CONSTRUCTION BEGINS AT TPSS 10 (Traction Power Substation)

What Work is Taking Place?

As part of continued support of the future surface alignment for the Eglinton Crosstown LRT, crews will be excavating and building a foundation for the Traction Power Substation 10 (TPSS) that will power the Eglinton Crosstown Light Rail Transit (ECLRT). The work will take place on the north west corner at the Eglinton Avenue East and Victoria Park Avenue intersection.


What is a traction power substation?

  • A TPSS is a steel building similar in size to a shipping container.
  • It provides electrical power to the LRT via the overheard catenary system used to power the trains. A TPSS converts electricity from the local power source to the levels needed by the vehicles.
  •  A TPSS is a safe structure that will not introduce any new risk to the community in which it is constructed.
  • All TPSS structures are air-conditioned and therefore emit a low humming noise, similar to a residential air conditioner.

Hours of Work

  • Work will occur late June, 2019 to early August, 2019
  • Work will be performed between the hours of 7 am and 11 pm, seven (7) days a week.
  • Note: Unexpected circumstances (weather, equipment failure, etc.) may also change the above interruption plans or prolong the interruption. If this occurs, we will endeavor to provide reasonable notice. 
  • Excavation and construction of the foundation will continue for approximately five (5) weeks.


 What to Expect

  • Excavation and construction of foundation for TPSS 10 at the north west corner of Eglinton Avenue East and Victoria Park Avenue intersection.
  • Current lane reductions in place for road widening and reconstruction will be maintained. Construction activities will take place away from the roadway and sidewalks.
