Four GNRI steam locomotives are preserved.
The Railway Preservation Society of Ireland at Whitehead owns two of its 4-4-0s (one each of classes S and Q) and has custodianship of a third 4-4-0, (V class) which is on loan from the Ulster Folk and Transport Museum at Cultra.
The RPSI periodically operates one or more of them on special excursion trains on Northern Ireland Railways and Iarnród Éireann (successor to CIÉ) routes.
A 2-4-2T (JT class) locomotive is preserved at the Ulster Folk and Transport Museum at Cultra.

Some of its coaching stock has also been preserved.
1938 built dining car No.88 still sees use as part of the Railway Preservation Society of Ireland's Dublin based "heritage set" of coaches.
Also operating in this set is a 1954 built brake coach No.9, although it currently carries the number 1949.
The Downpatrick & County Down Railway also has an example of a third-class GNR six-wheeled carriage, in an unrestored condition.
