Canadian Pacific F9B No. 1900 is providing more power to a passenger train at Banff, Alberta, on October 1, 2010. The F9B looks very similar to a F7B, but unlike the earlier model, No. 1900 has the F9-era Farr stainless-steel vertical grills running along the roofline. Later railroad modifications include replacing the center porthole with a set of louvers to aid in engine room cooling.
