key elements of the Maymorn development, including yard track, water vat, rail vehicle shed, station building, signal box and pedestrian crossing

The Maymorn operational base is important in a number of ways. It is the current focus of volunteer activity, which the Trust is entirely reliant upon for its future. Tranz Metro Wairarapa Line passenger services service Maymorn, which provides connection to and from Wellington, the Hutt Valley and the Wairarapa — and strategically, a future life-line for tourist visitation to the railway.

The facilities under construction at Maymorn will protect the Trust’s current rail vehicle fleet, and facilitate their future restoration, operation and maintenance. Plans have also been prepared and resource consent approved for a large station building incorporating a visitor centre, historic and interpretative displays, and a cafe. These facilities will play a central role in the Trust’s future operations, being the departure point for a journey back in time over the historic Rimutaka Incline.

Heritage station precinct

The proposed Maymorn station will be the first heritage station encountered on a passenger's journey northbound from Upper Hutt, and has been designed to perform as an interchange and junction between the mainline and heritage railways.


Safety is a primary requirement of all operating railways, and the proposed layout of the Maymorn station yard has been drafted with this in mind. There is clear demarkation of public and operational areas, and it is possible for an intending passenger to board their train without having to cross a single railway track. Proposed public access to the station is via Parkes Line Road, which includes carparking and a tour-bus turnaround area.


It is initially proposed to provide facilities for trains up to six carriages long, which will have sufficient capacity for 200 passengers. Station buildings, platforms, crossing loops and storage sheds will be designed to suit this traffic. Provision will be made for future expansion to serve trains up to twelve carriages in length, which would have the capacity for 400 passengers. Provision for future capacity is critically important - in order to avoid the time-consuming and expensive task of dismantling and relocating initial structures and infrastructure.


A crossing loop and access to the storage shed are initially proposed, located to accomodate future expansion. A ladder road diverts from the RIR mainline immediately south of the platform, leading to the storage shed and storage sidings. The crossing loop is able to be used to run around rolling stock or train stopped at the platform, or to shunt the ladder road. Additional storage roads may be added at a later date.

Rail vehicle shed

Storage sufficient to house locomotives and carriage stock will be essential, to provide protection from the elements, security and maintenance and restoration facilities. With careful planning much of the interior of these buildings could be open for public viewing, (excepting machine shop).

Maymorn station building

An authentic heritage station building is planned for Maymorn. A full set of drawings have been prepared by conservation architects, based off a George Troup design dating from 1907.


A 70' (21.3m) turntable is proposed, capable of turning the largest of former NZR steam and diesel-electric locomotives. Initially it is planned to operate the railway with locomotives that can operate safely in either forward or reverse directions, to postpone the expense and trouble of installing turntables at both Summit and Maymorn. The turntable at Maymorn could well be the first to be installed, so that locomotives hauling trains from Wellington to Maymorn can be turned in readiness for return journey.

Loop track build starts

During July and August we have started building the loop track at Maymorn, which extends eastwards from the double slip. The formation is already prepared for the loop, sloping to the cess drain to the north side. The loop passes through a short curve past the slip, then its straight-running through to and past the pedestrian crossing.

The loop will initially be used as a storage siding and will be useful to shunt wagons and carriages that are 'uphill' of our shunt loco.

Native shrubs and trees

Bart and Graeme have done a wonderful job tending to the native shrubs and trees planted at our Maymorn site. A host of native shrubs and trees have been planted alongside our future mainline formation to the Kaitoke side of the pedestrian crossing. The plants have taken despite the arduous ground conditions and occasional accidental dose of weedspray - a vast improvement over the gorse and blackberry the previously occupied the area.

Track extended past gate

On 7 February 2015 we extended our mainline track past the gate towards Maymorn station. Just a short distance, but great to be heading "up the hill" with the track again.

A few tasks had to be completed in the preceding weeks, including excavating and installing a field-drain to take surface water away from the pedestrian crossing area, rails cut and drilled, sleepers adzed and pre-bored. Further extension of approximately 100m is pending removal of hard fill from the future loop formation.

Earthworks for workshop and track extension

A 12-tonne excavator and dump truck were hard at work at Maymorn on Monday 12 January, excavating and moving spoil from the north end of our station to backfill the foundations of our workshop. The formation for our forthcoming track extension was widened and tidied up as well - with additional space cleared alongside the loop formation and a cross-drain put in.

Around 50 cubic metres of good quality base course was moved into the workshop formation, as the photos below show. Over the next week or two this will be spread and compacted in preparation for the concrete floor.

Wb 299 rebuild under way

The rebuild of Baldwin steam locomotive Wb 299 is now well under way. The first major components - cab and bunker side were fabricated in time for display at RailEx. A cab seat and raised section of cab floor were added to make a more interesting exhibit, which proved quite popular with visitors.

Workshop foundation wall completed

On Saturday 29th November we passed another milestone with our workshop shed construction - completing the foundation wall. A few weeks of preparing formwork had paid off with a single building inspection and pour, a central column pod included in the job. We're grateful for funding recently received from Rimutaka Trust, which has been another major boost for our workshop project.

Workshop build progress

A huge effort put into the workshop over the weekend of 4-5 October, all four barge boards lifted up, flashings fitted and soffit installed at the Upper Hutt end. We're very close to completing the roof - which will be a most welcomed milestone in this project.

The weather was patchy at best, but thankfully not as bad as was forecast, and we got a huge amount of work done. Thanks to all who helped out!

We're now able to clad the Upper Hutt end wall - the ColorSteel sheets on site ready to install.

Ballasting operations 23 August 2014

On Saturday 23 August 2014 we were fortunate to have Peter O'Flaherty, local Upper Hutt Contractor, load up ballast wagons for us at Maymorn. 

Four of our fleet of Yc ballast wagons were pressed into service, including recently overhauled Yc817, hauled by our Hillside Tr189. Ballast was discharged and spread at a few different spots, including the shed yard and a stretch of our mainline.

Funding boost for workshop project

We are delighted with the recent round of funding support, which adds to that previously received from Rimutaka Trust, Pelorus Trust, Rotary Club of Upper Hutt, Upper Hutt Summer Carnival, The Lion Foundation and Trust members.

First public run of Cyclops at Maymorn

Another milestone for our railway on Sunday 11 May - the first public operation with a locomotive-hauled train. Our Hillside Tr189 did the honours, hauling D2411, one of the trailer cars that make up the 'Cyclops' electric multiple unit set.

With the locomotive-hauled train we can now cater for trains rides for around 40 people at a time. People can enjoy a short ride in our station yard, with the added nostalgia of the English Electric units that were withdrawn from service on the Wellington network back in 2012.
