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 overhead 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.

  • Work is expected to begin as early as Tuesday, May 21, 2019 for approximately six (6) months.
  • Work will be performed between the hours of 7 am and 7 pm, seven (7) days a week.
