The cabs of the locomotive were converted from
Western Region right-hand drive to the standard British Rail left-hand drive arrangement. The rebuilt locomotive was completed and ready for trials in October 1958. It retained its original BR black livery, with a silver stripe around the middle of the body and silver numbers.

Once the production locomotives (
Class 81 onwards) were in service, E2001 was no longer required. It was put into store at the end of 1961, and lasted for over ten years at various locations. It was officially withdrawn in April 1968 and scrapped in November 1972 at
J Cashmore in Great Bridge.
Models
E1000/E2001 is being made as a kit and a ready-to-run model in OO gauge by Silver Fox Models.
