153304 approaching Manningtree from the Colchester direction.
These units were originally built as two-car Class 155 units by British Leyland from 1987–88, but were converted by Hunslet-Barclay at Kilmarnock from 1991-92. The layout of the original non-cab ends was different from the original cab end, so the ends are noticeably distinct, and the vehicles are not symmetrical.
Their maximum speed is 75 mph (121 km/h) and suited for working less popular local services such as the London Midland service from Coventry to Nuneaton and the Heart of Wales Line. They are fitted with standard BSI auto-couplers and are therefore able to work in tandem with other multiple units fitted with the same coupler, including Class 150, Class 156 and Class 158 units as well as newer units like the Class 170 DMU.
