Do train cars have their own brakes?

Each rail car has its own brake system. The brake components include a brake cylinder, brake shoes, a dual air reservoir, and a control or AB valve. The AB valve is used to route air from the reservoirs (auxiliary and emergency) to the brake cylinder.

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.

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.

Before the air brake, railroad engineers would stop trains by cutting power, braking their locomotives and using the whistle to signal their brakemen. The brakemen would turn the brakes in one car and jump to the next to set the brakes there, and then to the next, etc.

Train brakes work off of air pressure, he said. Each car in the line has a pipe running along its undercarriage, and those pipes are connected by hoses where the cars meet. Then, before the train departs, that pipe system is pressured to 90 psi, said Udolph, who was a train engineer earlier in his career.

When such electronically controlled brakes fail, she said, trains become immovable and it can cause major disruptions. So railroads instead space locomotives throughout a train, which can more quickly distribute a brake signal among cars than a single locomotive can, Kahanek said.

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.

Some train drivers are changing sanitary towels in bushes by the side of the track – that's outrageous in a first world country in 2021. Others urinate or defecate into carrier bags and bottles.

The position of the train driver differs from that of the conductor in that the former is in charge of running the locomotive while the latter manages the cars, including the crew, passengers and their activities.

“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.”
