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.
