It was previously a state-owned corporation known as the Transport Asset Holding Entity of New South Wales (TAHE) which was established by converting and renaming RailCorp on 1 July 2020.

[5] Like its predecessor RailCorp, the TAHE/TAM holds rail property assets, rolling stock and rail infrastructure in the Sydney metropolitan area and limited country locations in the state and it makes these assets available to Sydney Trains and NSW TrainLink for their operations.

[6] A sister entity, the Residual Transport Corporation (RTC), which was formed in July 2017, owns assets not suitable for TAHE ownership.

[13] The Financial Review report stated: "Faced with the new accounting standards, PwC instead recommended either the whole TfNSW portfolio be fully corporatised or the TAHE proposal be dropped."
