This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
The third rail can be on either side of the main running rails, and can be identified by a gray cover guard. In safety training, transit workers are instructed to never walk between the third rail and the main running rail. Climb back onto the platform if possible.
Where is the third rail on a subway track?
The third rail is usually located outside the two running rails, but on some systems it is mounted between them. The electricity is transmitted to the train by means of a sliding shoe, which is held in contact with the rail.
What happens if you touch the 3rd rail?
– The ‘third rail’ looks like a normal railway rail, but is electrified. The electricity is so strong that if you touch the rail, you will be seriously injured or killed. – The third rail and overhead lines have electricity flowing through them at all times and are never switched off.
Which one is the 3rd rail?
The third rail, also called 3rd rail or conductor rail, is a type of contact rail. A train with electric energy as the main power runs on a railway composed of two steel rails. In order to supply power to the train, a live rail is added next to the railway, which is the third rail.
Can you walk on train tracks?
Railroad tracks are private property, not public trails. It’s illegal to walk on the tracks unless you’re at a designated crossing. It’s extremely dangerous to walk, run, or drive down the railroad tracks or even alongside them. … Trains can’t stop quickly to avoid people or vehicles on the tracks.

Which is better third rail or overhead?
As a solid composite rail running along the track, a third rail is more rugged than an overhead contact wire and has a longer life expectancy. … A study performed for Dubai Metro found that a 1.5kV dc third rail traction system can also cost up to 13% less than a 750V dc third rail system.
Has anyone ever survived the third rail?
Andy Morris hit an electrified third rail after being shoved onto tracks during a drunken fight. A down-on-his-luck construction worker survived a 625-volt zap to the head after getting pushed onto an electrified third rail during a drunken brawl in Brooklyn.
Can you get electrocuted by peeing on the third rail?
There have been plenty of reports of death while peeing, but few have confirmed that the pee-to-rail contact was the actual cause of death, rather than electrocution for touching a 600-plus-volt line. A 1967 news story suggests it happened, but the coroners don’t sound certain of the cause of death.
Can you survive the 3rd rail?
People have even survived after coming in contact with the third rail, as long as they are not touching the running rail and third rail at the same time, he said. “When people are really smoked down there, it’s when you hit a running rail and the third rail at the same time,” he said.
Is the third rail always live?
Third rail systems are always supplied from direct current electricity. Trains have metal contact blocks (‘contact shoes’) which make contact with the conductor rail. … Tapered rails are provided at the ends of each section, to allow a smooth engagement of the train’s contact shoes.
What Does touching the third rail mean?
Touching a third rail can result in electrocution, so usage of the metaphor in political situations relates to the risk of “political suicide” that a person would face by raising certain taboo subjects or having points of view that are either censored, shunned or considered highly controversial or offensive to advocate …
Can subway rails electrocute you?
The city’s subway tracks are lined with a lethal third rail, which powers subway cars with enough electricity to kill a person in an instant. … In safety training, transit workers are instructed to never walk between the third rail and the main running rail. Climb back onto the platform if possible.
Can you lay down on train tracks?
So the answer is yes – it is possible to survive lying under the oncoming train, but it is very unlikely that you could survive that without a major injury. It is a good idea to stay away from railroad tracks. Just by hanging around such places you are putting yourself in danger.
What should you do if you fall in a train track?
Lie down between the tracks, depending on the depth of the tracks. Get to the side of the track. Step between the girders that separate tracks (but this involves stepping over the third rail, which carries more than 600 volts of electricity). Try to outrun the train as it stops in the station.
Why does O scale have 3 rails?
In the early days of railway modeling, some O scale modelers (the dominant scale at the time), made use of an outside third rail and a shoe pickup system for power. This system had the benefit of being more realistic by removing the central third rail common to O scale track, while retaining an effective power source.
How many people have died from the third rail?
Since 2008, 41 individuals were fatally struck by trains or died of other causes on the elevated, subway or at-grade right of way, records show. In addition, 11 people were electrocuted by the 600-volt third rail that sits alongside the tracks of the 224.1-mile CTA system.
Is it safe to pee during a thunderstorm?
Very hard, perhaps impossible, to kill yourself by peeing on high-voltage things. A toilet is probably as safe a place as any in a lightning storm, if you’re not touching metal. … If you have metal plumbing instead of PVC, lightning can follow the pipes through your walls and give you a good (perhaps fatal) jolt.
What happens when u pee on a worm?
What is urinary schistosomiasis and how is it treated? Urinary schistosomiasis is a disease caused by infection of people with the parasitic worm Schistosoma haematobium. These worms live in blood vessels around the infected person’s bladder and the worm releases eggs which are released in the person’s urine.
Can you get electrocuted while peeing?
A stream of urine quickly separates into individual droplets, according to the television program “MythBusters.” Because the urine isn’t a steady stream, it would be highly unlikely that a powerful electric current could travel up it.
What happens when you put a penny on a railroad track?
A penny left on a track does not typically derail a train. A train speeding along its track is a very heavy object with an immense amount of momentum. The penny is simply too light to do much of anything. It is flattened or knocked out of the way by the train.
Do trains run on AC or DC?
Railways and electrical utilities use AC for the same reason: to use transformers, which require AC, to produce higher voltages. The higher the voltage, the lower the current for the same power, which reduces line loss, thus allowing higher power to be delivered.
Which traction system is best?
In case of heavy trains that require frequent and rapid accelerations, DC traction motors are better choice as compared AC motors. DC train consumes less energy compared to AC unit for operating same service conditions.
Why do trains use DC power?
DC motors are used on trains is because of their high torque and good speed control. Compared to AC motors, DC motors can provide industry applications with a fine balance of strong starting torque and controllable speed for seamless yet precise performance.
Is it illegal to put pennies on train tracks?
To get to the subject, is it legal to put coins on a railroad track? Placing pennies on a railroad track is in fact illegal. The railroad tracks are private property, so doing that is considered trespassing.
