This historic area was registered under the Historic Places Act 1993. The following text is from the original Historic Area Assessment Under Section 23 Criteria report considered by the NZHPT Board at the time of registration.
DESCRIPTION:
The 16 kilometres of railway formation between State Highway 2 at Kaitoke and the former rail settlement at Cross Creek is now a popular walkway. It includes the historically significant Remutaka Incline. Annually, some 30,000 walkers, runners and mountain bikers use this rail trail.
The section of rail formation between the Summit and Cross Creek is known as the Remutaka Incline. It is a 4.8 kilometre stretch of steep mountain railway. Trains travelled the Incline to and from the Wairarapa from 16 October 1878 to 29 October 1955 when rail traffic was re-routed through the new Remutaka tunnel. The railway was twice as steep as the steepest mainline railway in New Zealand. A special 'Fell' system was employed to assist the locomotives grip the rails.
The Incline's formation, which includes embankments, tunnels, culverts and associated structures and occupation sites (Summit yard, Cross Creek and campsites), are archaeological sites as defined in section 2 of the Historic Places Act 1993. Trust authorisation is required for any works that might modify or damage these sites. Artefacts and remnants of railway structures continue to be found in the vicinity of the Incline, and many remain uncovered.
A lengthy part of the route is vested in the Wellington Regional Council which has allowed sections to be used as a logging route - with serious implications for maintenance of the formation. The Department of Conservation manages the area from Cross Creek to the Summit Tunnel under a conservation plan.
