British Rail Class 304

The British Rail Class 304 (Originally classed as AM4) were AC electric multiple units designed and produced at British Rail's (BR) Wolverton Works. The Class 304 was produced for BR's new electric suburban services, enabled by the first phases of the West Coast Main Line electrification between Crewe and Manchester/Liverpool/Rugby. The units conformed to the 1959-design for alternating current (AC) electrical multiple units, and were externally very similar to the Class 305, Class 308 and the 1,200 V direct current (DC) Class 504 units.
