Lifecycle of a project - Testing & pre-operations

Testing & pre-operations: Starts a year to six months before service begins

From the time construction wraps-up (and sometimes even before) to when service begins, work is underway to make sure that the project is ready and that the public is ready for it. The pre-revenue testing phase includes a safety certification process. Passengers can't begin riding until the service is certified.

Activities include:

  • Various simulations that make sure that communications, safety and emergency and other systems are running and working together.
  • Intersection signals, crossing gates and pedestrian signals are checked. Trains begin running without passengers to help pedestrians, bikers and drivers learn how to travel safely with trains.
