How quickly can a freight train 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).

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.

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.

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.

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).

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.

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 long noses are designed to reduce sonic booms in tunnels. Casablanca express: Africa's first, and so far only, dedicated high speed line carries trains at up to 320 kph (200 mph) between the port city of Tangiers and Casablanca.

The giant two-stroke, turbocharged engine and electrical generator provide the huge amount of power needed to pull heavy loads at high speeds. Cummins' locomotive engine weighs over 24,000 pounds (10,886 kilograms). The generator and electric motors add more mass on top of that.

Passenger trains carry people, while freight trains carry goods, raw resources, and even the mail. Because freight trains no longer need to carry passenger cars, engineers have changed their design. These changes mean that freight and passenger cars can no longer travel together.

Most Shinkansen trains operate at speeds of about 500 kilometers per hour (200 to 275 miles per hour). As new technologies are developed and instituted, future trains may achieve even greater velocities.
