Trough battery 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. The inside of this box was lined with shellac for insulation, and pairs of welded-together zinc and copper plates were laid out in this box, evenly spaced. The
Battery electric multiple unit Merseyrail Wirral Line and extend into the underground section of Liverpool's city centre. The line is diesel train operated unable to progress into the electric 3rd rail underground Birkenhead and Liverpool Merseyrail tunnels. The diesel operated line terminates at Bidston railway station in Birkenhead, with passengers having to change trains at Bidston to proceed onto the Merseyrail electric network. Network Rail proposed using dual battery powered/3rd rail pickup rolling stock without full electrification of the 27 mile long line, providing a cheaper method of increasing connectivity into the electrified underground sections of the Birkenhead and Liverpool Merseyrail Wirral Line.
