> it is not allowed to slam the brakes on if there is a train right behind you
So if we have three trains in close succession and the first derails or loses power, the second is not allowed stop because there's a train behind it?
> Trains are usually 10's of minutes apart, or at least 1 minute apart even in urban subway systems.
At least on the London underground it isn't unheard of for the next train to be arriving in 1 minute. Most delays are caused by passengers, not infrastructure.
