Communications-Based Train Control (CBTC) System
SelTrac™ CBTC is the Confederation Line’s state of the art railway traffic control system that is used to optimize system capacity on the railway. This is achieved by continuously monitoring the location, speed and direction of all trains operating on the guideway to reduce the time interval between them.

SelTrac™ CBTC can control the behavior of the train at all times. It makes use of the telecommunication between the Confederation Line’s trains and track equipment for safe and efficient railway traffic management.
