Ida Bay Railway Hunslet

Sheffield Steam & Heritage Centre

The Ida Bay Hunslet is approaching the completion of its extensive rebuilding and repair, as seen in this view dated 6 March 2025.

It had been reassembled for display at the 2025 Steamfest.

Remaining work includes fettling to fit the injectors, a lubricator, the smoke box door and various other components.

This dinky locomotive was built for the Australian Commonwealth Carbide Company for their Ida Bay Railway, an interesting Tasmanian operation linking a limestone quarry near the Hasting Caves to a wharf on Deephole Bay. High-quality limestone was shipped from Ida Bay to Electrona, south of Hobart, where it was reduced to lime in a kiln before being roasted with coke in an electric furnace to produce high-grade calcium carbide for acetylene gas production. Located in Tasmania’s far south, the Ida Bay Railway’s 7km route is said to be the most southerly railway in Australia.

This locomotive was built to Hunslet’s standard ‘Darwin’ design. For some reason it sported steam tram features, in particular an overall roof and oil trays under the cylinders and motion. I’m not sure why these steam tram features were provided, as the Ida Bay Railway doesn’t feature any road running. The Hunslet engine replaced an earlier Krauss loco ‘Puppy’ (0-4-0WT b/n 2640 of 1892) at the Ida Bay Railway and continued in service until 1952, when replaced by Malcolm Moore petrol locomotives. It was stored serviceable at Ida Bay until 1971, when it was purchased by the Van Diemen Light Railway Society (VDLRS) for preservation at their Don River Railway. The Hunslet loco subsequently transferred to their growing heritage railway and workshops at Don, where it was overhauled in 1992 and prepared for further service.

In the meantime, the Ida Bay Railway’s limestone cartage ceased in 1975, but the line was purchased for heritage purposes by the State Government in 1977. An operating model was implemented whereby the Ida Bay Railway and remaining rail assets were leased to a suitable operator for tourist services. The section from the quarry to Lune River village fell into disuse and was later ripped up, whilst the section from Lune River to Deephole Bay was retained for tourist services.

The Hunslet loco returned to Ida Bay in the early 1990’s under lease from the VDLRS to the railway’s operator at that time. It received lined red livery, was given the identity No.6 ‘Old Thomas’ and began operations in 1993, albeit with the overall canopy removed – considerably changing the loco’s appearance. I understand the loco didn’t get much use at Ida Bay (with most services handled by internal combustion machines) and eventually the Hunslet returned to the VDLRS, Don. As per the photo below, my visit to Don on 8 May 2003 found the Hunslet under overhaul with the boiler removed.

The Hunslet loco has since been relocated to the Sheffield Steam & Heritage Centre, where boiler and other repairs are underway in preparation for steaming on the Redwater Creek Railway. Recent posts (October 2020) on the Sheffield Steam & Heritage Centre social media page show that boiler repairs are well advanced, with a new firebox having been fitted and retubing completed. I understand the mechanical work is also complete and only reassembly is outstanding, so hopefully this interesting locomotive will soon be riding the rails again.

Alas there were no trains running at Lune River at the time of my visit there in May 2003, but I recall being intrigued by the various ancient railway artefacts lying around the rail yard – a locomotive cylinder disappearing into the grass, driving wheels stored by the running shed, and two locomotive frames slowly rusting away in the sidings. Highlights of our trip to this far southern tip of Tasmania included a guided tour of the nearby Hastings Caves, and a magnificent bushwalk starting from Cockle Creek on the east coast – after walking for an hour or so, we emerged on the west coast!

This page would be improved with photos showing the Ida Bay Hunslet in operation and / or in original ‘tramway’ configuration. Photographic contributions would be much appreciated.

Light Railways magazine of February 2001 provides a good account of the Ida Bay Railway and is available online.

Update – August 2026:

Returned to steam after 25 years! he Hunslet operated under its own steam for the first time in a quarter century on New Years Day. Here’s a photo of the current RWC fleet from January

This January 2026 view shows the Sheffield Steam & Heritage Centre loco fleet lined up outside the running shed.

At far left, the smoke rising from the Ida Bay Hunslet’s chimney tells of its return to steam!

Also present is the hybrid Krauss loco and a beautifully restored Malcolm Moore 4 wheel internal combustion loco (far right).

My thanks to James Shugg for contributing this photo.

The Sheffield Steam website includes this wonderful table of Hunslet loco types; the Ida Bay machine is of ‘Darwin’ type.

(It seems this page is an excerpt from a marketing brochure from Hudson of Leeds, makers of light railway equipment.)

The repaired boiler has been fitted and the loco appears to have a newly fabricated smokebox, with the original chimney mounted.

Hopefully its reassembly will culminate in a return to its original and unusual tramway configuration.

A second view of the Ida Bay Hunslet at the Sheffield Steam & Heritage Centre ‘Steam Fest’ event on 12 March 2023.

The motion is in progress of being refitted, with a valve rod suspended at a jaunty angle – presumably so the loco could be shunted out of the shed.

I understood the loco has a new firebox; this view suggests a new inner firebox within an older outer firebox. The boiler barrel may also be new.

An interesting feature is the oil tray extending under the cylinders and motion, part of the steam tram configuration.
