Overview of the Henschel GMAM

Discover the impressive GMAM steam locomotive, a 4-8-2 powerhouse built by renowned manufacturers like Beyer & Peacock, Henschel, and NBL between 1953 and 1958. This Garratt series locomotive, with its distinctive 1067 mm gauge, is a testament to robust engineering.

Spanning 28.6 meters and weighing a substantial 245.7 tonnes, the GMAM was designed for efficiency on mainline routes, capable of hauling trains up to 41.98 meters. Its imposing height of 3.96 meters and an axle load of 15.95 tonnes highlight its formidable capabilities.

Today, the GMAM continues to capture imaginations, notably with the Mainline Steam Heritage Trust in New Zealand, where the MS GMAM class is lovingly preserved. This locomotive stands as a proud symbol of historical railway engineering prowess.
