> Terminating a train and turning it around takes a lot of space, space that is usually unavailable in a city center.
This doesn't happen in London in my experience. Trains don't turn around, instead every train is double-ended. The driver gets out of the cab at the terminus, walks to the other end of the train and gets in the other cab. They can do it faster than the passengers disembark.
