I'm kind of with the OP on this, mainly because I'd like to see a route that covers Salisbury, I'm thinking something like Bath/Chippenham to Weymouth, or a variation of that theme. Not all Southwest Trains territory I know although they did cover the route.
Woking to Exeter St Davids would be good - give the 159, 50 and 33 a good stretch. Nice link between the Portsmouth Direct Line and the Riveria Lines.
I have got a PS4 so i don't have Southwest Trains on it especially now it has new livery. Please add a train or a route. I hope you can do this for PS4 owners.
