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.

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.
Why can't trains stop quickly? Because there's not much friction available in the wheel-rail interface. Normally this is a good thing, the low rolling resistance of trains is why they're so efficient at moving heavy loads.
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. An 8-car passenger train moving at 80 miles an hour needs about a mile to stop.
By the time a train operator sees you, it is too late to stop the train in time. An oncoming train is moving faster and is closer to you than it appears. Similar to an airplane traveling at 150 mph that appears to float onto the runway, it's hard to determine a train's speed and distance from you.
How Long Does It Take a Train to Stop? 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.
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.
No.The speed difference between the fastest aircraft and the fastest trains is about an order of magnitude. The atmospheric density at ground level would generate too much drag for a train to go as fast as a typical jetliner, let alone go supersonic.
With high-speed rail, train travel is always faster than driving. In many cases, it's even faster than flying, once you factor in the whole air travel song-and-dance. And if you do need to catch a plane, trains make it easier to get to the airport.
But statistically speaking, trains are actually a very safe way to travel -- much safer than driving. CNNMoney calculated how many people are killed for every one billion passenger miles traveled to compare the safety of different modes of transportation.
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.
If the person was struck by a train it is necessarily brought to an immediate stop. This leads to the line being blocked and possible subsequent delays to other trains in the area. The British Transport Police attend to take witness statements and determine if further investigation is required.
Every three minutes, a person or vehicle is struck by a train, according to rail safety advocates. As part of Rail Safety Weeks, drivers and pedestrians can learn to make safer decisions around train tracks. The number is staggering; the result, often deadly.
Fractured or crushed bones. Amputations. Spinal cord injuries, such as nerve damage and paralysis, affecting either one area or entire portions of a victim's body and leading to paraplegia or quadriplegia.
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.
NYC No. 999 4-4-0 was quite the speed demon for its time. The first locomotive to travel over 100mph, 999 hauled the Empire State Express and hit a world record speed of 112mph!
The middle of the train is by far the safest for persons. The National Transportation Safety Board does not release comprehensive data on where victims were sitting during fatal train accidents, though some details are available in individual investigative reports.
