I was wondering if we can transfer from route to route in the future. For example, if you have Great Western Express, you can go through a portal at Paddington to the Bakerloo Line platform at Paddington. Even if we can walk through, it would be nice to roleplay by saying that you take the Tube to Paddington, and then drive a service to anywhere on the mainlines. Could we please have this? One problem with this is that this is the only place where I can imagine it working in TSW2 (TSW- LIRR-NEC at Penn)
