Summit railway station, Wellington Region Summit railway station, Wellington Region Summit railway station was at the summit of the Wairarapa Line over the Rimutaka Ranges in the Wellington region of New Zealand’s North Island and was where trains were marshalled for a descent down the Rimutaka Incline or for Fell locomotives to be extricated from a train that had ascended the Incline. The station was between Kaitoke and Cross Creek stations on the Wairarapa Line. The station was bypassed when the Rimutaka Tunnel was opened. Summit had no platform or other passenger facilities, did not consign goods or otherwise serve any settlement save for the
Rimutaka Tunnel tunnel. Detailed surveys were completed in 1938/1939, but the project was again postponed due to World War II. After World War II it became a matter of urgency to consider a replacement. The H class locomotives were showing their age, the Incline was in bad shape, and maintenance costs were increasing. Between September 1945 and July 1947 four options were considered. It was accepted that no contour line could be the solution and that a tunnel under the Rimutaka Ranges was the only satisfactory answer. The adopted route was the shortest route, a tunnel between Mangaroa and Lucena’s Creek gully.
