The British Rail Class 122 diesel mechanical multiple units were built by Gloucester RC&W in 1958. Twenty single-car, double-ended driving motor vehicles, nicknamed "Bubble Cars", were built, numbered
Class 122, no. 55006, at Bewdley on the Severn Valley Railway 2004, whilst taking part in the Railcar 50 event. This unit is painted in the second version of BR Green livery, and is preserved on the Ecclesbourne Valley Railway.
At Stourbridge Junction, trains arrive and depart from platform 1, which is dedicated to the branch. After departure, the branch peels away from the main line, as seen in the left of this photo.
