Belair railway line

The Belair railway line is a suburban rail commuter route in the city of Adelaide, South Australia, that runs from the Adelaide station to Belair in the Adelaide Hills via the Adelaide-Wolseley line.

History
The Adelaide-Wolseley line from Adelaide to Belair and Bridgewater opened in 1883. In 1919, a new alignment was built around Sleeps Hill as part of the duplication of the line. This involved a new double track tunnel being built to replace two tunnels and two viaducts. The new alignment was also 400 metres shorter. On 18 June 1928, the line was duplicated from Eden Hills to Blackwood and on to Belair on 24 June 1928.

Passenger services stopped beyond Belair on 23 September 1987. In 1995, the track used by Adelaide bound services was converted to standard gauge as part of the Adelaide to Melbourne standardisation project. The broad gauge passenger services south of Goodwood were thus restricted to one track with crossing loops located at Mitcham, Sleeps Hill, Eden Hills and Blackwood. At the same time, the stations at Millswood, Hawthorn and Clapham were closed to speed up services. Millswood was later reopened on 12 October 2014.

Re-sleepering and electrification
In 2008, the State Government announced a plan to rebuild the Belair line. This work saw the track removed, with the track bed and track renewed. Dual gauge sleepers were laid to allow for the line to be converted to standard gauge at a future date. Unlike other lines is not planned in the immediate future due to extra engineering work and complications with the standard gauge line. The line closed on 26 April 2009 and reopened on 23 August 2009 with buses replacing trains.

The Belair line was closed from 1 January 2013 to 14 July 2013 to allow for electrification of the line from Adelaide to Goodwood and construction of a grade separation at Goodwood Junction with relatively little work performed on the Belair line itself.

Route
All services are operated by Adelaide Metro's 3000 class railcars. Until June 2007, some services on weekends were operated by a 2000 class railcar modified to incorporate increased bike capacity. In 2005, trains ran the route every 30 minutes on weekdays (hourly after 7pm) and every 60 minutes on weekends and public holidays. From 2006, because of the single line, this was downgraded to every 36/24 minutes on weekdays.

The standard gauge track is owned by the Australian Rail Track Corporation and continues beyond Belair as the Adelaide-Wolseley railway line. The track is used by freight trains operated by Aurizon, Genesee & Wyoming Australia, Pacific National and SCT Logistics, and by the twice-weekly Overland service to Melbourne operated by Journey Beyond Rail Expeditions.
