Passenger services Passenger services were originally provided by slow
mixed trains, with a September 1878 timetable allowing for three daily to Palmerston North. The opening of the line to New Plymouth in March 1885 led to the introduction of trains between Wanganui and Hawera, with initially two services daily. On 31 October 1885, the privately owned Castlecliff Branch opened, diverging from the Wanganui Branch near its Taupo Quay terminus. From this date until April 1932, passenger services ran multiple times daily between Taupo Quay and Castlecliff; they became increasingly uneconomic after the
local tramway opened a line to Castlecliff and it was this factor that caused their cancellation. In December 1886, the
New Plymouth Express began operating on the MNPL, bypassing Wanganui. A twice-daily connecting service known as
"The Ferry" ran between Aramoho and Wanganui to connect with the Expresses. In Aramoho, it exchanged some carriages with the express so that passengers from Wellington or New Plymouth did not have to change trains to reach Wanganui and vice versa. By the start of the 20th century, the slow mixed services between Wanganui and Hawera had become the subject of complaints that they did not suit the convenience of the locals for whom they were operated. Residents began agitating for a dedicated passenger train to run daily from Wanganui through Hawera to New Plymouth and return. It was not until 1926 that such a service was introduced, the
Taranaki Flyer. It took approximately 4.5 hours to complete its journey, a considerable improvement on mixed trains. On 31 October 1955, the Flyer ran for the last time and was replaced by a
railcar service operated by
88 seater and
Standard RM class railcars. The railcars did not last long, as declining patronage resulted in their cancellation from 7 February 1959. From this point, regular passenger services ceased to operate on the Wanganui Branch. The
SteamRail Wanganui heritage organisation is based at the Wanganui terminus and it operates charter excursions from this depot as well as providing facilities for visiting excursions to replenish fuel supplies.
Freight services Freight traffic has always played a prominent role on the line, particularly when Wanganui had an active port. In 1878, the fact that one more train ran daily between Wanganui and Palmerston North than between Foxton and Palmerston North led Foxton business interests to fear that the more regular service would boost Wanganui's trade at the expense of Foxton. == Motive power ==
