The RCTS: then and now

摘要

IF ASKED to say which are the oldest diesel multiple units (DMUs) operating on the network it is likely the vast majority would pick out a'Pacer'-but the correct answer would be No. 150001, as the following excerpts from The Railway Observers of 1985 reveal. The now extinct Class 141s did predate the '150s', but in late-1984 it was advised two each of three-car units of Classes 150 and 151 were to be built with the intention to order 100 vehicles of one of the types. At the same time 50 Class 142s and 25'143s'were also mentioned.
