Which is better pantograph or third rail?
Pantograph Current Collector Less dangerous than a third rail system. No security is required as the conductors are above the ground level. The initial cost is more. Disturbance for other lines like telephone cables, low tension lines, etc.
What is 3rd rail system?
A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track.
What is the third rail on a railroad track?
The third rail on a railroad track is the steel bar which passes electric current to a train.
How much current is in 3rd rail?
750 volts
Train campaign. The third rail is probably one of the most difficult dangers to see. It looks just like an ordinary rail, but it carries 750 volts – easily enough to kill you. The DC current that flows through is three times as powerful as your home electricity.
Is third rail better than overhead?
offering high efficiency – a 750V dc system offers a power supply transmission efficiency average of 92-94%. 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.
What happens if you touch third rail?
But if you somehow end up on the tracks, the key is to avoid the third rail, which pumps out 600 volts of electricity. One touch can electrocute you–and potentially kill.
Do rats get electrocuted by third rail?
They dart over tracks and duck under the third rail, sometimes hopping atop it, sometimes scampering beneath. Even as the vibrations from approaching trains cause them to dart away, they avoid electrocution.
Can you touch the 3rd rail?
But if you somehow end up on the tracks, the key is to avoid the third rail, which pumps out 600 volts of electricity. One touch can electrocute you–and potentially kill. The third rail–the tallest of the three rails along the track–is located the farthest away from the platform for customer safety, Ziegler said.
