Rimutaka Incline Rimutaka Incline The Rimutaka Incline was a , gauge railway line on an average grade of 1-in-15 using the Fell system between Summit and Cross Creek stations on the original Wairarapa Line in the Wairarapa district of New Zealand. The term "Rimutaka Incline" is sometimes used incorrectly to refer to other parts or all of the closed and deviated section of the Wairarapa Line between Upper Hutt and Speedy’s Crossing, near Featherston. The incline formation is now part of the Remutaka Rail Trail. The construction of a railway from Wellington to Masterton was authorised in the Railways Act passed on
Kaitoke Upper Valley Gliding Club for the purposes of gliding the area's thermals. The Pakuratahi River flows through the eastern Kaitoke Basin from its source in the Remutaka Ranges. The old route of the Wairarapa Line railway, which closed with the opening of the Rimutaka Tunnel in November 1955, ran from Upper Hutt via Maymorn to Kaitoke and around Goat Rock up the Pakuratahi to the Summit, and from there, because of excessive steepness, the Fell mountain railway system was used to aid trains on the Rimutaka Incline between Summit and Cross Creek. This railway is now the Remutaka Rail Trail.
