Not sure of the exact times of operations, but several GMD1s have been working in the Hamilton area over the past while. Saw three of them as I drove by Aldershot on Friday, March 15 at about 1700 (two on one train, one MUed with a Geep). They seem to work Train 551 Oakville-Aldershot, and on some transfers to Hamilton (555?). Earlier in the day, they can be seen working the west end of Oakville yard.
