When coupled together for tandem working, the conversion of former Class 155 two-car sets into single-car Class 153s becomes apparent.
No. 153375 (right) has the original larger cab as built by British Leyland in the late 1980s.
That of No. 153371 (left) shows the smaller, more cramped layout built by Hunslet Barclay, at what used to be the non-driving end of a Class 155 vehicle, during its conversion in the early 1990s.
