Rehabilitation of Canadian Pacific’s (CP) Railway Infrastructure on the Westmount Subdivision

 

 

 

Project Objectives

AMT train on rail to downtown Montreal

The Westmount subdivision crosses the Ville-Marie borough, the City of Westmount, the Notre-Dame-de-Grâce borough and the City of Montreal West.

  • Improve the safety, efficiency and reliability of service for customers
  • Respect commuter train schedules
  • Enable the eventual expansion of commuter train service in this subdivision

 

Project Description

The project consists in:

  • Modernization of the signaling system
  • Extending the third track south all the way to the Montréal-Ouest station
  • Widening the Vendôme station platform to service the third track
  • Building an impact wall at the Grand Boulevard pedestrian overpass

Work Performed in 2012

  • Extension of the third track south all the way to the Montréal-Ouest station
    • Relocation of optical fiber: spring and summer 2012
    • Earthwork: spring and summer 2012

Work to Perform in 2013

  • Replacement ofthe railway signalling system with a latest-generation system
  • Construction of concrete bases for the six signal gantries
  • Installation of signal support gantries and other signalling elements
  • Earthwork - Vendôme section
  • Erection of an impact wall south of the future third track at the Grand Boulevard pedestrian overpass (with the addition of the third track to the south, a protective wall must be erected to comply with current railway regulations)

 

Work to Perform in 2014

  • Extension of the third track south along 4.8 km to the Montréal-Ouest station
  • Track laying work (fall 2013 to summer 2014)
  • Widening of the Vendôme station platform to service the third track (2014)
  • Installation of crossovers between tracks (2014)

 

Construction Schedule

Work began in mid-August and is being carried out from Thursday to Sunday, from 7 a.m. to 5 p.m. The work is first performed in the City of Westmount and then in the NDG/CDN borough. Work may be carried out simultaneously in one or two areas. Construction should be completed between now and December.

 

Work connected to the construction of an impact wall (in the NDG/CDN sector) will begin in mid-October and will be completed over the winter. Some types of work may be carried out during the day and others at night.

 

Mitigation Measures

In order to minimize the impact of work on citizens living near the railway track, mitigation measures will be implemented from the outset of the work. The following actions will be deployed:

  • Preparatory work will be carried out before the passage of the last trains.
  • In general, noisy construction work will be performed in the evenings and quieter work will be performed at night.

 

  • CP and the contractor will alert their staff on the right behaviours to adopt at night (reducing volume of radio telecommunications, keeping voices down, etc.).
  • Lighting will be limited to work zones.
  • Material will be delivered during the day, reducing truck traffic during evenings and overnight.
  • Noise levels and vibration will be monitored.
  • An acoustic barrier will be installed near the noisiest machines.

 

Project Background

Commuter trains from the Vaudreuil-Hudson, Saint-Jérôme and Candiac lines all run on CP’s railway infrastructures on the Westmount subdivision before converging at Lucien-L’Allier station. The Westmount subdivision is a 7.4 km section of track that stretches from the Montréal-Ouest station to Lucien-L’Allier station.

 

The configuration of railroad tracks and the state of railway signals have now outlived their usefulness. A single delayed or broken down train causes delays that cascade to all other departures across the three lines. The study carried out on this subdivision revealed that any additional service on this section of track would make the situation even more critical or possibly even unmanageable. Investments are therefore needed to improve the reliability of service currently offered to customers before the frequency of trains can be increased on this subdivision.

 

Inspections performed by CP and the AMT revealed that work is needed to ensure service reliability, maintain train speeds and consequently respect train schedules between the Lucien-L’Allier and Montréal-Ouest stations. This work will reduce ad hoc interventions by forestalling breakages that cause service disruptions.
