The Geyserland Express was a long distance passenger train operated by the Tranz Scenic division of Tranz Rail (previously the New Zealand Rail Limited division InterCity Rail) between Auckland and Rotorua in New Zealand's North Island. It utilised the Silver Fern railcars and operated from 9 December 1991 until 7 October 2001.
The Rotorua Branch line had a long history of express trains between Auckland and Rotorua since the branch line opened in 1894. Until 1959, the Rotorua Express was steam-hauled and was one of New Zealand's premier trains in its heyday. It was initially only run thrice weekly in the peak Christmas and Easter period, but by 1902, it ran daily year-round, and in December 1903, dining cars were introduced. This was a rare feature for trains operated by the New Zealand Railways Department, but shortages during World War I led to their withdrawal. In the post-war period, the service was briefly cancelled in 1919, but by 1925, it was experiencing a resurgence as more powerful motive power became available in the form of AB class locomotives, and in 1930, it was upgraded to become the Rotorua Limited, completing its journey in six hours. It reverted to the name Rotorua Express in 1937, and during World War II, services had to be cut to thrice weekly due to coal shortages, and then to twice weekly after the war. Patronage plummeted as travellers opted for other modes of transport, but the Rotorua Express survived to be the last provincial steam-hauled express, operating for the final time on 6 February 1959. It was replaced by an 88 seater railcar service. The introduction of railcars on this route provided a significant improvement in service, operating six days a week on a five-hour timetable. However, the railcars soon showed signs of aging, and mechanical problems began to plague them towards the end of their service. The government of the day considered a replacement train too expensive and believed New Zealand Railways Road Services buses could provide an adequate service instead. The railcar service last operated on 11 November 1968. The only passenger trains to operate on the Rotorua Branch line for the next 23 years were chartered excursions.
