Scope:

Was a CSA withdrawn Standard.

 

Scope 1.1

This Standard applies to the overhead contact system and traction power supply to the locomotive, using a single-phase alternating supply at 25 or 50 kV nominal voltage, 60 Hz.

1.2 This Standard has been written primarily for use in the development of conventional railway freight and passenger services. However, the use of the Standard is recommended for development of special services, such as rapid transit, wherever possible.

1.3 This Standard covers design considerations in the following selected areas of railway electrification:

(a) insulation coordination and electrical clearance;
(b) vertical and horizontal clearances;
(c) overhead contact systems;
(d) interference with railway signalling circuits;
(e) interference with communication circuits;
(f) utility interface-unbalance and harmonics;
(g) grounding and bonding, and

(h) climate change adaptation considerations

 

 

Project need:

Currently there is a gap in the Canadian standards system in the area of railway / transit electrification. With railway electrification of public transit providing opportunity to decarbonise the transportation sector and further relieve congestion, this infrastructure is growing in importance to Canadian cities. Currently the railway industry is applying specifications and requirements for design, construction and maintenance from a variety of sources. Industry will benefit from the availability of standardized solutions addressing the Canadian environment, regulatory regime and operating conditions; including risks associated with climate change such as flooding/drought, ice storms, snow loading, high winds, wildfires, etc.
