Hello, here is my second Suggestion. This time i wanna suggest the Sheffield Supertram. The Network is having 4 Lines: Yellow Line Middlewood - Hillsborough - Cathedral - Arena - Meadowhall Interchange, Blue line Malin Bridge - Hilllsborough - Cathedral - Sheffield Station - Gleadless Townend - Halfway, Violet line Herdings Park - Gleadless Townend - Sheffield Station - Cathedral ( During Rush hour further to Arena - Medowhall Interchange) and Tram-Train Cathedral - Rotherham Parkgate. As Rolling Stock would come the Siemens-Duewag Supertram and the Vossloh Citylink class 399 I wanna have it in TSW 2, because i think its a quite unique network in the UK.
