end of SC50874 was severely damaged, and was never repaired, with the vehicle officially withdrawn 16/2/76. In early hours of 3 August 1983, Set 116391 was being returned from a Works visit, conveyed on the rear of a parcels train from London, when it derailed and caught fire at Portobello on the East Coast Main Line. As the vehicles were asbestos contaminated the unit was withdrawn in October 1983 and eventually disposed of by burial in Paterson's Tip, Mount Vernon in July 1984. Pacer substitution Several units were allocated to Heaton TMD in the late 1980s to carry out Pacer replacement services during the latter's troubled introduction period. During this time, the individual cars were often mixed into hybrid sets with, for example, class 119 vehicles. Services worked included Bishop Auckland to Saltburn. Parcels use Three units were converted to carry parcels traffic and reclassified as Class 130, though the individual coaches were not renumbered. The units involved were: 50819 + 50872 50862 + 50915 51137 + 51150 W50915 reverted to standard Class 116 configuration in 1977 and transferred to Tyseley To provide extra capacity, they worked with modified General Utility Vans (GUV) as centre trailers.
