At the beginning of 1982, the CM&EE considered that development problems with the ATP-P project would mean that the introduction of APT-S, scheduled for 1988, would not happen because APT-P still required at least six more years to achieve an acceptable degree of reliability. Given this situation, a meeting of the BRB Railway Executive Group on 23 June 1982 laid out four options for the commercial introduction of APT as part an overall InterCity traction strategy, with the quickest solution being the APT-U option.
The APT-U consisted of two power cars with one at either end of the train and ten passenger cars, with a proposed increase to twelve vehicles to follow. Tilt was to be incorporated, but not articulation. The anticipation of the Board was for twenty trainsets to be completed for use mainly on the London to Manchester and Liverpool routes with selected operation to Glasgow. As this design incorporated proven equipment and dispensed with the APT-P's transfer gearbox and HK braking, it was envisaged that service operation could begin before 1989.
In mid-1984, TS Sc48204 was withdrawn from Set 370 004 and sent to the Engineering Development Unit (EDU) at Derby RTC for conversion to an APT-U test vehicle and extensive rebuilding of the underframe being undertaken in order to incorporate tilting double bogies based on the BT12 units. Following completion, some static testing was undertaken at Derby as well as dynamic testing on the WCML in an APT formation, where the coach was inserted between the TBF and NDM vehicles.Create a Later Fourteen Car Formation by adding the following SKUs (sold separately):
