Sounds like a fanatastic idea.
Are they really thinking of doing it though?
DLR seems to be extending every which way but west.

A Charing Cross branch sounds good. But isnt it just as easy to go to
Tower Gateway and jump on a circle/district. If there already tunnels
there and some prework already commenced then maybe it possible. It
would certainly be used by many as its a useful route to st pauls too
for the tourists.

A farringdon branch seems somewhat redundant when crossrail comes along
(if it ever does) as you'll be able to connect into the DLR at WIQ and
IOD crossrail. But right now would be a useful addition as its not that
straightforward to get to Farringdon. (best route for me is DLR to Bank
then a bus or walk even. I also guess that would also involve expensive
tunnelling from Bank to Moorgate. Do DLR have that kinda money?

The only other problem I see is that the DLR especially the Bank branch
is heavily congested as it is. 3 car will help but i'm sure the
additional capacity will be quickly used up. So running to farringdon
or Charing cross will just add more and more people onto an
already congested system. Well have those tourist taking it to St Pauls
for instance.

But worthwhile ideas for extenstions. If only to allow addtional
connections into the tube network. (Bakerloo and Northern at Charring
Cross and Thameslink Hammersmith and City at Farringdon)
