Now available for MSTS over at trainsim! Jon Davis has made really fine models of these engines, which do require Xtracks for the train sim, as they are 3' gauge models.
Meanwhile, my model of the SVRy is slowly taking shape. I've got track laid to just beyond Salibury now. A lot of custom textures are going into this, along with an awful lot of research! I'm behind, and now figure on somewhere around March 1st for a release of the route as far as Sumpter.
