The Rail Motor Society is incorporated under the NSW Associations Incorporation Act, 2009. Incorporation gives the Society its legal status under NSW legislation and permits it to own real property and to enter into contracts. It is also a prerequisite for the Society to undertake its primary function as a railway operator, that is to be accredited by the Office of the National Rail Safety Regulator under the Rail Safety National Law and to enter into Access Agreements with rail infrastructure owners such as Sydney Trains, the Australian Rail Track Corporation and others.
