Not even going there with the bus, but for the plane comparison, I shall have to be more specific seeing as I should have realised someone would use a tiny plane. Let's say something using a 737-800, a 787-900 or even a A380.
I wouldn't, but a train[1] is more similar to a bus than to a plane, so I don't agree with your rejection of the comparison.
The key differences are:
- Two pilots rather than one because a plane can't just whack the brakes on if the pilot goes unconscious
- Evacuation has to be completed in the event of a crash within minutes otherwise everybody dies (this is where the small plane differs as it's more like a car in terms of getting out)
Neither of those are true of a train. If the driver, as the only member of staff, goes unconscious, the train automatically stops and everyone is safe remaining on board until evacuated. (It's no fun, but they are safe). And regarding evacuation, in almost no case on the railway does this need to be rushed - almost always it is *less* safe.
They simply are not comparable.
[1] OK, not a 12 car London commuter train, but a Class 153 has a similar capacity to a large coach or double decker bus, and in London the same number of doors, too.
