How long does it take a freight train to come to a stop?

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.

Physics, the trains are very heavy, and therefore have a huge amount of rolling mass that produces momentum, there is also very little friction between steel wheels on steel rails, and it takes up to a mile of distance for a planned stop when traveling at speeds in excess of 50 MPH on a fully loaded freight train.

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.

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.

Freight, Engine, Locomotive, Car. How much does a train Weigh? A train can weigh anywhere from 4,000 tons (8,818,490 lbs) to 20,000 tons (44,092,452 lbs) or even more in some cases.

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.

Long trains take longer time to stop than a single car because the braking effort is not synchronized.

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.

Modern trains have lots of stuff underneath. Motors, gearboxes, big boxes of power electronics, etc, etc. There is very little spare room under many trains, and chances are something will grab you and bundle you up into a disorganised mess of broken limbs. You probably won't die straight away, it'll take a while.

The mechanism of an emergency brake may differ, depending on railcar design. Emergency-braking a train (without track brakes) will give about 1.5 m/s2 (0.15 g) deceleration. The braking distance will be approximately 250 m (820 ft) at 100 km/h (62 mph) and 600 m (2,000 ft) at 160 km/h (99 mph).

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.
