Metra contracts with Wabtec for Electronic Train Management System

November 7, 2006

WILMERDING, Pa. - Chicago commuter railroad Metra and Wabtec Railway Electronics have signed a contract for Wabtec to provide its Electronic Train Management System® to the regional commuter railroad. Under the contract, Wabtec will install ETMS on 24 locomotives and 24 passenger cars used on the Metra Rock Island line between Chicago and Joliet, Ill. Installation will begin in early 2007, with the ETMS-equipped locomotives and cars in revenue service in 2008. MotivePower, another Wabtec subsidiary, originally built some of the locomotives in 2003-04.

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 a 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.

The system could help avoid accidents such as one that killed two Metra passengers in September 2005 at 47th and Wentworth in Hyde Park on Metra's Rock Island line. The National Transportation Safety Board said the train was going 69 mph even though the speed limit on that section of track was 10 mph. The engineer might have missed a signal at 53rd Street, although he testified that he had all clear indications when he went past the signal. The NTSB report indicated the signals were working and were yellow over yellow - a sign for trains to reduce speed. The Wabtec system would have forced the train to slow down automatically. The 2005 derailment followed another in the same location two years earlier.

Hmm curious. There are what, ten or so other routes that will not have this system. The Rock has also recently had big speed limit signs installed along the line. Does Metra see their Rock engineers as being sub-par or something?

I didn't know RI had 24 locomotives assigned to the district, unless Metra plans to add some additional equipment...

100-104:5
202-204:3
206-208:3
406-410:5
412

17 locomotives at the moment.

Can't say one way or the other, but anytime there's two accidents on the same route at the same site two years apart, I'd say that's a strong indication of a problem. And with on-board fatalities involved in the second accident, it was obvious that something had to be done. Making RI the first route to be deployed with the new technology is only fitting, especially when you consider that the consensus regarding the cause of both accidents seemed to be the deadly combination of human carelessness with a signal system that, at least up to now, doesn't enforce penalty braking applications for speed limit infractions. ETMS would at least change that part of the equation...

Me neither. Must've been a typo. And if the Rock ever does get 24 locomotives assigned there, that would mean they'd be running trains on BNSF-like frequencies. Even though the schedule needs to be revised, it's unlikely the new schedule will quite approach those levels...
