Siemens ATP for Trillium Line South Extension

Written by William C. Vantuono, Editor-in-Chief

SNC Lavalin wholly owned subsidiary TransitNEXT has selected Siemens Mobility to provide the signaling and train control system for Ottawa’s 10-mile, eight-station Trillium Line South Extension project. The contract also includes updating the existing Trillium Line’s signaling system and installing ATP (Automatic Train Protection) technology on the entire network. ATP “will be increasingly important, given the higher ridership levels expected with the Trillium Line’s new South Extension and the connection to Ottawa’s Macdonald-Cartier International Airport,” Siemens noted. The project is expected to be completed in 2022.
