Brilliant idea. So who gets to rebuild the circle line tunnels so the
catenary can fit? Not to mention that unless you're planning on dual voltage
trains or re-wiring the entire circle line then it will still have to be
DC in the central section. And then of course someone will have to stick
some pantographs on the battery locomotives.

Btw, what is the cost of entirely replacing the met lines DC system and
installing 25KV including catenary? Quite a bit more than relaying some new DC
rails I suspect.
