How long do trains take to 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.

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).

The braking distance for high-speed trains (HST) operating over 200 km/h takes roughly over 6000 m and 1 minute 40 seconds.

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. There are brakes on every wheel, but it takes that long for all of those brakes to overcome the momentum of the tremendous weight pushing the train.

The way that it actually works, has a local reservoir on each car that is charged by the train line. When the train line reduces pressure, a purpose-designed valve allows a corresponding amount of pressure from the local reservoir into the brake cylinder. This positive pressure applies the brakes.

he brakes will be quickly applied. Typical noise levels due to air-brake operation range from 95 to 115 dB(A), in some cases as high as 120 dB(A).

Traffic lights, or rather trainline lights. Well before the train gets anywhere near the station it has lights that tell it to slow down, and stop. Depending on which lights are lit, depends on the drivers actions.

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.

What can stop a train in real life? The most common way is to use the brakes. The brakes are located on each wheel of the train and are applied by the train engineer. The engineer can apply the brakes manually or automatically.

Here in the UK passenger stock is normally limited to a maximum deceleration of 9% of 1G for normal braking (about -0.88m/s/s). In emergency braking that can go up to 12%G (about -1.18m/s/s). Some trams have track brakes that can stop a LOT quicker than that.

MORE DETAILS

When the train stops, there is no force acting on the object (passenger), so he will remain in motion. This is why when suddenly the train stops, due to the law of inertia or Newton's first law of motion, the passengers are pushed forward.

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 locomotive weighs about as much as 108 hippos These 6-axle engines have 4,400 traction horsepower and can reach a maximum speed of 70 miles per hour pulling thousands of tons of freight.

At night, most trains that aren't running are parked in the depot. Some trains park along the line, and some trains keep running all night and park during the day. When trains are parked, they're usually cleaned, checked, inspected, and maintained to prepare them for the next service.
