Some units were disbanded during mid 1960's to provide stock for the class 206 'Tadpole' Units and to reform other 'Hastings Sets' after the Hither Green rail crash. Set 1002 was later reformed to its original formation in 1979, but set 1004 was reformed with only its original power cars and some trailers from sister class 202 and 203 Hasting Sets. Set 1003 was reformed only for the last few months of Hasting DEMU service after its power cars were used for spares, again with none of its original trailers. Set 2007 also suffered a reformation in 1969 but it remained as a full six coach set until withdrawal in 1986.
Most units were withdrawn and scrapped following electrification of the route in 1986. However, one complete unit, no. 1001, was preserved by Hastings Diesels Ltd., which is based at St Leonards-on-Sea. Vehicle no. 60000 has been named Hastings after the town which it previously worked to. This was mainline operational from the unit's revival in 1996 to 2006, but this motor coach was not prioritised when it needed fitting with Central Door Locking (CDL) & On-Train Monitoring Recorders (OTMR). 60000 also needed an overhaul to its bodywork and because of the costs involved, both financial and manpower, this work has not been carried out yet, which means it is currently in storage at St Leonards Depot. The two mainline certified motor coaches that are currently in use on the Hastings Diesel and are fitted with CDL and OTMR are 60116 Mountfield (certified in 2003) and 60118 Tunbridge Wells (certified in 1996). It operates several mainline railtours a year, starting from Hastings and going to various destinations across the South of England.
The Hastings Diesel Limited own thirteen non-mainline certified vehicles which are in various states of readiness. Two of these are: part restored trailer 60527 and unrestored motor coach 60001, which formed the motive power for the original unit 1001. They have said that there will be no serious work done to 60001 until work to motor coach 60019 is completed, as this one apparently needs less work done to it: which is cheaper and returning 60000 Hastings to front line service is also finished.
