I'm not going to get in the middle of this disagreement, but just to clear up the facts:
Wheel
slip is when the wheels are moving faster than the rails, under power.
Wheel
slide is when the wheels are moving slower than the rails, under braking.

Again, I'm staying out of the drama, but from my understanding of train handling an engineer wouldn't stop a train moving 30mph with one application. You can't "ease off" train brakes if you brake too hard, and I can't imagine the ride would be too pleasant either. More likely an engineer would make a minimum application to slow the train, then a second application, on top of the original, to stop. For example, 5lbs upon hitting the platform and another 10lbs (15lbs in total) to bring the train to a full stop. I am not going to speculate on when the emergency brake application was made since I am not in the know.

Well said, Mike. I second both of these sentiments. Every winter I reflect upon how resilient the railroad is compared to other modes of transportation. I'd put them on par with the far-more-flexible road system in terms of availability, and unlike airlines they don't completely shut down when something major fails. They just plug away at keeping people moving as quickly and safely as possible. Sure, the inflexibility of the system makes railroads susceptible to delays, but those buggers are hard to kill! Keep it up, folks.
