Train A is traveling at 70 MPH. Train B is on the same track as train A and traveling towards it. Train B is traveling at 60 MPH. The train track runs east and west. There is a 15 MPH wind coming directly from the north. The weight of the cargo on Train A and B are both 1,000,000 1bs. There is 45 people on Train A, and 100 people on Train B. Just as the two trains approach each other 65 percent of the people on Train A jump off and 90 percent of the people on Train B jump off. After the two trains collide, how many people will be left on board asuming 3y=x?

We need more info! Were there any time zone changes? Is Hell on EST? Are they traveling east and west? Saying they are east and west bound doesn't tell us which way they are traveling, just where they are going! Can two objects really leave the same point? Instead of saying 60 mph for 2 hours and 70 mph for 2 hours couldn't you just say one traveld 120 miles and the other 140?

There isn't exactly enough information to answer the question.
Just as mentioned if both trains passed a stop signal indication the train automatically goes into emergency. The question doesn't have info. on whether the tracks are signalled, dark territory, etc. But the answer to the question is, no one would be killed because both trains would go into emergency after passing the stop signal indication or the brakes would apply after the trains passed a signal with a slower speed aspect such as a 'approach signal" telling the enigineer the next signal is a stop signal.

I'm with HOGHEAD on this one..
But alas, I would say the ATS (Automatic Train Stop) would kick in after passing the first restricting signal at 65 or 70 and no one would get killed because both would come to a full service application stop.
Add'l Info: That, Mr. Railfan is why ATS is active on any restricting signal lower than "clear" from approach medium (if applicable) down. I don't know of any blocks that go from clear to stop - there is always a restricting signal.

Sounds like a lot of body bags... I doubt even the ones that jumped would survive.... and fellows all tracks are not equipped for train control....

no, I doubt both trains at that speed would be able to stop within the block, even with ats. So, I would have to say that Amtrak will be giving a lot of posthumous refunds thiis time.

None. The remainder are ground up like hamburger.
