Nine London Underground 1983 model stock trains were decommissioned and abandoned in the South Harrow sidings in 1998 when the 96 model stock trains were introduced. The poor condition of the 83 train cars made it unsafe to haul out onto the network to a depot.

Nine London Underground 1983 model stock trains were decommissioned and abandoned in the South Harrow sidings in 1998 when the 96 model stock trains were introduced. The poor condition of the 83 train cars made it unsafe to haul out onto the network to a depot. Sonic Rail Services were contracted by the Station Works and Improvement Program (SWIP) of London Underground to remove the carriages from the South Harrow station sidings, with minimal disruption to the network and to undertake the necessary remedial repairs to the track.
