I think we should add like the old E2 classes, RMS Britannic, Furness Railway Locos, etc. If you have anything new you are making, please post them here and either add a link to DLS, or your own site.
I have a suggestion for a new line. The U.S. Transcontinental Rail Line and Locomotive Works. It would be nice to run the C.P. and U.P. engines that met at Promontory Point, Utah along the route.
