Metrolink Positive Train Control (PTC) and Data Model Project

Under this contract, RSE is providing a wide range of services including engineering analysis, PTC data collection, track and signal infrastructure inventory, system wide mapping, and PTC database development for over 250 route miles covering 5 counties in Southern California. One of the main tasks for this project is to inspect and analyze the entire Metrolink commuter rail network to verify operational parameters related to track, signal, and time table. After the inspection and engineering analysis, RSE staff prepared track plan and profile drawings, track charts, and 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.

Postive Train Control System

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.

Under this contract, RSE is working closely with LTK, RF Networks, and Xorail to provide overall design for the PTC system. The engineering tasks include engineering analysis, PTC database development, PTC data collection, track and signal infrastructure inventory, design & supply of on-board and PTC Back Office Server sub-systems, systems engineering, systems design, equipment and systems testing, and systems commissioning.

The PTC back office server (BOS) interfaces to a new Computer-Aided Dispatching (CAD) system and system wide mapping for approximately 388 route miles covering six counties in Southern California. Xorail is supporting the build-out of the PTC system including the BOS and CAD systems. Xorail-managed Services include: Back Office Server, Training Simulator, Locomotive installation and training, and PM and local systems engineering support. LTK provides support for vehicle on-board system installation and the local motive/ cab car simulation module. RF Networks provides engineering for the design and implementation of the communications system.

RSE provides inspection and engineering analysis for the entire Metrolink commuter rail network to verify operational parameters related to tracks and signals. After the inspection and engineering analysis, RSE staff prepared track plan and profile drawings, track charts, and a track infrastructure database to facilitate the implementation of PTC and training Metrolink staff. The work also involved coordination with major stakeholders including the Union Pacific Railroad and the Burlington Northern Santa Fe Railway to assure design compatibility and interoperability of the PTC system.
