Will a freight train moving 55 mph take over 1 mile to stop?
It takes the average freight train traveling at 55 mph more than a mile to stop. That's the length of 18 football fields. So if you think a train can see you and stop in time, think again.

Trains can't stop quickly or swerve. The average freight train is about 1 to 1¼ miles in length (90 to 120 rail cars). When it's moving at 55 miles an hour, it can take a mile or more to stop after the locomotive engineer fully applies the emergency brake.
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.
Why can't trains stop quickly? Because there's not much friction available in the wheel-rail interface. Normally this is a good thing, the low rolling resistance of trains is why they're so efficient at moving heavy loads.
In general, freight trains typically operate at speeds ranging from 40 to 80 mph (64 to 128 km/h). However, some high-speed freight trains can reach speeds of up to 120 mph (193 km/h) on dedicated tracks.
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.
Did you know that the average freight train consisting of 100 cars and weighing anywhere from 12 million to 20 million pounds takes over a mile to stop in emergency braking? That's right! That's the length of at least 18 football fields travelled before coming to a complete 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.
Looking at traffic fatalities per mile traveled in the U.S., analyst Todd Litman found that riding commuter or intercity rail is about 20 times safer than driving; riding metro or light rail is about 30 times safer; and riding the bus is about 60 times safer.
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.
So, about 50% of freight trains are between 5,400 feet and 14,000 feet long. Despite a median length of about 1 mile, 50% of trains are over 1 mile long today. Average train lengths have steadily increased over recent years due to several factors. Market demand is a major driving force in train length.
10000+ kilometers, if the train consists of a standard US freight locomotive pulling one car. Can cover more than 1500 km a day, and can keep going for more than a week.
