The Experience
This is not a train tour. This is an insider’s 4WD expedition into Queensland’s railway history.
Discover a part of Southern Queensland few have ever seen. The 4WD Heritage & Engineering Marvel Expedition is a premium, small-group guided adventure through the spectacular and remote Silverwood Range railway corridor between Warwick and Stanthorpe. Operated by the Southern Downs Steam Railway Association Inc. in joint venture with the private landholder, this exclusive experience provides controlled access to nationally significant 1880 built historical railway engineering works, dramatic escarpments, historic stone and timber bridges and rare infrastructure, normally inaccessible to the public. It allows for same-day return travel from Gold Coast, Brisbane, Toowoomba or Northern NSW.
Sights include: Connolly Dam, impressive Mineral Creek Bridge stone pylons, the Gorge tank and Gorge Dam, Overend Tunnel and mountain top vent, Southern Tunnel Portal and the substantial Cherry Gully Timber Bridge.
