Test Car 3

Construction of the new LMS Dynamometer Car No:3 M45049 commenced at Derby C&W Works shortly before the outbreak of war in 1939, but it was not completed until a decade later, soon after the formation of British Railways in January 1948.

Initial trial runs were made in late April 1949 and it ultimately made 1,086 scheduled test runs between May 1949 and July 1975, covering an estimated 147,616 miles. Although originally designed to test steam locomotives, in the event it was also employed to evaluate diesel and electric locomotives and also the Prototype High Speed Train on the East Coast Main Line in June 1973.

During its working life this vehicle has carried several liveries, i.e. BR 'blood and custard' , BR maroon and latterly the BR Research Department 'Red and Blue'. Restored in 1979 it has been lettered LMS in recognition of its origins although it was not actually completed until after Nationalisation in 1947.

It is now part of the National Collection and was cosmetically restored at Barrow Hill.

In June 2011 the vehicle moved to the MRC, Butterley where it is housed in the museum at Swanwick Jcn. It is intended to restore the vehicle.
