Traffic and parking demands at Maymorn have already been subject to scrutiny during the assessment of a Resource Consent application for railway and tourist activities at that site. Private motor vehicle demands have been mitigated by locating the operational base of the railway on the KiwiRail Wairarapa Line. Passengers and visitors will be able to travel to Maymorn by scheduled passenger services. Some personnel involved in current construction work at the Maymorn site already take advantage of the Tranz Metro train services.
An initial assessment of the Kaitoke station location options indicates that a new station site to the east of the original site will minimise effects of traffic on local residents. Improvements to the Incline Road may be required to better provide for two-directional traffic, and the proposed use of a short length of GWRC forest will require a similar upgrade. The new Kaitoke site has the potential for a sizable car parking area.
Traffic demands can also be minimised operationally, by starting rail journey at Maymorn (or Upper Hutt or Wellington); by providing coach transfers for passengers to reduce the number of private cars, and by reinstating the full length of railway past Kaitoke to Summit.
