One of the two "heritage" units (along with 5001), it was repainted in British Rail blue in the early 1990s and survived until the end of EPB workings in 1995. After spending several years in storage, in 1999 the unit was split, with three vehicles going to the Northamptonshire Ironstone Railway Trust and one intermediate trailer vehicle to the Electric Railway Museum, Warwickshire near Coventry. Class pioneer 5001 was also stored at Kineton Ministry of Defence base following withdrawal in 1995 but no buyer could be found and the unit was stripped and sold for scrap in 2004. Only three vehicles remain at the Northamptonshire Ironstone Railway, with Trailer 15354 having been moved from now-closed Electric Railway Museum to the 1:1 Collection Building at Margate, as a donor/spares vehicle for the 4SUB unit 4732.
