This suggestion is the Winchester - Bath Spa line for tsw 2. The route is approximately 67 miles long. The stations along the line Are: Winchester, Shawford, Eastleigh, Southampton Airport Parkway, Swaythling, St Denys, Southampton Central, Salisbury, Bath Spa. The Locomotives that run this line are: Class 159 Class 158 GWR/SWR livery, Belmond British Pullman's Historical Bath tour, Class 66, Class 166/165, Network Rail Class 43 HST, Class 701, Class 444, Class 450. This would be a really good route and would add to the UK route variety.
