The interesting thing to consider is how the MHE branch can be made more
useful in the long term. One idea I put on my website is to have it as a
branch of Crossrail Line 2, and extend it to Watford Junction via MH

Just a couple of teeny problems with extending the MHE branch further
than Copthall at the moment: a business park (admittedly now closed),
a housing estate, the A41 and last but not least the M1 have been built
on the trackbed. I suspect moving that lot out the way might break
the budget somewhat.

Of course some of that section would have to be underground, and
therefore more expensive. However, undergrounding has its own advantage:
the line can be on a straighter faster alignment.
