Pacific Great Eastern 580 > British Columbia Railway 580
Montreal Locomotive Works built 129 1600-hp RS10’s, all for Canadian railroads. Only eight went to the Pacific Great Eastern, all in a single order. This was essentially an RS3 in a modernized carbody, with a 12-cylinder turbocharged 244G engine. In April, 1956, generator excitation changed from conventional to static mid-way through production of a Canadian Pacific order. All production from that point on was known as RS10S. CP 8568 was the final RS10 and CP 8569 started the RS10S model.
The Pacific Great Eastern became the British Columbia Railway on February 27, 1972, and this unit kept the same number under the new company. It was retired and scrapped in 1986.
