Why do freight trains stop randomly?

Sometimes, the trains can stop in the middle because of technical or mechanical problems with locomotives or picking or dropping off the freight cars at the industrial tracks. They can also stop in the middle because they are waiting for the section ahead of them to get clear of a train occupying it.

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.

One of the primary reasons railroads use distributed power is to increase the pulling power of the trains as the length and weight also increases. By placing additional locomotives in the middle or at the end, the overall pulling power of the multiple locomotives increases, moving the train efficiently and effectively.

The train whistle, or horn, is an important part of our safety practices. The horn alerts people that a train is approaching a railroad crossing. It can also be used to warn animals or trespassers in our right-of-way along a section of track.

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.

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. The heavier the object, the longer the stopping distance.

The train is faster, bigger, and more powerful – it can't stop fast enough to avoid you. People have died because they tried to outrun a train. Pedestrians have died because they were walking on the tracks and did not realize how fast the train was coming.

It is absolutely not legal to ride on any part of a freight train without the express permission of the railroad. You would be guilty of trespassing and of theft of service since you would be getting railroad transportation without paying for it.

Derailments rank as the most common type of accident involving major freight railroads, federal data shows. Equipment failures are increasingly responsible for derailments, and problems with equipment and train tracks accounted for nearly 60% of derailments nationwide last year.

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.

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. These trains are usually 1500 m to 1800 m long, and pulled by two or three locos of around 3,000 kW power.

Usually trains have multiple locomotives, and defects that stop the entire train are rare. Usually they will just isolate or shut down the bad locomotive and carry on to the next yard, where that locomotive will be swapped out and sent to the shop.

One long whistle (three to 10 seconds) means the train is approaching a station.

Train Horn Requirements Under the Train Horn Rule (49 CFR Part 222, issued on August 17, 2006), locomotive engineers must begin to sound train horns at least 15 seconds, and no more than 20 seconds, in advance of all public grade crossings.
