Conversion

They were withdrawn from normal service in April/May 1939 and subsequently converted to mobile power units, emerging in their new guise as MPU2/MPU1 in May 1940/October 1940 respectively. MPU2 (7055) was later allocated to the Eastern Region of British Railways, where it was identified as number 953 in their departmental vehicle series.

Scrapping

They were scrapped in February 1964/January 1956 respectively, though due to administrative errors, the disposal of 953 (7055) was not recorded and it was initially allocated number 968004 in the new departmental locomotive series introduced in 1968.
