> There can't actually be 2 crossrail trains per minute surely?
Official docs actually say "A train every two and a half minutes at peak time through central London ... trains accommodating up to 1,500 passengers"
http://www.crossrail.co.uk/route/
So it looks like no. It will actually take crossrail 5 minutes or more to exceed that daily capacity of Dugout loop.

You are right I didn’t remember correctly.
Still 5 minutes to exceed the daily capacity of this loop is a quite good result I think.

I would say that crossrail will be much higher capacity than that, since it aims to have 41 stations and London is a big city, so there is potential for the same train to carry one group from Station A to Station D, someone else from station C to Station G, another group to replace the first from station D to station K, etc. Large networks are just more useful than ones with 2 nodes.
Most subway lines will have peak scheduled throughputs of about 26-30 trains per hour, or a train every 2 minutes or so. The tracks can support more, but it's a good idea to have some schedule slack so you can send more trains through if things go wrong. Moscow's Metro does manage 45TPH, but that is achieved mostly by having a simplified track layout with no revenue branching.

Prague's metro C has a 90 second interval during rush hour.
I was always wondering about people running to get the next metro.
"Keeping the tube lines consistently running ~2 minutes apart is barely achieved..."
The Victoria line has been quite successfully running 36 trains per hour (100 second headway) at peak times for the past year. Peak = about 3 hours each in the morning and evening.
Like, I'd be incredibly impressed if they pull it off - I'm just dubious.
