The Brush Type 4, or Class 47 as it was later known, truly was the all-purpose workhorse of the modernisation era. At home on everything from the humble pick-up freight to the most tightly-timed express, these 2,750hp locomotives once dominated the railway scene and could be seen almost everywhere on the network.
