the brighton,seaford,newhaven,eastbourne route i'm suggesting you add a couple of routes brighton,seaford,newhaven,eastbourne, hastings,bexhill,ore, london it gets boring with just from brighton seaford to newhaven - lewes - and eastbourne new routes should really be added onto the southcoast line
Post it in suggestions with more info. You only listed stations of one line and another line with no info
I would like to see southeast coastway merged with london - brighton and the wivelsfield - lewes line added, this would make a fantastic network route
