Trough battery spaces between the plates (the troughs) were filled with dilute sulfuric acid. So long as the box was not knocked about, there was no risk of electrolyte spillage. Trough battery The trough battery was a variant of Alessandro Volta's Voltaic Pile and was invented by William Cruickshank c. 1800. Volta's battery consisted of brine-soaked pieces of cloth sandwiched between zinc and copper discs, piled in a stack. This resulted in electrolyte leakage as the weight of the discs squeezed the electrolyte out of the cloth. Cruickshank solved this problem by laying the battery on its side in a rectangular box.
Battery electric multiple unit an expected life of seven years for the batteries. The train is due to run on the national network in summer 2018. In 2017, Vivarail battery trains were being considered for use on the Valley Lines network in South Wales. The trains would be battery powered, capable of being recharged via 25 kV OHLE. The Edison-Beach battery railcar was developed by Thomas Edison and Ralph H. Beach. The latter headed the "Railway Storage Battery Car Company" and the "Electric Car & Locomotive Corp". Car No. 105 of the Alaska Railroad was an Edison-Beach car, and examples operated on the Central
