The Rapido Trains GMD F7B is based on Canadian-built locomotives constructed for Canadian Pacific by the General Motors Diesel Division in London, Ontario. Built between April 1951 and May 1952, many of the fleet continued in regular revenue service on CP into 1983 and those sold to VIA lasting into the early 1990s.
 
This model was built using original EMD-GMD blueprints and field measurements to ensure accuracy and includes correct roadname-appropriate detailing. Other features of the model include separately applied metal details, etched-metal grilles and metal magnetic knuckle couplers.
