METROLINK PTC PROJECT

Project Description

Positive Train Control (PTC) is a predictive collision avoidance technology that can stop a train before an accident occurs. Metrolink’s PTC project includes the installation of on-board PTC equipment on 57 cab cars and 52 locomotives, installation of stop enforcement systems at 476 wayside signals, and implementation of a six-county specialized communication network to link the wayside signals, trains, and centralized dispatch office. The Metrolink commuter rail system is one of the largest and most complex regional commuter rail systems in the nation.

Scope of Services

One of the critical tasks for this project is to inspect and analyze the entire Metrolink commuter rail network to verify operational parameters related to track, signal, and timetable. After the inspection and engineering analysis, RSE staff prepared track plans and profile drawings, track charts, and a track infrastructure database to facilitate the implementation of PTC. The work also involved coordination with major stakeholders including Union Pacific Railroad and BNSF to assure design compatibility and interoperability of the PTC database.
