Could show proposed extensions to Heathrow T5 and DLR
extensions to Dagenham and Woolwich Arsenal.

I'm going to make special version(s) with future extensions
(Overground, East London Railway, DLR, Heathrow, etc).


Hillingdon spelt wrong.

After FarringTon it does not surprise me anymore ;-(
Thank you!


Perhaps a double-arrow symbol to pick out NR interchanges?

Will be added - eventually.
