Content: two were on hire at Corus Scunthorpe (nos. 81 and 82). Over a ten-year period, concluding in 2019, a number of class 20s from HNRC were employed to deliver new S-Stock from Bombardier Transportation at Derby Litchurch Lane Works, to London Underground at Neasden depot or West Ruislip depot, for commissioning. Subsequently, immediately after the completion of deliveries, modification of these units (addition of equipment for automatic signalling) was required and they were returned to Derby in the same manner. Formation of the trains usually consisted of a pair of Class 20s, two barrier wagons, the LU S-Stock set, two barrier wagons and a dead-in-tow pair of Class 20s at the rear. Sub-classes
