Im sceptical but i also have high hopes, the route from london to reading is around 30mins on HST with fast trains but on stoppers it can be up to 1 hour. Lots of stopping pattens and journeys from Semi fasts and fast Readings, to peak time extras such as Maidenhead, Slough and Henley-On-Thames services.
166 looks great and so does the HST, bit annoyed that it only comes in GWR liveries but it still looks good.
Bit overpriced tho, as i dont have the CSX it would cost me £28, which is steep.
