Having completed their work in the south yard - for now at least - 4130 and 4141 prepare to move their train across the mains to the north yard where more work awaits.
A little unusual - for me at least - is seeing a CP freight in Oakville. CP 8605 leading multimarked SD40-2 6068 slows for signal 203 on the CN Oakville Sub at the west end of Oakville Yard.
