ok np

London Brighton, South London and Midland Main Line has been done - but unfortunately I can't add ECML sorry to say.

Hey can you merge London-Brighton, South London Lines, Midland Mainline and the ECML?

I would but unfortunately there is a 6m difference between Willesden Junction of NLL and WCML South (I only know because I had the fun of lowering Willesden Junction 6m in WCML South - not fun, i can tell you that!)

you should link this route up to the new WCML South route

Unfortunately not, at present there is no easy way for me to merge those two routes ( i have tried but unfortunately the best that i could do is have stratford 700m out which would need a lot of work unfortunately )

Is there the possibility of North London Line and Great Eastern Mainline?
