MEC film from steam days

Found this random video of various MEC scenes in the 40s(?)

Gold stars to folks who can figure out where some of the filmed locations are!

The first scene looks like Bangor Union Station. The interlocking tower looks like Royal Junction. The scenes with the trainmen walking along the top of the train I think is on the Lewistion Lower, then Brunswick yard.

Great footage Cowford! Could have used more of the soundtrack (Debussey?) which is a nice contrast to the neo Stuckey's cornball and finger picking guitar that permeates too many archival rr films.
