The TF vehicles were late downgraded to TC vehicles, and later the TCs were downgraded to TSs. All vehicle types had toilets (L).
The original order for the vehicles was for twenty-two DMBSs, twenty-two DMSs, and twenty-two centre cars. Later, after the numbers had been allocated, one centre-car was changed to an additional DMS. As the numbers either side had already been allocated to other vehicles, the extra DMS was gived the out of sequence number 50936 (left free by a change in Class 108 orders) and left 59401 unused.
The two buffet-cars were a later order.
