New as D1944 from Brush, Loughborough in June 1966. Renumbered to 47501 from February 1974. Stored by EWS in April 1999, withdrawn in April 2001. In October 2002 acquired by DRS and passed through Glasgow Works returning to traffic in September 2003 after overhaul and twin-tank modification.
It is said that 47802 may now be on hit-list at DRS as it is at same design level as 47501.
