Yep, I'd rather it was named something else - although maybe not worth the rebranding costs to do so now.

However, in the best British tradition of nicknaming things I hope a common name evolves (the Suburban Line, the Outer Line etc).

Mind you, I'm still referring to it as the ELL (for our bit) and the North London Line for the other bit from Dalston. Friends of mine living outside of FH refer to it simply as the Orange Line...
