Why do trains take so long to stop?

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.

For trains the wheels and the rail are both steel, and the steel-steel friction coefficient is around 0.25. So the stopping time and distance will, at best, be three to four times greater than a car.

“There are times when mechanical and operational issues could also result in trains occupying a crossing for extended times,” the email continued, “and when trains stop for mandatory safety inspections or federally regulated crew changes.”

Amna Nawaz: Freight trains are getting longer and longer in the U.S., some stretching for two or three miles. These longer trains allow for more goods to move more efficiently, which lowers fuel use and costs for the railroads.

Trains can't stop quickly. A freight train can take up to a mile to come to a complete stop. A locomotive engineer who suddenly sees someone on the tracks is not be able to stop in time.

In the United States it is the law, same as if involved in a vehicle to vehicle accident or accident with a pedestrian on the road is the same on the railroad, the law and railroad operating rules always require stopping the train after an accident or incident and rendering aid to injured people.

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).

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.

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.

It can happen. Servicing and/or crew change stations often have a lot of built-in time in the schedule. It's pretty common to see the servicing not take the full time, thus allowing some made-up time.

Trans-Siberian is the longest train trip in the world at seven days long. It travels 10,214 km across 16 major rivers, 876 stations, and 87 cities. Some long train trips – like the Canadian from Toronto to Vancouver – begin and end with overnight stays in luxurious hotels.

Currently, the world longest single continuous train journey with no changes is the daily service from Moscow Yaroslavsky to Vladivostok. The train journey is 167 hours long, covering a distance of 9,289 km and crosses 8 time zones.

“No Show” Policy: After departure, all fares are non-refundable and cannot be changed. Passengers who do not show or cancel prior to departure forfeit the entire amount of the no show trip segment.

The intensity of sound will vary at night, sometimes louder and sometimes softer. It has to do with the height and strength of a temperature inversion just above the ground. On clear, calm nights, it is cooler at the ground than higher up.

The reason that trains honk their horns so much at night is because it's dark and the trains aren't so easy to see. Even though the lights are on, we sometimes can't see them coming, especially around the many blind curves near or ahead of the train station.

Most American passenger trains travel on tracks that are owned by freight companies. That means most trains have to defer to freight services, leading to lengthy delays that scare off passengers who want to arrive on time. Domestic air travel in America is widely available, relatively cheap and popular.
