The line was built between 1863 and 1865 as the Rutherglen and Coatbridge Railway, part of the Caledonian Railway. It opened to goods traffic (mainly coal and iron) in September 1865 and to passengers in August 1866. It has been in continuous operation ever since. Stations in the first service on the line were at Carmyle, Broomhouse (now Mount Vernon), Baillieston, Langloan and Whifflet High Level (until 1964). Passenger services ceased in November 1966 following the Beeching Axe (latterly running to Coatbridge Central). Between 1972 and 1974 period scheduled passenger trains between Glasgow Central and Perth used the route. For the following twenty years, the route was only used for freight and diverted passenger services. However the line reopened by British Rail to scheduled passenger services with intermediate stations on 4 October 1993, running to the newly built station at Whifflet rather than Coatbridge Central as previously.
The modern line currently serves seven stations. It connects parts of south east Glasgow, Bargeddie and Coatbridge to Glasgow city centre. Between Glasgow Central and Rutherglen, the line shares the same track as the West Coast Main Line (and is hence electrified) before branching off in a north easterly direction towards Coatbridge (this section is now electrified).
The route is operated by Abellio ScotRail.
2009 service pattern
Trains operated at a half-hour frequency. All services were scheduled to run as two car trains only, although four carriage services were technically possible. Services were operated using Class 158 diesel multiple units and the occasional Class 156 DMU. Three trains operated on this route during the day, usually remaining dedicated on this service throughout the day.
From December 2014
In late 2014, the Whifflet Line electrification was commissioned and from 14 December 2014 the service was incorporated into the Argyle Line. At the same time an all year round Sunday service commenced.
In 2006, Network Rail announced tentative proposals to electrify the Rutherglen - Whifflet section, as part of a £1.4bn upgrade to Scotland's railways. The main benefits of this scheme were to provide an enhanced frequency for the Whifflet to central Glasgow routes and to provide an electric diversionary path for long distance WCML services. The new timetable came into operation on 14 December 2014, the Whifflet Line has been added to the Argyle Line system with services through Glasgow Central Low Level to the western suburbs.
