noted that the static calculation assumes that load is spread equally

3 BASELINE OPTION 3.1 Station Planning and Operations
This is the previously proposed scheme (phases 1-3) with the new
Bressenden Place ticket hall and staff accommodation at basement level
below the south end of Bressenden Place and the properties on the north
west corner of Bressenden Place and Victoria Street (120-124). There
are three stairway connections to street level; one with compact
escalators. There is space for plant rooms and a ticket office at
basement level.
A bank of three escalators runs from the ticket hall down to a concourse
above the Victoria Line platform level. From the concourse, access to
the north end of the Victoria Line platforms is by stairs. Access to the
District & Circle Line platforms is via a ramped passageway to the
existing interchange concourse.
A mobility impaired person (MIP) lift runs from street level to the unpaid
side of the ticket hall. A separate lift on the paid side connects the ticket
hall with passageways above the platforms. A further lift runs between
this passageway and the Victoria Line platforms.
A new bank of three escalators links the south ticket hall to an extension
of the existing interchange concourse. MIP access is provided from
street level down to the existing south ticket hall, and from the ticket hall
level down to the interchange concourse. New sets of stairs and MIP lift
provide access to the westbound D&C platform. A MIP lift is also
provided to the eastbound D&C platform. A slightly improved link is
provided between the south ticket hall and the Network Rail station by
widening the existing western stairs.
The scheme has the following shortcomings:
Additional demand is directed to the existing interchange concourse
resulting in an average level of service E – F with 2016 (+35%)
demand over the 3 hour peak period, which is unlikely to be
acceptable to HMRI.
It does not provide the LFEPA requirements for a lift or stairs to
access the Victoria line platform direct from street level.
MIP step free access from the Mainline Station to the Victoria
Platforms is at street level via the north ticket hall only.
The proposed stair extension to Victoria mainline station does not
address the main capacity problem ie the Kent stairs
No suitable site has been identified for a new station operations room
(SOR) including dedicated access to street level.
The new escalator construction from the south ticket hall takes
existing accommodation although no additional space is allocated
elsewhere.
The proposed northern platform access would appear to clash with
the piles indicated on the existing Elliot House construction drawings.
It is therefore not clear whether the scheme can be constructed
without acquiring this building
Whilst the increased capacity provided will reduce the probability of
congestion arising on the Victoria Line platform. It will be insufficient
to eliminate entirely the need for pro-active station management in
the event of delays arising on the Victoria Line train service,

unexpected surges of traffic from the main line station, or the lack of
available escalators due to defect or maintenance.
As the proposed south ticket hall to Victoria line platform route via the
interchange concourse is longer than the existing direct route KEY PASSENGER FLOWS
(especially for passengers wishing to access the train at the southern
end), the effective utilisation of this new route will rely heavily on
station management
3.2 Passenger Flows
3.2.1 Southern Ticket Hall
All four schemes propose an additional set of escalators down from south
ticket hall diverting a proportion of Victoria Line boarders away from the
existing set of escalators and relieving congestion at the southern end of
the platforms. However, the existing escalators provide a much more
direct route to the platforms (shorter journey times). It would, therefore,
be necessary to implement operational measures to successfully divide
the entry flow between the two routes.
The Baseline scheme proposes four escalators in the up direction, and
two going down. Four out escalators is two more than required in terms
of demand, with two escalators down being one less than required. The
total provision of six escalators is adequate providing the current rule for
more total escalator numbers up can be relaxed.
3.2.2 District & Circle to Victoria Interchange
A key element of station infrastructure is the interchange concourse that
currently links the Victoria Line to the D&C Line. The Baseline scheme
links in to this concourse, whilst allowing the entry flow from the Victoria
Line Ticket Hall to distribute more evenly along the Victoria Line
platforms. The additional flow through the interchange concourse would
create very high congestion levels, to operate at a Level of Service (LOS)
C with the additional demand through this space requiring an area of
2 2
267m when the current area available is 116m .
The flow from south ticket hall street to Victoria Line platforms using this
new route will also impact upon the escalators leading down to the
platforms. Whilst the required two escalators up are satisfied by the
proposed design, this increase in passengers going down requires a
further two escalators, which exceeds the one escalator proposed.
The Baseline scheme replaces the existing link between D&C WB and
the interchange concourse, which results in longer journey times for this
route.

4 MODIFIED BASELINE OPTION
4.1 Station Planning and Operations
This option retains many of the features of the baseline scheme but
seeks to address the short comings identified. The baseline scheme has
been modified to improve or rationalise passenger flow and MIP access.
The following is proposed:
Increase space adjacent to the interchange concourse.
In accordance with the latest station planning standards and
guideline requirements provision of an inclined lift in place of one of
the new escalators from the south ticket hall towards the Victoria line
platforms. Whilst this should be acceptable, however, having only 2
new escalators will provide no margin for escalators out of service.
The use of MIP facilities is expected to be high at Victoria where
many passengers are encumbered with luggage. The use of this
inclined lift needs further evaluation in terms of capacity, frequency
and waiting arrangements compared to the alternative of the
conventional MIP lift.
Provision of 2 No NED escalators at the north end of the Victoria line
platforms (rather than stairs).
Provision of a travelator to the south eastern paid area link. It is
envisaged that this will be travelators operating in the peak direction
with an adjacent passageway.
Enlarges the existing South ticket hall box to provide space for a new
Station Operations Room (SOR). The practicability of using the
available space will require further detailed consideration.
Create one way system for flows between the D&C lines and the
interchange concourse
Provide MIP access to the Victoria Line via the interchange
concourse.
Provision of 2 MIP lifts from the main line station to the Victoria Line
ticket hall, thereby remedying a previous deficiency.
Provision of a separate widened area between the galleries adjacent
to the existing interchange concourse giving improved space for
decision making at the route junction and keeping the passenger
route from the south to the north gallery clear of the crowded
interchange concourse.
This scheme still does not provide a firemen’s lift or stairs for the
LFEPA to access the Victoria Line platforms direct from street level.

consequently rises to 298m in order to maintain LOS C.
KEY PASSENGER FLOWS
Similarly to the Baseline scheme, the flow down from the interchange
concourse to platforms requires two escalators, but only one is proposed.
The total up and down requirement with +35% is four, but it is only
possible to retain the existing three.
4.2.3 Northern Ticket Hall
The Modified Baseline scheme replaces the stairs to the north ticket hall
at the northern end of the platforms, with two escalators, which are able
to accommodate demand.
The provision of three escalators in the north ticket hall is sufficient.

5 MINIMISED PROPERTY ACQUISITION OPTION 5.1 Station Planning and Operations
This proposal includes the modifications to the baseline scheme and the
following:
Construct LFEPA lift/stair outside the boundary of Elliot House to
access the Victoria Line platforms direct from street level.
Provide 2 No compact escalators/stairs at the north end of the
Victoria line platforms (rather than stairs). These take passengers
to a below platform level to avoid Elliot House piled foundations
(assumed).
New cut and cover box under Bressenden Place highway with no
additional requirement to acquire 120-124 Victoria Street. NB This
concept requires further detailed space proofing to ensure all
station accommodation can be provided .
A MIP lift from the North ticket hall to the Victoria Line platform,
however, this is separated from the normal passenger routes and
may pose a security hazard.
5.2 Passenger Flows
The three down escalator requirement for Victoria Ticket Hall is again not
satisfied in the Minimised Property Acquisition scheme, but as previously
noted; modifying escalator orientation would overcome this issue.
This option has the travelator along the new route from the south ticket
hall to Victoria Line platforms, improving the journey time and therefore
the attractiveness and proportion of people using it. This high flow
feeding into the interchange concourse is added to by a new link to the
north ticket hall for an assumed proportion of people going to and from
the Victoria Line platforms. This scheme, therefore, receives the highest
passenger volumes within the interchange concourse, resulting in a
required area of 345m2 for LOS C.
As expected, this increased flow from the concourse down to platforms
puts even more pressure on the escalators, which are now considerably
under capacity with five required to satisfy the flow.
At the northern end of the Victoria Line platforms, two escalators linking
to north ticket hall are sufficient, and as is the case with all four schemes,
there are no issues regarding provision of escalators in the north ticket
hall. However, the design of the north ticket hall in this scheme generates
the longest journey times, since the route to the northern end of the
Victoria Line platforms goes down beneath them, thereby covering more
vertical overall distance.

6 ELLIOT HOUSE TICKET HALL OPTION 6.1 Station Planning and Operations
This proposal accepts that the construction of escalators at the north end
of the Victoria line may require the acquisition of Elliot House. This site
could then be developed as a ground level station entrance with a
development over. The scheme, which also addresses the issue of the
overloaded interchange concourse, includes the following:
A ground level ticket hall on the site of both the high rise and lower
section of Elliot House.
MIP lift to be provided in a single shaft to Victoria line platform level.
Ground level access for the LFEPA is also possible with stair and
lift to the platform.
New road crossing or utilisation of the existing subway under
Bressenden Place to allow safe access from east side.
The escalator route from concourse to interchange level is in a 180
degree turn configuration via a landing under Allington Street at +
99m.
The addition of 2/3 No compact or 2 NED escalators at the north
end of the Victoria line platforms (rather than stairs) linking to the
new Ticket Hall box.
The nodal point at the base of the D & C interchange stairs
(eastbound) is to be designed to allow a future escalator connection
to a remodelled District and Circle line concourse.
The existing interchange concourse is enlarged as far as possible
to the east to provide improved space for decision making at the
junction of route to both ticket halls.
Add new paid area link to west of station to take interchange flows
from Vic to eastbound D & C. This does not connect to the
interchange concourse during peak times. This connection
amends/extends the existing stairs to the D & C and removes one
of the adits off the interchange concourse.
Add travelators to the 2 long paid area links. It is envisaged that
these will be one-way travelators operating in the peak direction
with adjacent passageway.
Enlarge the south Ticket Hall to the west and east to provide space
for displaced station accommodation and compliant station
facilities.
Creates one way system for interchange flows with the D & C
MIP access to the Victoria Line is via the interchange concourse.
Widening of the existing concourse stairs to the mainline station is
proposed. The intention is to examine the widening of the Kent
stairs which are currently the more congested. MIP lifts are also
proposed at the” threshold” of the station.
New stairs replacing the existing Wilton Street stairs are proposed.
The detail of these will need to be integrated with future street
crossing locations. Indeed passive provision for a further stair
entrance on the proposed public square outside the station also
needs to be considered.

Stage B+ Option Review
6.2 Passenger Flows
All schemes provide a sufficient number of up escalators to south ticket
hall but only the Elliot House option satisfies the required number of
down escalators. This is because the flow going from street entry to D&C
EB is removed from the new infrastructure in this scheme via the
Interchange Concourse. However, as noted, orientation of escalators
would resolve this capacity constraint in other options.
The street entry to D & C EB removal along the new route from Victoria
Ticket Hall, also reduces the flow of passengers being routed through the
interchange concourse. Relieving congestion in this concourse is
absolutely necessary since it is of limited size and receives a significant
volume of passengers. Its 116m2 area cannot be increased due to
structural limitations and consequently the only way to address the
problem is to redirect some passengers via alternative routes. The Elliot
House Ticket Hall scheme aims to do this by removing D&C passengers
from the concourse. In order to achieve LOS C pedestrian density in the
interchange concourse, all four schemes fail to provide sufficient space.
However, this scheme requires the least space at 197m2, resulting in the
lowest congestion given a fixed area of 116m2 in all four schemes.
A reduced level of congestion in the interchange concourse would create
generalised journey time savings when calculated with congestion taken
into account.
By directing D&C interchangers and D&C TH entry/exit flows through the
Bressenden (north) end of Victoria Line platforms (proposed western
travelator link), the Elliot House scheme relieves the load on the
escalators between the interchange concourse and the middle of the
Victoria Line platforms. With +35% demand, the three other schemes
require four or five escalators whereas this scheme copes with the
existing three.
Journey times for D&C to Victoria interchanging passengers diverted
away from the Interchange Concourse would increase. However, overall
generalised journey times through the concourse improve and thus
provide a contribution to the business case.
Generalised journey times for those passengers using Elliot ticket hall are
up to 100 seconds longer, compared to other north ticket hall options
based on common entry on the corner of Bressenden Place and Victoria
Street.

Stage 1 – Victoria Line Platforms
Additional Running Tunnel
This generic option includes an additional running tunnel and
platform, as previously proposed in option 4K (10). This could be
designed as a 2 or 3 platform face variant.
The advantage of this approach is to create more passenger
space at platform level with a greater provision of vertical
circulation.
Reasons for Rejection:
Though not unprecedented within LUL it cannot be achieved
without massive disruption. This scheme was primarily rejected
due to the need for a partial line closure and excessive cost. No
further study proposed.

Low Level Exit Gallery
This option provides additional platform capacity by the
construction of a new exit only gallery parallel with the northbound
Victoria line platform. New audits would need to be constructed
from the gallery to train door locations implying the use of screen
doors and train stopping technology to suit. An alternative would
be to enlarge the northbound platform tunnel to give two platform
faces (boarding and alighting) within the same tunnel.
Reason for Rejection:
This approach separating borders and alighters would assist
smoother passenger movement and possibly reduce dwell time.
This scheme was primarily rejected because it is not possible to
construct the work without line closures. No further study proposed

This proposal provides new passenger links from the Southern

Reasons for Rejection:
This arrangement would require the wholesale and reconstruction

An option was examined to use the 3 existing Victoria line
escalators as out only in the am peak period. New escalators
linking with the interchange escalators would be used for boarding
passengers. Passengers wanting to wait for trains at the extreme
south end of the northbound platform would flow along the
platform in the same direction as the exiting passengers.
Additional D and C interchange arrangements would be needed at
the north end of the station.
Reasons for Rejection:
The platform is too narrow to encourage flows along its length.
The system provided is inflexible and restricts opportunities for
passengers to exit the platform. The large flows entering the
Victoria line are disadvantaged as are all D and C interchange
passengers.

Stage 2 – Platforms Retained
Platform(s) Extended to South
This approach accepts the location of the existing bank of
escalators from the Victoria Line concourse to the platform and
extends the platform tunnels southward to form a new train
stopping position. In this way the extreme end loading is avoided
and a greater proportion of the platform is utilised effectively.
This principle of extension could apply to both or the northbound
platforms only.
Construction Methodology:
Two options exist:
Line closure
Live encirclement of the running tunnel to create a tunnel of
sufficient diameter for the extended platform in Engineering Hours
A live encirclement was not considered to be a viable option, given
the concerns regarding impact on the safe operation of the
existing service and the prolonged duration of construction (likely
to be in excess of one year).
Secondary considerations relate to the use of hand mining
techniques, which would be an inevitable consequence of this
option. Current legislation would limit hand-tool trigger time to
approximately 10 minutes per man per shift resulting in excessive
construction durations and/or unrealistic gang sizes. Coupled with
only 2 hours per day of realistic working time within engineering
hours, live encirclement is not viable.
The following technical assessment is therefore based upon the
assumption of Line Closure.
Reasons for Rejection:
Line Closure will result in severe operational disruption to the
existing Victoria Line Service, which are unacceptable to LUL
Potential clash with existing Victoria Line Ticket Hall escalator
Extensive ground treatment required, which would result in high
cost and excessive construction duration. No further study

Stacked Interchange Concourse Escalator
Brief Description:
New tunnel (driven under Victoria Platform Tunnels ~78m) from (a
low level concourse) in the Northern Ticket Hall Box to ~78m
leading to an additional southern escalator access point nested
beneath the Interchange Concourse escalators.
Construction Methodology:
Prior to start of tunnelling all cross passages and “service” rooms
which are to be abandoned are to be filled with foam concrete (or
similar). London Clay interface expected to be at approximately
+93m tunnel datum. Tunnels driven above the London Clay will
require ground stabilisation techniques (probably from the tunnel
face). The majority of the tunnels on this option are however to be
driven at a low level and therefore in the London Clay (exception is
the MIP lift tunnel). Tunnels to be constructed using permanent
sprayed concrete lining techniques (incorporating a waterproof
membrane).
Box structures constructed using either diaphragm-wall or secant
piles.
Reasons for Rejection
Stacking of escalators is not feasible without significant disruption
to the operation of the station for a period in excess of 18 months
Relocation of services is considered to be problematic. Additional
space to accommodate these services could possibly be provided
in a purpose built shaft or tunnel below the existing rooms 5/382
and 5/383 (or Bressenden Box). No further study proposed.

POLICY STRA 17: NOISE
It is the City Council’s aim:
To reduce noise levels in Westminster below maximum noise levels set out in the World Health Organisation
‘Guidelines for Community Noise’.
Noise is an aspect of amenity that affects everyone. much of the high level of noise in Westminster is
generated by transport, including road and rail traffic, aircraft and water transport. Policies ENV 6 and ENV 7
in Chapter 9: Environment, in Part 2 of the Plan, set out how we will seek to reduce noise levels below specific
maximum noise levels set out in the World Health Organisation (WHO) ‘Guidelines for Community Noise’

POLICY STRA 18: CRIME AND SECURITY
It is the City Council’s aim:
To reduce the fear of crime, actual crime and nuisance for residents, businesses and visitors.
Crime and the fear of crime are important and increasing concerns of residents, business and visitors. They
have a very great effect on people’s perception of places. Section 17 of the Crime and Disorder Act 1998
requires community safety to be considered in all decisions made by local authorities including those on
planning applications. Developments should be safe and secure through informed design.
POLICY STRA 20: INTEGRATING LAND USE AND TRANSPORT
It is the City Council’s aim:
To reduce the need to travel, whilst improving access to facilities and services, by integrating land use and
transport policies in cooperation with other bodies across London.
