A bill to build an extension, designed by Thomas Brassey, to Stockport was authorised on 4 August 1853 also renamed the railway company to the Warrington and Stockport Railway.
Opening
The Warrington and Stockport Railway was opened on 1 November 1853 from a temporary station at Wilderspool in Warrington to a station at Altrincham which later became Broadheath. Delays in the delivery of iron work for the bridges over the Mersey and Bridgewater Canal meant that the line was initially isolated from the rest of the railway network. The line was opened throughout from 1 May 1854 although passenger trains terminated at Broadheath until the W&SR and MSJAR could agree on charges for passengers travelling beyond there to Manchester via Timperley. A link with Stockport was achieved when the Stockport, Timperley and Altrincham Junction Railway opened its line on 1 February 1866 from Broadheath Junction on the W&SR to Skelton Junction on the newly opened line from Deansgate Junction to Stockport. The LNWR operated the line from opening and on 1 January 1861 bought it. On 9 July 1893 the line was re-routed to allow for the Manchester Ship Canal, which would open in 1894, the canal being crossed by the high level Latchford Viaduct.
Closure
Passenger trainson the line ended on 10 September 1962. The line to the east of Latchford closed completely on 7 July 1985. The line was still busy at this time but extensive repairs would have been needed to the Latchford Viaduct for continued operation – these were deemed not to be economically justifiable given that the remaining freight traffic could be diverted via alternative routes and there was no desire to extend the Manchester tram system to Warrington. The trackbed between Latchford and Broadheath now forms part of the Trans Pennine Trail. Current plans for HS2 show it may cross the line between Heatley and Carr Green. In March 2015 a planning application was submitted to build up to 280 homes on the former route in Latchford. This would involve levelling the railway embankment to the west of Latchford viaduct. However as of 2020, nothing has been approved nor planned to continue due to the line being protected by the council. In August 2019, the town council announced they were looking to build a mass transit network which would involve crossing the canal and have identified but yet to confirm it will go ahead. The line at Latchford. They also have announced in their proposal that any disused rail corridor in the borough is protected from development so it may be used again for either rail or different transport.
