Project Description 

PNR RailWorks performs daily track and signal maintenance on 246 miles of GO Transit track to Class 6 standards and speeds up to 95 mph. GO Transit is the regional public transit service for the Greater Toronto and Hamilton Area, with routes extending to communities across the Greater Golden Horseshoe.  

Project Scope 

PNR RailWorks Signals & Communications (S&C) crews are imbedded with GO Transit operations staff to perform a range of maintenance duties on 246 miles of GO Transit track  All work is performed in conjunction with CN dispatching and Bombardier/CN/CP/VIA Rail train crews while train operations are underway on the rail lines.

In addition to maintaining the Centralized Traffic Control (CTC) system along the line, S&C crews also maintain the following infrastructure:

  • 231 bungalow and cases
  • 117 public crossings
  • 328 signals
  • 207 power switch machines
  • 158 switch clearing devices
  • 61 signal bridges
  • 5 layover sites/storage yards
  • Associated communication and power systems 


S&C crews are currently implementing the RailDOCS asset management tool to manage inspection and maintenance work performed in the field.  RailDOCS details the model and serial numbers of all signal equipment as well as their maintenance history. It also specifies maintenance requirements to help crews prioritize work and ensure it is performed on schedule.  A valuable auditing tool, RailDOCS also helps to improve communications between GO Transit and PNR RailWorks. .

In addition to these responsibilities, PNR RailWorks collaborates with GO Transit on the status of track and signal infrastructure priorities and advises on longer-term capital expenditures.
