Train Sim World 2

Hi
I was wondering as we have east coast railway from Brighton to Eastbourne. Would we be able to have a southen route from London to Brighton calling all stops with a choice of having a express with the class 377 and then maybe have updates of having route add on like London to bognor regis and then we can couple the 4 formation to 8 or 12 at Horsham or drive a 12 car and carry on to London and back. I think it would be fantastic because we all could have a choice where we want to go and it could be a best seller for pc xbox one ps4
I am looking forward to your response
