Pretty basic: -Clapham Junction / Richmond to Stratford Why must I suggest this? Well, Not only do we receive a nice lengthy passenger suburban route served by the class 378s, it would provide a very very useful freight corridor IRL and In-game. It would connect 3 of the in-game mainlines, the BML, GWML and the SEHS altogether, with space for Both the WCML and the ECML and the GEML too. For example, it would finally allow Aggregate trains to travel from Newhaven Harbour to Acton Yard and further, or some heritage stock from Southall to London Victoria to begin the Brighton belle (I am not saying this will finally be possible with the Overground lines however this is just to back-up the point). What could also be added is the GOBLIN line from Gospel Oak to Barking, since we already have the c2c tracks laid as far as Grays, we could have Dagenham Dock / Barking to Acton Yard trains. So, do you think this should be added? A fairly reasonable line that could finally give your freight a useful purpose?
So basically in theory it would connect: -the SWML -BML -GWML -WCML -Chiltern ML -ECML -SEHS/HS1 -GEML -Chatham Mainline
