RailCorp

Rail Corporation New South Wales (RailCorp) was an agency of the Government of New South Wales, Australia, established in 2004 pursuant to the Transport Administration Act 1988. It was a division under the control of Transport for NSW, following the latter's establishment in 2011. On 20 June 2020, RailCorp was disbanded with its functions taken over by Transport Asset Holding Entity.

RailCorp held rail property assets, rolling stock and rail infrastructure in the Sydney metropolitan area and limited country locations in the state, and made those assets available to Sydney Trains and NSW TrainLink for their operations. It also managed the government's contract with the Airport Link Company.

Until 2013, RailCorp also operated passenger train services in New South Wales under the brand CityRail, and maintained rail infrastructure within the New South Wales Metropolitan Rail Area. From July 2013, operation and maintenance functions were transferred to the newly created Sydney Trains and NSW TrainLink agencies, which were also subsidiaries of RailCorp, leaving RailCorp as an asset owner. In July 2017, Sydney Trains and NSW Trains ceased to be subsidiaries of RailCorp and became standalone independent agencies.
