In 1975 Bombardier teamed with Toronto's GO Transit to design a bi-level commuter coach capable of carrying 130 passengers. Two years later, the first of these cars went into service and GO Transit continues to have the largest fleet with over 300 cars.

In 1989, Tri-Rail, serving Miami, began service with leased GO cars and later bought 26 cars. That same year a set of GO equipment made a demonstration tour. The tour was a success as Southern California's Metrolink started service in 1992 and has the second largest fleet of 122 cars.
Since then, San Diego's Coaster, West Coast Express in Vancouver, BC., Altamont Commuter Express in California, Seattle's Sounder, and Trinity Railway Express serving Dallas and Fort Worth have all acquired fleets of the cars. In addition, two Sounder train sets have been leased to Virginia Railway Express.
