The first of Direct Rail Services class 88 electro-diesels has been delivered to the operator’s depot in Carlisle. The class 88 is the first 25kV AC electro-diesel to run in Britain, and like the DC class 73s from the 1960s is intended to be used as a electric locomotive with “last mile” capability enabling it to reach freight terminals off the electrified network. It’s now set to undergo an eight-week testing program.
As a tester I’d love to know more about the test programme. What’s involved in testing a new design of locomotive?
