I don’t know if this one has already been mentioned, but who would like to see c2c included into the game? You have the scenery of Southend and the city too. There are also a few branch lines so it could be a cool inclusion?
Here to help, Noddy may i point you into the right direction : C2c Route Southend Central- London Fenchurch Street | Dovetail Games Forums
Not sure with two threads which to reply to. C2C is hardly a much loved company and the current stock isn’t that exciting. Despite the issues of modeling older periods a BR Electric in blue might be more interesting. The Class 302s for example spent decades on the line and the idea of slam door older electric might be popular.
