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
Otira Tunnel tunnel in the world and the longest in the British Empire. The Midland Railway Company investigated options to a long tunnel; but a line over the pass with gradients of 1 in 50 on both sides was not practical. Other options for a line over the pass were a cable-hauled system or a line of 1 in 15 gradient using either the Fell system or a rack railway using the Abt system (or even a S-shaped tunnel under Mount Rolleston). However the government did not favour the Fell system as used on the Rimutaka Incline which was expensive to operate.
