The system’s 214 electrical-power substations receive high and low-voltage electrical current from the New York Power Authority. Substations may receive as much as 27,000 volts from the power plants and then convert it for use in the subway. The subway’s contact (third) rail requires 625 volts for operating trains.
Are subway Systems electric?
On subway trains, the third rail is the source of the electrical delivery system. The same power is delivered to light-rail lines such as the Blue, Gold, Green and Expo lines via an overhead catenary system. No petroleum gas for the trains.
Do subways run on gas or electricity?
Subways get their power through an exposed electrical line known as the third rail, which runs alongside the two rails the train cars ride on. Subways do not use gas-fueled combustion engines because the exhaust in the enclosed subway tunnels and stations would cause carbon monoxide poisoning to riders.
When was the NYC subway electrified?
Initially the surface and elevated railroad lines ran on steam power, but between 1893 and 1900 the lines were converted to run on electricity. An exception was the service on the Brooklyn Bridge. Trains were operated by cables from 1883 to 1896, when they were converted to electric power.
How much electricity does NYC subway use?
A 10-car subway train in New York’s system might require a jolt of three to four megawatts of power for 30 seconds to get up to cruising speed, according to Louis Romo, vice president of sales at Vycon. That’s enough to power 1,300 average U.S. homes.
How is the NY subway powered?
The system’s 214 electrical-power substations receive high and low-voltage electrical current from the New York Power Authority. Substations may receive as much as 27,000 volts from the power plants and then convert it for use in the subway. The subway’s contact (third) rail requires 625 volts for operating trains.
What part of the subway is electric?
the third rail
Energized at 600 volts DC, the third rail provides electrical power to the power-train, and ancillaries of the subway cars.
What fuel do subways run on?
Although trains started with steam engines, they have since evolved into efficient engines that run on diesel, gas, or electricity.
What power do subways use?
DC power
Subways are a form of light rail which uses tunnels to find a right-of-way in dense urban areas. Most subways use a third electrified rail to supply DC power.
How do Metro trains get electricity?
Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings, or a third rail mounted at track level and contacted by a sliding “pickup shoe”.
How would you survive if you fall on subway tracks?
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.
How deep is the New York subway?
Subway water tunnels are built approximately 30 feet below the riverbed. Because of the immense pressure exerted by 30 feet of rock, sand, and silt, plus 50 feet of water, such tunnels were in danger of collapsing.
How fast do NYC subways go?
| New York City Subway | |
|---|---|
| Electrification | Third rail, 600–650 V DC (normally 625V) |
| Average speed | 17.4 mph (28.0 km/h) |
| Top speed | 55 mph (89 km/h) |

Where does NYC get most of its electricity?
Hydropower. NYPA operates generating facilities throughout the state. More than 70 percent of the power we generate is clean hydropower.
How does Manhattan get electricity?
Today, New York gets its power from hundreds of fossil-fueled power plants and hydroelectric facilities, a handful of nuclear plants, and, increasingly, solar and wind installations.
How much water is pumped out of the NYC subway?
about 14 million gallons
Bored through layers of rock, the subway system snakes through stopped-up natural springs and is surrounded by the groundwater that runs beneath the city. In fact, about 14 million gallons of water are pumped out of the system on a dry day.
Is the New York subway driverless?
Most trains on the New York City Subway are manually operated. As of 2022, the system currently uses Automatic Block Signaling, with fixed wayside signals and automatic train stops.
Can you survive under a subway train?
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.
Which rail is electrified in NYC?
Watch the third rail.
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. The third rail can be on either side of the main running rails, and can be identified by a gray cover guard.
Are modern trains electric or diesel?
No modern train uses a diesel engine to power their wheels directly. They’re used as generators to power electric motors. So the only difference boils down to where the electricity comes from. And even in the most train-friendly countries like France and Japan, huge sections of the network are not electrified.
Are most trains diesel or electric?
Freight and passenger rail rely almost exclusively on diesel power. The latest diesel innovations contribute to cleaner air and reaching climate goals. According to the Association of American Railroads, in a typical year, US freight railroads move around 1.7 billion tons across nearly 140,000-miles of track.
