Not sure if the class 170/1 runs to ashford out of Brighton anymore or any service goes there anymore, actually i was looking on the NR app the other day and i saw everything but Ashford, dont even think i saw London Bridge.. anyways would be nice for some extentions and more variety, ore, hastings, bognor, portsmouth, instead just one platformed Seaford.
Another route for what? Plus it's almost 100% certain the next route is US freight. Anthony has Matt's words on discord somewhere here.
