Shunting Loco ORB No.1

Ohai Railway Board No.1

The Trust has been offered the opportunity to purchase 1947 built Ohai Railway Board No.1. ORB No. 1 is the forerunner to the NZR Ds class of locomotive which were first put into service as heavy shunters during 1949.

The Trust is currently undertaking a fundraising appeal to purchase and transport Ohai Railway Board No.1 from Pukemiro to Maymorn. This locomotive will provide the Trust with a level of redundancy when major work is required on Tr189 as well as forming a key role in future railway construction activities and shunting work at Maymorn. 

The locomotive is essentially complete although a number of components have been removed from the locomotive and overhauled. There is also an assortment of new old stock spare parts for the engine and gearbox that will be included in the purchase of the locomotive. As ORB No.1 is fitted with train brakes it will give the Trust greater control over work trains and allow us to run demonstration passenger trains similar to those formerly run by ORB.

Ab745 and Tr189 standing outside the shed on 14 May 2016

A fairly extensive shunt of the shed was done on Saturday 14 May 2016, in preparation for storing another 56-foot carriage inside. Sleeping car Aa1060 and Gumdigger A255 were moved onto the inspection pit area of road 1, clear of steam locomotive Ab745.

We took the opportunity to pose Ab745 and Tr189 outside the shed for a photo, part way through the shunt.

Another ballast wagon is in the paint shop. Rust and old flaking paint has been removed with a needle-gun, making short work of this laborious job.

Individual components from shunt locomotive ORB #1 are also being prepped and painted, including areas of the frame, headstocks and sand boxes.

We have also added a lot of backfill into the floor area of the workshop extension to our shed, using a small rubber-tracked excavator to move around 20m3 of hard fill.

A few photos from recent weeks follow.

Gardner 8L3 diesel engine being test-started by Dave Shaw of Shaw Diesels on 3 April 2015.

A successful start, with a goodly amount of leaves and dust blown through! Oil pressure was brought up using an external pump and starting current to the starter motor from a battery set. The oil pressure held well and the engine churned back into life without any further problems.

Remedial work recommended include overhaul of the fuel pump and injectors. Other than that we have a good engine, and attention can turn to the radiator, compressor...

ex-Ohai Railway Board locomotive No.1 arrives at Maymorn

On Tuesday 21st October we took delivery of ex-Ohai Railway Board locomotive No.1 at our Maymorn railway heritage site.

The locomotive was built by Drewry/Vulcan in 1947 for the Ohai Railway Board and along with being used on coal trains was used on some of the first diesel locomotive hauled passenger trains in New Zealand.

This locomotive will provide the Trust with a level of redundancy when major work is required on their current locomotive Tr189 as well as forming a key role in future railway construction, passenger operations and shunting work as the railway extends from...

Drewry 2248 /1947 was built for the Ohai Railway Board as their No. 1 and was joined by sister engine No.2 in 1957 effectively dieselising the Ohai Railway Boards Line.

ORB No. 1 is the forerunner to the NZR Ds class of locomotive which were first put into service as heavy shunters during 1949.

In 1968 Ohai Railway Board replaced the two Drewry locomotives with two new locomotives built by Mitsubishi Heavy Industries. No 1 along with No.2 were dispatched to the State Mines railway between Stirling and Kaitangata in Otago.

In 1974, both locomotives once again moved this...
