Mangaroa railway station Mangaroa railway station Mangaroa railway station was a single-platform rural railway station on the Wairarapa Line between Upper Hutt and Featherston in the Wellington region of New Zealand’s North Island, on the section that was replaced by the Rimutaka Tunnel deviation in 1955. It served the small rural settlement of Mangaroa, in the Mangaroa Valley, east of Upper Hutt. Mangaroa station was not originally built prior to the opening of Kaitoke station as part of the Mungaroa Contract. During the construction of the Rimutaka Tunnel, a siding was laid from the eastern end of the Mangaroa Valley and several chains
Rimutaka Tunnel at that time. It was not until the 1920s that significant campaigning for a replacement again prevailed on the government. In 1921-22 a feasibility study was conducted, including distances and estimated costs. Several routes were considered, including variations on previous ideas, but nothing more was done at the time; although a deviation of "about 5 miles 48 chain" (9 km) as the Wellington-Napier Line (Rimutaka Deviation) "running generally to the south-eastward of the existing line" was authorised by the Railways Authorisation Act, 1924. The new Labour government of 1936 announced its intention to proceed with the Mangaroa to Cross Creek
