routes passing through Aston, including the Windsor Street branch, were electrified in 1966 as part of the London Midland Region's electrification programme. The actual energization of the line from Coventry to Walsall through Aston took place on 15 August 1966. In preparation for electrification, Aston's two mechanical signal boxes, Aston No. 1 and No. 2, were closed, semaphore signalling was replaced by multiple-aspect colour light signals and control transferred to the power signal box at Birmingham New Street. Electrification of the line to Sutton and Lichfield was completed in 1992 as part of the modernisation of the Cross-City Line. In 2017, control of the signalling at Aston was transferred to the West Midlands Signalling Centre at Saltley. Services Aston receives regular services on both the Cross-City Line, from Lichfield Trent Valley to Bromsgrove and Redditch and the Walsall Line, from Wolverhampton to Walsall via Birmingham New Street. On weekdays four services per hour call at Aston on the Cross-City Line in each direction. Services southbound terminate at either Bromsgrove and Redditch, with two per hour terminating at Bromsgrove and the other at Redditch. Northbound, there are two destinations on the Cross-City Line, which are Four Oaks and Lichfield Trent Valley. Two of the four services run the full length of the line from Bromsgrove to terminate at Lichfield Trent Valley, and the other two go as far as Four Oaks. On Sundays, two trains per hour run the full length of the line from Lichfield Trent Valley to Redditch in both directions, calling at Aston. The Walsall line is served by fewer trains: there are two per hour into Walsall on weekdays, which call at all stations from Birmingham New Street to Walsall, and one train to Wolverhampton per hour. Development of Train Services Early days In January 1858 there were eight trains from Aston (originating in Birmingham) to Wolverhampton via Bescot Junction and Willenhall, the first at 08:21 and the last at 21:11 on weekdays. In the opposite direction, on weekdays, nine trains from Wolverhampton arrived at Aston between 08:51 and 22:25. The Sunday service consisted of six trains in each direction. The timetable shows one "government" or Parliamentary train in each direction, running every day. Most trains provided through carriages to via and Lichfield, dividing at Bescot.
