21:42 Arrival at mount pleasant deadheads back to union?
The last train to guelph probably deadheads back to union.
No. Due to the timing of CN's wayfreight to Kitchener, it was decided that this train would end its run at Guelph, and thus have lots of time to make its way to the Shirley Layover without having to worry about a schedule. If it needs to sit and wait for the CN crew to finish its work, it can.
