I think that due to Great western express being set around 2016 we should see some more HST liveries such as 43002 in Blue and Grey, 43185 and a FGW livery for the HST and 166. The GWR Class 800 were put into service in October 2017 thus about a year into the future for GWE but it would be nice to see and drive around. And if not GWR maybe LNER and Hull trains on a ECML route.
danielg37, allow me to repeat what's been said for 100th time : No further work if any kind is being done on TSW2020.
