As more modernised the GWR route gets with the new electrification of the route, the GWR route I think we need to see an update with the add of the Class 800/802 which is replacing whatever is left of the slow demise of the great HST and also the add of the Class 387 and a possible route extension, overall I think DTG is absolutely incredible and TSW is just amazing in every way and gives any Tain enthusiast the opportunity to get into the drivers cap and be the driver just hope to see this modernised update someday soon.
