The hatching is after the tramstop so surely it can't be to protect that?
I'll come back to the report/rumour (delete as appropriate) that the Council was waiting for the tram contractors to clear off the road before it put some cycle-specific markings down. There's clearly room (although bus stops may cause issues) and there was some mention in the Leith Walk plans of linking LW to the George Street infrastructure plans, so I hope that's true.
