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.

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.
The Federal Railroad Administration does not currently set any limits on train lengths – and also doesn't regularly track train lengths or their associated risks. That has allowed freight railroad companies to occasionally operate trains up to 8 kilometres (5 miles) long.
What happens if you stand too close to a train? Air between person and the train moves with high velocity due to dragging effect and the air behind person is approximately still.
There are many reasons why Americans don't ride the rails as often as their European cousins. Most obviously, America is bigger than most European countries. Outside the northeast corridor, the central Texas megalopolis, California and the eastern Midwest, density is sometimes too low to support intercity train travel.
The planet's longest train trip would come to around 18,755 kilometres, take three weeks, travel through 13 countries and require at least seven different visas. Certain rules were taken into account. There should be no pointless back-and-forth between two places and no transfers to boats or planes (duh).
The Trans-Siberian is the longest passenger train in the world and travels across China, Mongolia, and the famous, beautiful Siberia. Have you ever considered cruising over 10,214 km for seven days and 20 hours, crossing two continents and a whopping eight time zones?
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.
CLIMATEWIRE | The first U.S.-made high-speed bullet trains will start running as early as 2024 between Boston, New York and Washington, with the promise of cutting transportation emissions by attracting new rail passengers who now drive or fly.
That's because the noise a train makes is mainly projected to either side. When trains are moving directly towards you they are barely audible–until it's too late.” He adds: “It's surprisingly easy to overload the brain to the point where it can't triangulate where sound is coming from.”
