The Class 121 and 122 `Bubble cars’ form part of the first generation of DMUs produced by British Rail to operate on branch lines and secondary routes. The Class 121 was built by Pressed Steel in 1960, 15 single power cars numbered W55020 to W55035 and 10 trailer cars numbered W56280 to W56289 were manufactured.

Until recently there were still two 121’s in service and eight are preserved. The Class 122’s was built by Gloucester RC&W in 1958. Twenty single powered cars numbered W55000 to W55019 and nine trailer cars numbered W56280 to W56289 were manufactured. All of the 122 fleet was removed from revenue earning service, however several remained in departmental use. Eight Class 122’s survive into preservation including W55001 at the East Lancashire Railway which was laser scanned to help produce the model.
