Two sets entered Departmental service: DMBS 51122 and DTCL 56300 became ADB975664 and ADB975637 for use as the "Stourton Saloon" – the Eastern Region General Manager's saloon – for which the class gained a small amount of "fame"; this pair were scrapped, in 1990, at Mayer-Newman's yard at Snailwell, in Cambridgeshire.

This vehicle survived the longest time on the national network, having been stored for some years in Basford Hall yard, out of use.

The final public appearance of ADB977191 was at the Crewe Works Open Day, on 21 May 2000, following which it was scrapped.

Following their withdrawal from service in East Anglia, in 1973, DMBSs 50341 and 51118, together with DTCLs 56097 and 56099, were acquired by the North Yorkshire Moors Railway, where they were painted in green and cream and given the numbers D10, D11, D20 and D21.

The National Railway Museum had intended to preserve 53355 (ex 50355), but a lack of space prevented this car, and the Class 105 coupled to it from being moved to York and they were vandalised beyond repair at Crewe.
