MR electric units

The Midland Railway experimented with electrification on its Heysham–Morecambe–Lancaster line in Lancashire, England. Electric trains started to run over this route in 1908, using the overhead 6.6 kV, 25 Hz AC electric supply installed and generated at the MR's own power station in Heysham.

The electric multiple units consisted of three driving motor coaches and six driving trailer coaches. Since the DM cars had a cab at each end, this allowed trains of one, two, or three cars to be formed.

No units have been preserved
