Why do trains not have brakes?

Brakes exist, but they're limited in their power These are typically controlled by the engineer. They're simply a faster way to aggressively slow and stop the train when needed. Some passenger trains, like subway systems, have emergency brakes for passengers. For freight lines, though, the engineer controls the brake.

Locomotives are equipped with 2 air brake systems: automatic and independent. The automatic brake system applies the brakes to each locomotive and to each car in the train as well; it is normally used during train operations to slow and stop the train.

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.

Trespassing on the railway is illegal and dangerous. You could be taken to court and face a £1,000 fine. For this reason, when we see someone trespassing, we have to stop all trains in the vicinity to remove trespassers, check for damage and clear blockages.

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.

a magnet on the track, when the train runs over the magnet it will warn the driver to stop; a transmission loop that tells the train the signal is red, this will trigger the train computer to apply the brake.

Long trains take longer time to stop than a single car because the braking effort is not synchronized.

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.

MORE DETAILS

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.

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.

Never trespass or cross tracks illegally. It's illegal and dangerous to walk on or near tracks unless you're using a designated crossing. It's also illegal and extremely dangerous to drive around closed crossing gates or to ignore flashing warning lights.

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.

“People assume that trains are loud, but that assumption is based on the fact that when a train's gone past them in a station it's noisy. 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.”
