About the Train

Electric Multiple Unit (EMU) Information

For more information on the difference between light rail and commuter rail please visit here.

Commuter Rail Fact Sheet

The project evaluated various rail technologies, and the preferred technology for the corridor is Electric Multiple Unit (EMU). The EMU is heavier than a light rail vehicle, but operates in the same way. This vehicle will be powered via an overhead contact system (OCS) similar to that provided for the existing Light Rail Transit (LRT) lines.  Facilities to distribute power to the trains, known as paralleling stations, will be provided at two to four locations along the project alignment, typically within station areas.

The factors that were considered include:
  1. Ability to integrate into the FasTracks system
  2. Capital and operating costs
  3. Operations and maintenance requirements
  4. Environmental impacts
  5. Public input
