Extension of the New South Wales North Coast railway line from Kyogle to Brisbane commenced in 1926 and generated additional traffic on the tramway carrying construction materials. This led to considerable delays with services unable to run to the timetable. Rathdowney and nearby towns were served by the interstate line from 1930. Traffic volume on the line experienced significant decreases starting from this time. Following the "encroachment" of the standard gauge line and increasing competition from road transport, the Shire approached the Government of Queensland to take over the Tramway but the Minister for Railways declined.
