Getting rid of the greenway trail will be unpopular in itself, of course.
Maybe Hornsey depot could be converted into a park? 
Trouble is, the trail is a vital part of the Capital Ring footpath
network. If you convert it back to a railway, you'll have to find
other trails connecting Highgate to Finsbury Park to replace it. (Or
find an alternative route for the Capital Ring to get from Finchley to
Stoke Newington avoiding Highgate and Finsbury Park altogether.)
