Parsons has been appointed by Chicago’s commuter rail operator to install its positive train control (PTC) system on Metra trains.
Parsons role will include supplying and fitting a train management system that is interoperable with 12 other rail systems.
Chicago has been described as presenting the most complex challenge for PTC in the whole country.
In 2008, the Rail Safety Improvement Act made it mandatory for all passenger railways to have some kind of PTC system in place by December 31, 2015.
US authority the Federal Railroad Administration (FRA) have now admitted that most of the country’s rail routes will miss that deadline.
Parsons has already supplied PTC systems to several other US networks, including Metrolink, Amtrak and Caltrain.
