The largest ELR class was a series of outside-frame 2-4-0s with cylinders and driving wheels. Some may have originated as 2-2-2s, and some were later rebuilt as 2-4-0 tank engines. One was rebuilt as a 2-4-0 saddle tank engine. These were among the last locomotives to be built in Bury. Other manufacturers to supply the ELR were Sharp, Roberts and Company, Stothert, Slaughter and Company, and Beyer, Peacock and Company. The ELR livery for passenger locomotives was dark green with red brown frames, and polished domes and safety valves.
