How long does it take a 150-car train going 50 mph to stop?
A 150-car freight train at 50 mph needs 8,000 feet (1 and 1/2 miles) to stop; an 8-car passenger train at 79 mph needs about 6,000 feet (1 and 1/8 miles) to stop.

An average freight train traveling at 55 mph may take a mile (5,280 feet) or more to stop, the length of 18 football fields! Trains can stop, but they can't stop quickly.
Trains have the right-of-way because they cannot quickly stop for a motorist at crossings or for trespassers on the tracks. The average freight train, traveling at 55 MPH, takes anywhere from 1 to 1½ miles to stop. Traveling at the same speed, the average automobile can stop in only 200 feet.
“There are times when mechanical and operational issues could also result in trains occupying a crossing for extended times,” the email continued, “and when trains stop for mandatory safety inspections or federally regulated crew changes.”
Fact #4: Trains Can Stop, But Not QuicklyThat's the length of 18 football fields. So if you think a train can see you and stop in time, think again. Trains cannot stop quickly enough to avoid a collision, which is why vehicles should never drive around lowered gates or try to “beat” a train.
It would depend upon the length of each train car, of which modern train cars vary in length from 35 feet long to 90 feet long so if we take an average length of 60 feet per car the average length of a 100 car train would be approximately 6,140 feet long with two modern 70 foot long locomotives.
What happens if you stand too close to a train? Air between person and the train moves with high velocity due to dragging effect and the air behind person is approximately still.
The middle of the train is by far the safest for persons. The National Transportation Safety Board does not release comprehensive data on where victims were sitting during fatal train accidents, though some details are available in individual investigative reports.
Modern trains can travel seamlessly from conventional track to high-speed track. They simply travel slower while on conventional track. Passenger service on the conventional freight lines that criss-cross the United States today is limited to 90 mph at best.
With high-speed rail, train travel is always faster than driving. In many cases, it's even faster than flying, once you factor in the whole air travel song-and-dance. And if you do need to catch a plane, trains make it easier to get to the airport.
The Glacier Express is the world's slowest train, taking more than eight hours to travel between Zermatt and St. Moritz in Switzerland at an average of 18mph. Along the way, it passes over nearly 300 bridges, travels through 91 tunnels and takes in endless stunning Alpine views.
A train of 150 cars—the FRA's unofficial definition of a long train—carrying iron ore would run about 3,500 feet long, but an intermodal train of the same number of cars might measure 33,000 feet, according to John Gray, the AAR's senior vice president of policy and economics.
The reason that trains honk their horns so much at night is because it's dark and the trains aren't so easy to see. Even though the lights are on, we sometimes can't see them coming, especially around the many blind curves near or ahead of the train station.
Automatic train stop or ATS is a system on a train that automatically stops a train if certain situations occur (unresponsive train operator, earthquake, disconnected rail, train running over a stop signal, etc.) to prevent accidents. In some scenarios it functions as a type of dead man's switch.
