Battery electric multiple unit Line from Ellesmere Port to Helsby interchange station and the Northern Line from Ormskirk to Preston interchange station. Vivarail is the first company to manufacture battery electric trains in the UK in the modern era. Their Class 230 is converted from redundant London Underground D-Stock trains and the second demonstrator unit, the two-car 230002, has been fitted for battery power in contrast to the diesel-electric power of the earlier 230001 demonstrator unit. Vivarail claim that a ten-minute charge gives a range of 50 miles. Power is provided by two lithium-ion batteries per car giving four per train, providing 106kWh, with
