Diamond Geezer has picked up the following from an online London Underground question time:
The trains won't go round in circles, they'll start and finish. One end of the line will be Hammersmith. Trains will shadow the Hammersmith & City line between here and Paddington, doubling the frequency of the service. Then they'll pull into Edgware Road (platform 1) before heading on a big loop all the way round the existing Circle line to Edgware Road (platform 2). And here they'll stop. And then they'll go all the way back round the loop again, via Edgware Road (platform 4) to Hammersmith. That's going to be fun explaining to tourists, isn't it?
There's more good stuff too, so read on.
