* Bring canals back into use

Which canals are not in use?

Actually, there's few in London, the longest of which by far seems to be
the Croydon Canal (closed 1836), but it hardly seems like a priority to
get it restored, especially as it would mean closing some railways which
have re-used parts of the alignment!

That'd be the Brighton mainline which uses the Croydon Canal alignment
between New Cross and Croydon - not sure if rail passengers would really
welcome transferring to canal boats to cover this stretch!

The London Canals website is the 'go to' reference site:
