Photograph by Chris Hogg of railway workers electrifying the East Coast Main Line. They are erecting catenary wires, which carry the current to power electric locomotives. Construction work on this section of the line was contracted out to Balfour Beatty. The East Coast Main Line electrification was completed in 1991, over 60 years after the North Eastern Railway first proposed using electricity. Electrification requires big capital investment, but delivers a very cheap, fast train service. Some railway insiders are already asking what will happen when the wires need replacing on the East Coast Main Line which is one of the main railway routes between England and Scotland.
