73128 Potbridge 16 March 1990

As the late afternoon sun starts to disappear into high cloud, 73128 trundles along the up relief line at Potbridge on 16 March 1990 with a very mixed departmental working. Although it wouldn't make much difference with this small load, here it is running on the third rail, so has 1600 hp available, rather than the 600 hp if it was relying on its diesel engine.
