Comments on: A pair of CN SW1200RS units from class GR-12f built in 1956 rush back to Toronto Yard with a van hop movement. The units are 1228 and 1237. The units may be from the same order, but there are many differences. 1228: small number board numbers; grey spark arresters; low CN symbol; low cab number. 1237: large number board numbers; silver spark arresters; high CN symbol; high cab number. Hard to believe this photo was taken 45 years ago. http://www.railpictures.ca The BEST Canadian photos on the Internet, eh?

Nice photo. By the looks of the dusting of snow being kicked up I’d say he getting along at track speed. Nice photo.
