The Advanced Steam Traction Group (AST Group) was established in 2012 following the closure of the 5AT Project.
The Group seeks to promote the ongoing development of steam traction with the aim of prolonging steam operation of both main-line and heritage line workings for the benefit of present and future generations.
Our principal project just now is the design and construction of a revolutionary new locomotive to be appropriately named “Revolution”. It is being built in miniature scale (10¼” gauge) as a low-cost demonstrator of new and developing ideas. See the Revolution page for more information.
