We're in the process of a locomotive swap between 313 (Cochrane to Kapuskasing) and 516 (Hearst to Kapuskasing) at Kapuskasing March 11th. GP38-2 1804 (on the left) is uncoupled from 1800 (in the background) and is being run up Kap's centre lead in order to be m.u.'d with GP38-2 1805. 1801 (sitting on the main) has already been wyed and will proceed to back up to be coupled with 1800. 1804 will then be run to Cochrane for inspections and servicing.
