Well, I think that the braking system for a large train wouldn't be nearly as smooth as the LRT. I does tend to get jerked around a little on the commuter trains in Chicago, or even the EL when they come to a stop. The braking system on the LRT is surprisingly smooth (incredibly so in my opinion), and even it had us getting jerked around a bit when the driver was slamming on the brakes coming up to the car.
