The New South Wales Tulloch double deck carriage stock was a class of electric multiple unit (EMU) carriages operated by the New South Wales Government Railways and its successors between 1964 and 2004.

In February 1964, the first of 120 double deck trailers was delivered by Tulloch Limited to the New South Wales Government Railways.

In order to create a consistency with the stainless steel carriages they operated with, T4852 and T4867 were repainted in an experimental silver livery.

After a three-year lapse, T4872 was repainted flake grey and this was gradually rolled out to those carriages in S sets with the last completed in June 1993.

[4][5] Over 15 carriages remain in existence, including T4916, the only surviving manual door double deck trailer.
