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.

Membership of the group is open to all. Please contact us through the contact page of this website.
