What is LYR electric units?
The [[Lancashire and Yorkshire Railway]] (L&YR) [[Railway electrification system|electrified]] urban railway lines in [[Liverpool]] and [[Manchester]] in order to improve the service offered against the competition being put up by new electric [[tram]]s. ==Liverpool== ===Liverpool to Southport=== The line between Liverpool and [[Southport]] began using [[electric multiple unit]]s (EMUs) on 22 March 1904. Power was supplied from a [[third rail]] at 625 [[Volt]]s [[direct current]]. ===Liverpool Overhead Railway=== Connections were built with the [[Liverpool Overhead Railway]] (LOR) at Seaforth & Litherland railway station to a new station beside LOR's Seaforth Sands station. Also from the North Mersey Branch route to [[Aintree]]. From 2 July 1905 LOR trains began to run through to Seaforth and Litherland. In 1906 the L&YR electrified the line to Aintree. ===Liverpool to Ormskirk=== Electrification to [[Ormskirk]] was completed in 1913. ==Manchester== ===Bury to Holcombe Brook=== From 1913 an experimental electric service operated between [[Bury]] and Holcombe Brook. The equipment was provided by Dick, Kerr & Co. of Preston, which was developing its products for export. The system used was 3,500 [[Volt]]s [[Direct current|DC]] from [[overhead lines]]. In 1918 the line was converted to the 1,200 V DC system chosen for the Manchester to Bury line. ===Manchester to Bury=== After the Holcombe Brook service, the L&YR decided to electrify the [[Manchester]] to [[Bury]] line. The system used was 1,200 V DC from a side-contact [[third rail]]. The purpose of this unusual arrangement was to prevent the service being affected by ice forming on the live rail. Sixty-six cars were built at Newton Heath works. The electrical equipment was supplied by Dick, Kerr & Co. The first public services ran on 17 April 1916, {{British Rail EMU}} {{transport-stub}} [[Category:British Rail electric multiple units|LYR]]
