[1] The setting up of an organisation to manage and operate locomotive 3801 was first formalised in March 1984, the State Rail Authority exchanged correspondence.

Its stated aim was "to exhibit with pride and enthusiasm to the people of NSW the masterful preservation of a piece of their Locomotive History ... as a living, mobile, historical work".

[7] At the conclusion of the 20-year lease covering the operation of locomotive 3801, the New South Wales Rail Transport Museum decided not to offer a renewal with 3801 departing in November 2006.

[7][8] To provide an operational base for 3801 Limited, the State Rail Authority granted a licence to occupy the Large Erecting Shop at Eveleigh Railway Workshops.

They are also working on other stabling sites to support their operations and to relocate the remaining non-operational vehicles from the Large Erecting Shop.

Financial difficulties led to the suspension of the Cockatoo Run from November 1998 until March 1999, after which date the train ran between Port Kembla and Robertson only.

After being fitted with refurbished traction motors at Chullora Railway Workshops in October 2011, it returned to Eveleigh to be restored back to operational condition in March 2012.42101 is presently out of service.

[21] The 73 class are a diesel-hydraulic shunting locomotive built by Walkers Limited, Maryborough for the New South Wales Government Railways between 1970 and 1973.

7344 was retroceded to Transport Heritage NSW and in 2019 was offered for placement with other groups through expressions of interest and was subsequently placed into the hands of the Rail Motor Society at Paterson, New South Wales.

X54 was the last of the Series 3 X classes and went through a number of different owners including V/Line, Freight Australia, QR National and Aurizon where it was then placed into storage in Rothbury, NSW.
