Joint running with the
Night Limited for the Taumarunui-Auckland leg was the pattern for the 1930s, with the service provided thrice weekly on Mondays, Wednesdays, and Fridays.
AB class steam locomotives were typical motive power at this stage, and a train from
Hāwera connected with the
Express in
Stratford. At holiday times, the
New Plymouth Night Express was run separately from the
Night Limited due to large volumes of passengers, and as this service ran directly between New Plymouth and Auckland, it did not pass through Taumarunui, which is seven miles to the south of the junction in Okahukura; accordingly, a connecting train ran between Taumarunui and Okahukura. In 1940, the independent service began operating thrice weekly year-round. It departed Auckland at 7:50pm on Sundays, Tuesdays, and Thursdays, made refreshment stops in
Frankton and Taumarunui as NZR did not operate
dining cars at this point in history, and arrived in New Plymouth at 7:19 am the next morning. The opposite working left New Plymouth at 7:08pm on Mondays, Wednesdays, and Fridays, made the same refreshment stops, and arrived in Auckland at 6:30 am the next morning. Operating through to Taumarunui removed the need for a connecting train between Taumarunui and Okahukura, but it did mean the front of the train at the start of the journey became the back for the second leg and the seats were reversed. Sleeping car facilities were removed in 1944 due to restrictions caused by
World War II, and by 1950, the train ran only twice weekly due to coal shortages. At this stage,
J class locomotives had become the primary motive power and the train typically comprised two first class carriages, three second class carriages, and a guard's van. == Replacement by railcars ==
