CN & CP in Southern Ontario

In clip one a heavy CP northbound requires pushers as it tackles the Niagara Escarpment on the way to Guelph Jct.
Clip two features a meet between an eastbound local out of Hamilton and a westbound road freight diverging off the Oakville Sub onto the Dundas Sub at Bayview Jct.
Clip three is that same westbound road freight cresting the Niagara Escarpment at Copetown. A Grand Trunk GP38 is the second unit.
Clip four is CN's Roadrailer starting down the escarpment at Copetown, just east of the previous sequence.
