My current favourite implausible scheme involves somehow (magic?) putting
tunnels in in the City that let Metropolitan (and District?) trains which
currently terminate at Aldgate (or Tower Hill) carry on to the east,
perhaps Canary Wharf, Lewisham and points south.


One that comes up about every 18 months in these parts is sending the
Metropolitan line from Liverpool Street, through Aldgate East and
Shadwell to New Cross and beyond.

Then someone always pops up and points that two trains can't pass on
that curve without doing severe damage to each other's paintwork, and
the whole thing gets forgotten.
