3.2.3       Main Cable Entrance

One or two 5 inch wide cable “slots” must be provided for main cable chutes.

Housings require the following chute sizes:

            •   6 x 8 housing : 5” x 24” x 24”;

the chute(s) is to be 24 inches.

3.2.5       Cable Entrance/Surge Panel

Current Railway practice indicates that the use of a housing surge protection technique
referred to as “Faraday Cage or Dirty Wire Enclosure” is recommended for all cables
and wires entering the housing.

The principle is that an electrical energy applied to an enclosed conductive enclosure will
be forced to the outside of the enclosure by the repulsion force of electrical charges. To
make this effective, any conductor that penetrates the conductive enclosure must be
surge limited and referenced to the enclosure i.e. have an arrestor or protector. This
includes all trackside conductors including spare wires, power conductors and antenna
coax cables.

This design uses the welded aluminium skin of the bungalow as the conductive surface
and builds an internal “closet” that is a continuous conductive surface with the outer skin.
For maximum surge protection, the arrestors and protectors must be connected to the
outside conductive surface by a connection that is as short and conductive as possible.

“Dirty” Field wiring (pre-surge arrestor wiring) is terminated in the closet as indicated on
the circuit plans which accompany the specification. This wiring and the surge energy
that can radiate from it is shielded from the active equipment (that is inside the main
bungalow‘s “clean” area) by the metal barrier formed by “Arrestor” panels.

Technical specifications                                                                9

All major suppliers of signal housings have developed a method of providing this type of
protective enclosure and will be acceptable for use providing the wiring conforms to the
circuit plans noted above.

3.2.6       Ventilation and Heating

As illustrated on the circuit plans, proper ventilation and heating equipment that will
maintain the internal environment within the normal operating temperature for the
electronic equipment proposed is required.

approved, thermostatically controlled, 120 VAC as indicated on the circuit plans. The fan
is to be serviced from a separate circuit breaker within the main power distribution panel.

A 1500 watt forced air heater must be provided. The heater is to be controlled from a
separate thermostat and breaker from the main power distribution panel.

3.2.7       Electrical Requirements

The housings must be wired in accordance with applicable provincial and local power
codes. A main power distribution panel of the Square D QO-11600GC or equivalent,
circuit breaker type is required. Standard 100 amperes service entrance mast must be

3.8.1        Telecommunications installations

a)           Description of the installations

The telecommunications installations covered by this request for proposals comprise two
aspects :

•       Voice transmission ;

•       Data transmission.

The voice aspect covers the ground-train VHF radio communications between the
dispatcher and the train operators. The data aspect is primarily the commands and
controls made by the signaling equipment.

CPR’s overall needs, in terms of telecommunications, are served by a main fibre optic
line using digital transmission technology that runs from Vancouver to Montreal, and
then to United States. The Montréal/Saint-Jérôme branch line is not covered by this line.

On this branch line, CPR uses dedicated, specially prepared telephone pairs, leased
from Bell Canada, to ensure voice transmission between the radio bases and the
dispatcher. For data transmission, i.e. remote control of the signaling equipment by the
dispatcher and control of the data from the signaling equipment to the dispatcher, CPR
uses the digital radio system provided by SAFETRAN.

To extend the Montréal/Blainville commuter train line as far as Saint-Jérôme, it is
necessary to ensure that the CPR dispatcher is permanently in contact with the train
operators, whether they are in the driver’s cab, on the move inside or outside the train,
or along the track, for any reason whatsoever.

According to the results of a propagation study conducted several years ago by the CPR
telecommunications department, the VHF radio communications between the dispatcher
and the train operators (in the driver’s cab) is to be provided by the base located in

For the other cases, an additional radio base at the Saint-Antoine garage is to be
provided. Accordingly, a button must be added to the CPR dispatcher’s exiting control
panel. Also, the base is to be connected to this control panel using dedicated telephone
pairs leased from the Bell Canada.

The radio base in the Saint-Antoine garage must include :

Technical specifications                                                             14

     •   a 30-W Kenwood TKR 750 emitter-receiver ;

     •   a duplexer ;

     •   an interface between emitter-receiver and the telephone pairs ;

     •   a Yagi antenna, installed on a 21-m treated pole and connected to the base by a
         coaxial cable ;

     •   a charger and a set of batteries ;

     •   a standard 19-inch cabinet for mounting the equipment ;

     •   connecting cables, connectors, cable shelves and conduits.

b)          Equipment to be provided

The Contractor must provide all of the equipment listed in the price schedule. As
indicated above, this list is not exhaustive. The Contractor must complete it with anything
necessary to ensure the installation is in perfect working order.

The equipment specified is identical to that currently used by CPR.

The batteries must be maintenance-free, odourless, nickel cadmium. Their capacity is to
adequate to ensure operation of the installation for a minimum period of eight hours, in
the event of an extended outage on the 110-volt line.

For the signaling aspect, the Contractor must provide and install radio equipment from
SAFETRAN as shown on the installation diagrams of appendix B.

c)          Equipment installation

The Contractor must install the equipment while respecting industry standards, in
addition to respecting current practices used in railway industry.

The treated wooden pole must be installed at an appropriate location in agreement with
the AMT project manager. The other equipment must be installed in a room to be
designated by AMT, inside the Saint-Antoine garage. The radio equipment requires a
room 10 ft. by 8 ft. The Contractor must specify the exact dimensions required, if smaller
than anticipated. It must also ensure that its cable entry into the building is perfectly
watertight and respects the building’s esthetics.

The installation diagram, provided in appendix B, is only a guide to the Contractor in
presenting its own detailed diagram for approval by AMT.

Technical specifications                                                               15

Regarding the dispatcher, a new button is to be added to its control panel for the new
bas at Saint-Antoine. This portion of the work will be done by CPR, but the Contractor is
required to coordinate its work with the latter.

d)          Commissioning of the installations

The Contractor must perform all of the tests to ensure the proper operation of the
equipment installed, in the presence of the Client’s representatives. Once validated, the
installations must be commissioned by the Contractor, in the presence of AMT (the
Client) and CPR (the Operator) representatives.

When commissioning the radio base at Saint-Antoine (the CPR dispatcher controls and
operates this base), the emitter power will be adjusted experimentally to a level that
creates the least possible interference with the Sainte-Rose base, while ensuring
reliable, good-quality communications.

As CPR does not have additional frequency available, it is necessary and mandatory to
use the same frequency as that of the Sainte-Rose base. This would have the effect of
creating beats in the midway area between the two bases, if the two bases were
operated simultaneously. Accordingly, it is necessary to ensure that the two bases are
never on air at the same time, which is also a CPR operating rule. However, for
communications from the train to the dispatcher, the latter will select the base that
receives the best signal.


The approach taken to the provision of grounding appropriate to the equipment used
within this signal project is to provide a central exothermically connected chemical
ground rod at each housing. The central rod must be interconnected to the main copper
ground buss within the housing.

The chemical ground rod required for this project is specified as a kit available from
Erico under number ECRH101T4U, 10’ horizontal with #2 solid (4’Length in up
orientation with backfill and well).

All exterior signal cables and wiring must enter the housings through a “Faraday
Cage/Dirty Wire Enclosure” type of entrance panel with the appropriate lightning and
surge protection provided within that entrance panel and as shown on the circuit plans.

The exception here is that the AC power cable/wires will enter through the usual service
entrance pipe and have its own surge protection.

Technical specifications                                                             16


3.10.1      General Practices

The following are some of the general practices that apply when wiring vital S&C
•   Wiring between equipment located on different bungalow walls are to be run either in
    overhead cable trays, where provided, or in surface wire way. Surface wire way is
    defined in section
•   Special precautions must be taken to ensure that the surface wire way is arranged at
    wall corners so as to provide mechanical protection to the wiring. All corners are to
    be checked for sharp edges or metal burrs which could damage the wire insulation.

•   All conductors within surface wire way or cable trays are to be run straight and
    parallel unless otherwise specified as twisted wires on the approved circuit plans.

•   Wire must be laid in surface wire way or cable trays loosely without stretching or
    crowding and must not be doubled back. Splices or any type of repair to wires are
    not permitted.
•   Wires must be visually inspected as they are being pulled from spool to assure there
    are no splices or defects present. Spool length markings that reveal more than 1
    length could indicate that splices are present in the coil.

•   Wire leaving surface wire ways or cable trays must be harnessed together and tied
    using tie wraps or other approved material. The length of ”exposed” vital circuit wiring
    must be kept as short as practicable.

•   Wire routing is to be accomplished in a manner to present a neat and orderly
    appearance, and to ensure that wires are protected from chafing, damage from
    moving or heat dissipating parts, interference with other assemblies or elements, and
    damage from vibration.

•   Surface wire way and cable trays may contain any number of conductors. The
    Contractor must ensure that the aggregate cross-sectional area of the conductors
    and their insulation do not exceed 70 % of the interior cross-sectional area of the
    surface wire way or cable tray, after allowing for future expansion.

•   No more than two (2) wires may be connected to a single AAR terminal.

3.10.2      Wire Specifications

All case wire types approved for use on new S&C equipment housing and signal
apparatus must be EPR type insulation with PVC jacket. Wires must be constructed of
19 strands ASTM B-8 Class C tinned copper with ethylene propylene rubber insulation

Technical specifications                                                                17

(EPR), colour black, with polyvinyl chloride jacket, colour blue, in accordance with
AREMA Signal Manual Part 10.3.15.

The 3 standard wire types, known as A, B, and C, which refer to the 3 recommended
gauge sizes, are used in the typical applications as shown in the following tables. Wire
sizes shown in these tables are the minimum sizes allowed.

3.10.3         Equipment Identification and Tagging

In order to facilitate the proper identification and wiring of the equipment (devices) used
in a signal bungalow or housing, each device must be tagged in accordance with the
nomenclature identified on the Signal Design drawings.

The design and mounting criteria for internal equipment tags is as follows:

•     Some equipment tags will vary depending on the type of equipment and
      manufacturer. Where provided, the Manufacturer’s equipment identification method
      and tagging system must be used. For example, use Wago Terminal Tags on Wago
      Terminal Blocks;
•     Surface mount equipment tags must be white or light grey, high humidity/heat and
      fade resistant, non-metallic material (plastic) with self adhesive backing to permit
      applying to wood, Bakelite, plastic and/or metal surfaces (painted and non-painted);
•     Equipment tags designed for insertion into equipment;

Technical specifications                                                               18

            o   Specific tag receptacle must be white, high heat/humidity, fade resistant,
                non-metallic material (plastic);
            o   Equipment tags are to be located in a conspicuous location on the
                equipment itself;
            o   Equipment tags must be white, with black lettering;
•   Hand written tags/labels are acceptable on a temporary basis, so long as they are
    clearly legible;

•   The tag size, location and font size can vary depending on the application, with
    larger tags appropriate for racks and entrance boards. A simple font such as Arial,
    must be chosen, for easy readability.

3.10.4      Wire Identification and Tagging

There are two methods recommended in AREMA Signal Manual Part 16.1.1,
Recommended Circuit Nomenclature. These describe processes which require
individual wire tagging, the intent of which is to ensure correct component connectivity
and aid in the eventual wire tracing and trouble shooting of the installed signal system.
The two methods are:

The Termination Nomenclature Method - This method requires the “termination” point
to be marked on the tag on each end of the wire. This is the preferred method for use
for this project.

The Circuit Nomenclature Method - This method requires the “from and to” information
in addition to the wire nomenclature to be marked on a wire tag on each end of the wire.

Note: AREMA Part 16.1.1 states “Combinations of the two methods may be used”.    Internal Wire Tagging

Standard wire tagging must be based upon the Termination Nomenclature Method with
additional nomenclature that identifies the circuit.

Example: The main terminal Board 2TR (-) track feed direction Tag must read 2TN,
A37. The wire nomenclature on the circuit plan must read “2TN” and the termination
point as row A, terminal 37.    External Wire Tagging

External equipment/housing terminal and associated equipment junction box wiring are
to be tagged in accordance with the terminal board number and nomenclature as shown
on the circuit plans.

Technical specifications                                                              19

This includes colour-light signals, base of signal mast junction boxes, cantilever signal
junction boxes, gate mechanism signal junction boxes, light arm signal junction boxes,
switch machines, switch machine junction boxes, switch circuit controllers etc.

Example: Switch Machine terminals (normal position indication circuit) in the contactor
compartment. Tag must read 7ANWC, A6. The circuit plan shows the number “7A”
switch machine normal indication wire, terminating on row A, terminal 6 of the switch
machine.    Wire and Cable Entrance Panel

In housings using Faraday Cage/ Dirty Wiring type of entrance panel, both terminal and
row designation equipment identification tags must be provided on each side of the
entrance panel. A separate wire tag is required for each wire terminating on the internal
and external sides of the panel.    Tagging Specifications

Wire tags for internal equipment wiring and external apparatus wiring must be “Brady”
type, white, plastic, humidity and heat resistant, sleeve type wire tags, sized to permit (2)
rows of (12) characters of nomenclature. The type must be clearly legible.    AC Power Wiring

AC power equipment mounted directly to plywood walls, backboards, or equipment
racks must be wired with Type RW90 flexible wire in certified electrical metallic tubing
(EMT) or Armoured Cable type AC 90.

Recommended colour code for AC power circuit applications.

                 Voltage                               Recommended Colour
             AC Voltage 110v                      one black and one white conductor
           AC Voltage 230 volts                    one black and one red conductor

Recommended Cable and wire sizes/types for AC power applications.

     Branch Circuit Rating        Using Armoured Cable type AC90             Using EMT
            15 Amps                    AWG-14 type AC90 XLPE             AWG-14 Type RW90
            20 Amps                    AWG-12 type AC90 XLPE             AWG-12 Type RW90

All cables must meet or be approved equal with CSA or NEC specifications. Cable must
be cross-linked polyethylene insulated.

Technical specifications                                                                 20
(CONSTRUCTION CONTRACT)    Circuits in Excess of 32 Volts AC or DC

Terminals used in circuits operating at a nominal 32 volts or more must be protected by
the use of insulated nuts or insulated cap and shield assemblies.

Where practicable, such terminals are to be grouped together and away from lower
voltage terminals and equipment. These terminals must be clearly tagged with the
voltage level.

Equipment, such as fuses and lightning arresters, which operate in circuits of nominal 32
volts or more and which have exposed, live metal parts, must be equipped with
protective covers or shall be installed in protective enclosures.    Over Current Protection

Over current protection in the form of approved circuit breakers or fuses must be used in
all power circuits and busses operating at a nominal 32 volts or higher. The over current
values are to be determined by the weakest thermal link of the circuit. For example; a
#10 wire feeds a transformer rated at 15 amps, the #10 wire is rated for 30 amps and is
used to reduce the voltage drop. In this case the fuse or breaker must be rated for 15
amps. The ratings of the fuses and breakers must be governed by provincial and local
power codes.    Grounding and Bonding

Bonding and grounding conductors must not run parallel and in close proximity to S&C
circuit wiring. Wherever practicable, a minimum of 6” of separation is to be provided.
Bonding and grounding conductors may cross S&C circuit wiring (at approximately right
angles) without any specified minimum separation.

All exposed, non-current carrying metal parts of fixed equipment and equipment racks
must be bonded directly to the frame of the bungalow.    PVC Wiring Duct Systems

Approved PVC Wiring Duct Systems (herein called surface wire way) are to be used for
mechanical protection of signal equipment case wire. These must be mounted directly to
plywood walls, backboards, or to equipment racks. The surface wire way is to be of the
slotted-wall type, light grey in colour, complete with PVC cover.

Example: Panduit 3 x 3 or 4 x 4 inch.

Technical specifications                                                             21


The following clauses detail specific requirements for AC Power distribution within the
wayside housings.

•   All wiring and power distribution must conform to provincial and local electrical codes
    as appropriate for railroad applications.

•   All 6’ x 8’ and 8’ x 10’ housings are to be equipped with a load center equivalent to a
