Diesel Locomotive variety at Conisbrough and Mexborough

The Sheffield to Doncaster line at Conisbrough and Mexborough can produce quite a variety of traffic. Passenger services are run by Northern, Trans-Pennine and Cross-Country, and there is a good flow of freight trains plus light locos. In this video I have put together clips of 7 classes of diesel locomotives on the line, classes, 37, 47, 56, 60, 66, 69 and 70.
