The story
The NSWGR built its entire route network to standard gauge. Its first line, also the first railway of New South Wales, was the railway line from Sydney to Parramatta (today: Granville railway station) completed in 1855.
The agency was managed by a range of different commission structures between 1857 and 1932, which reported to either the Minister for Public Works or the Minister for Transport.
The inaugural Chief Commissioner was Ben Martindale and, following the enactment of the Government Railway Act, 1858 (NSW) he became Commissioner of Railways. John Rae succeeded Martindale in 1861, and in 1877 Charles Goodchap was appointed Commissioner. The Government Railway Act, 1888 (NSW) set up a corporate body of three railway commissioners to manage the railways and remove them from political influence, resulting in the resignation of Goodchap.
This Board of Railway Commissioners of New South Wales was in place from 22 October 1888 to 4 April 1907, and was replaced by a sole Chief Commissioner of Railways and Tramways until 22 March 1932, when a panel arrangement was restored for a period of nine months, with the Transport Commissioners of New South Wales. On 29 December 1932, the Department of Railways New South Wales was established and Thomas Joseph Hartigan was appointed Commissioner for Railways replacing the functions of the Chief Transport Commissioner. The Department of Railways New South Wales become the official name of the railway and was used on most documentation (drawings & other paperwork), the NSWGR title was still used periodically on public documentation such as advertising and timetables. This continued until the creation of the Public Transport Commission on 20 October 1972. The last Commissioner for Railways was Neil McCusker.
