Engineering Group


During running days train rides are run behind powerful miniature locomotives (sometimes steam). Come along to get your taste of these amazing pieces of machinery and so much more. Above we see Mr. G. Chapman cleaning down his Simplex type locomotive after a hard day out on the track during Festival Week.

See the video below for a lap of the track pulled by a "Butch" type locomotive (W127), built and owned by Mr. D. Burrows.

The Engineering Group encompasses all forms of model engineering enthusiasts from first timers, to experienced model builders working in metals, wood and plastic. There is a wide range of models and tools built from the simplest steam engines to the most elaborate locomotives and machine tools. 

We don't just build steam models, there are IC engines, petrol and electric engines, high speed cars (tethered cars page), machine tools, measuring equipment, clocks and anything in between. At meetings (see below for times) we discuss modeling techniques and run training nights in workshop methods.  We try to have “field trips” at least 4 times a year to places of interest around Otago.

Working bee’s to improve our facilities are always on the cards too. All new members of the club, no matter their level of experience are welcome to attend. Members are more than happy to help new modellers with their projects with advice when needed.

Our outside multi gauge railway caters for 2 ½, 3 ½, 5 and 7.25 inch gauge locomotives with a maximum working weight of 500 kg’s. The steaming bays have water and compressed air on hand with secure storage for locomotives.

This group meets every month on the 3rd Monday of the Month at the OMES clubrooms at 7:30pm.

Like to join??

Phone the group leader (see below) or come to our running day on the Last Sunday of the Month, (weather permitting, check Facebook for updates) and make yourself known to the members there, and fill out an application form (information to go with application, different page).

Engineering Group Facilities

  • Outside Railway Track (2.5', 3.5', 5', 7.25' Gauge Raised Track, limited to locomotives of 500kg (unloading reasons)
  • Air operated points (some), signaling systems (4 locomotives or more on track, blind corners and points protected)
  • Steaming Bays, Steaming Shed and Electric Shed (Running Water, Compressed Air every track, coal and char, oils, kindling, locomotive storage)
  • Club Workshop, (lathes, drills, metal forming machine etc.)

"A lap of our track"- Engineering Group 

A lap of our outdoor track (raised, multi-gauge) behind a Simplex. This locomotive is driven by Andrew Douglas, whilst also videoing it. For more information on our outside track, look on our Engineering Group Page.

New signal system



New signal system designed and built by Mr. K. Da Rin for use on the outdoor multi-gauge railway when 4 or more trains are operating. These latest additions protect the blind corners on the track, round past the electric shed and carpark (pictures above) and the back corner from around the boat pond.

Other signals on the outdoor railway are located at St Kilda Station to indicate the position of the air operated points up to the steaming bays and also around by the tunnel to indicate the position of the air operated points through by the electric shed (see below, Ken setting up during a Festival Week exhibition).

The signals are run off 12V batteries (see pictures) and are run using micro-switches which trigger relays inside the signal. The connections are being upgraded to plugs (most three pin) so that they can be set up easier and the wiring order is correct resulting in correct indications.

Ken screwing wires into 'chocolate block' connector before Festival Week running. This signal protects the points through the tunnel, with an extra warning light in the tunnel. Relays and servos operate the semaphore arm.
