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 Vermont Railway running between Millers Falls, Northfield and West Townshend. A notable feature of the Edison-Beach cars was the Beach drive system. Each wheel was mounted on ball bearings on a dead axle and was driven by an individual traction motor through gearing. Battery electric multiple unit A battery electric multiple unit, battery electric railcar or accumulator railcar is an electrically driven multiple unit or railcar whose energy is derived from rechargeable batteries that drive its traction motors. The main advantage of these vehicles is that they do not use fossil fuels like coal or diesel fuel, emit no exhaust
