.
Although the river is regulated for hydroelectric power production it is
considered as one of Norway's best fishing sites of Salmon with a record of
catch-up of up to 1 ton per km/year along the stretch where fishing is
Nedre Leirfoss is a power station which was put into operation in 1910. The
installed capacity is 12 MW and the average production is 67 GWh/year.
TEV has a small museum at Nedre Leirfossen which shows the evolution of the
technology at their power stations from 1910 until today. The Brattsberg
power station is a typical example of the new generation Norwegian power
stations and was put in operation in 1977. It is located inside the
mountain and water is led through tunnels (not pipe-lines) to the turbines.
The installed capacity is 120 MW and the average production is 600
The participants will be picked up by bus in the centre of Trondheim at
10.00 on Thursday 11 Sept. A light lunch will be provided at Brattsberg
Power station. After the visit, at 13.00, the participants will be
transported directly to Trondheim Airport, Værnes, by bus.

Fee for the tour: 100 NOK

2. Visiting Siemens A/S, Trondheim,

Siemens A/S is a worldwide company with sites in 181 countries. Siemens A/S
was established in Trondheim since 1908. For the time being Siemens has
2750 employees in Norway and 830 out of these are in Trondheim. Siemens A/S
in Trondheim has two factories. One produces electric heaters and the
other produces middle voltage equipment, motor control cubicles and power
electronic circuits.
Siemens A/S power electronics department is in Trondheim. This department
is a competence centre for power electronics in Siemens A/S. The Power
Electronics department is specialised in UPS, rectifiers for aluminium
industry and converters for railway power supply.
On this visit to Siemens A/S here in Trondheim you will get the opportunity
to get a presentation of Siemens A/S in Trondheim especially the Power
Electronics Department and to visit the factory. After lunch there will be
a guided tour to Stavne converter station which as 2 MVA, 16 2/3 Hz
converter for railway power supply. Siemens A/S was the contractor to this
converter station.
The bus will collect you at Trondheim centre at 09:00 and return at 14:00
to Trondheim Airport, Værnes.

Fee for the tour: 100 NOK
3. Train trip to Adtranz near Oslo

Adtranz is organizing transportation from Trondheim to Oslo by train. We
start in Trondheim about 8.00 in the morning, then we will pass the
mountain plateaus and see the glaciers in full daylight. There will be a
draw, one of our guests will be invited to stay in the locomotive from
Oppdal to Dombås. This is over the largest mountain plateau, where also the
speed is fastest.
We will present our locomotives in the train as we go along with emphasis
on the EL 18 locomotive of our train. Of couse we will tell a lot about the
tilting trains. We just got one order of16 (!) trains to the Norwegians
State Railways of one Billion NOK. In Norway straight rails are rare, 80%
of the distance is a curve. So tilting trains is the only way to increase
the speed. There is not enough trafic to allow for new railways.
We will serve coffee and later on lunch in the train.
The first EL 18 locomotive was delivered from the Strømmen factory of
Adtranz Norway in the Summer of 1996. It is the first of a series of 22
locomotives, all will be made before 1998. Both passengers and goods will
be pulled by these new locomotives, and a lot of more than 30 years old
locomotives will be replaced. EL 18 is a Norwegian modified version of the
Loc 2000 family. The specifications of the Norwegian State Railways are
among the strictest in the world due to rough weather, temperature
extreemes and blowing snow particles. In addition there are problems with
condensation in the long tunnels.
The locomotive is made with welded steel and some copper to avoid rust. The
cabin for the engineer is made with a low weight glasfibre sandwich design.
The boggies are radial controlled and follow the rails with low friction,
better utilization of the traction power and less wear of the wheels and
the rails than the older locomotives. Robust induction motors controlled by
GTO voltage source inverters are Adtranz standard technology.
Also the rectifier converters are like this, providing four quadrant
sinusoidal 16 2/3 Hz input current. The maximum power at the wheels is 5.88
MW and the maximum speed is 200 km/hour.
The train will stop close to the Strømmen factory just outside Oslo, at
about 14:40. There we will invite you to a special press conference where
we will disclose a new train! Our international EPE '97 guests will improve
the atmosphere of the presentation, so we will both benefit from this.
