On track in Chicago

Wabtec Railway Electronics has signed a contract to provide its Electronic Train Management System (ETMS) to Metra, the regional commuter railroad serving Chicago.



Under the contract, Wabtec will install ETMS on 24 locomotives and 24 passenger cars used on the Rock Island line, which makes up about 10 percent of Metra’s system. Installation will begin in early 2007, with the ETMS-equipped locomotives and cars entering revenue service by 2008.



With ETMS, movement-related information, such as authority limits, speed limits, signal aspects and work zones are passed through a digital communications network to an onboard computer. The onboard computer, with location information provided via the global positioning system, will automatically initiate enforcement braking if the engineer fails to respond appropriately to movement and speed limit information.


In addition, a computer screen inside the locomotive cab displays the authority limits, speed limits and work zones, as well as a moving map detailing grade, curvature and track topology.
