This would involve GWE and Bakerloo Line at Paddington in both routes have some sort of portal like how to load into scenarios in route, but the portal takes the person into the other route and but keeps same time and weather settings or perhaps adds the amount of time it would take to get there in real terms this could also be replicated onto RRO and RSN using a similar method at Hagen or at Brighton for ECW and London-Brighton (I don’t think there is any other route that joins like this yet) Just thought this would be quite a good method (like temporary or compromise) of joint route until or if they could be physically connected
Excellent idea and for Bakerloo Line linking to Great Western Mainline London Paddington to reading it should be a passageway linking the two.
