If you touched the third rail and the ground, briefly (a fraction of a second), you might survive. Wikipedia claims that: Shocks above 2700 volts are often fatal, with those above 11000 volts being usually fatal. Shocks with voltages over 40,000 volts are almost invariably fatal.
Well, trains do not have gear box with shifting gears. They have basic two gears, on the axle of the wheel. One is the main gear and other is the pinion gear. The pinion gear is attached to the traction motor and the main gear is attached to the main wheel.
The average fuel consumed per kilo- meter for all passenger and cargo trains is 7.97 L/ km. This value for local, trafficking, railway track laying and maneuvering trains is 7.92 L/km.
Some use their diesel engine to generate electricity to work motors linked to the wheels. Valley Lines electrification would significantly improve journey times because electric trains would accelerate faster than diesels from the network's frequent station stops. Electric trains also perform better on steep gradients.
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electric railways use either electric locomotives (hauling passengers or freight in separate cars) or electric multiple units (passenger cars with their own motors).
Most of the world's high-speed trains (German ICE, French TGV, Japanese Shinkansen etc) are powered by electricity. Diesel traction is used in some places, obviously where the network is not electrified. This usually happens when existing routes are upgraded for higher-speed running.
So, How much do locomotives cost? A diesel locomotive could cost from $500,000-$2 million. While an electric locomotive could cost more than $6 million. Price depends on whether it is powered by AC or DC traction, how much horsepower it has, or what electronics it is equipped with.
Electric trains are trains that are powered by electricity. Their power comes from a power station that sends electricity to the electrical third rail built onto train tracks. The sliding shoes transfer electricity from the third rail to the train.
One unit can easily pull 100 cars on the flat if you only want it to go 10-12 mph. Put it on a 2% grade and a 3000 hp unit can only pull about 6-8 cars at about 15 mph. Western RRs usually rate their trains in Horsepower/ton.
Making all that commerce move down the track are train locomotives. But some of the locomotives face backwards as they move down the tracks, seeming to one 2News viewer that they are being inefficiently dragged down the tracks. Thus, the direction of the locomotive makes no difference to efficiency or safety.
According to the designers, diesel engines could run faster and work longer than steam locomotives. They used a vast amount of energy to build up steam pressure, which had to be discarded whenever the locomotive stopped or shut down. In every week of operation, a locomotive consumed its own weight in coal and water.
A Brief History Of This Engine
The Union Pacific Centennial is the largest and most powerful diesel locomotive ever built.trains became heavier and faster, cooking in a caboose became too hazardous and motels made lodging in the cars unnecessary. Today, the cabooses are being phased out as quickly as labor agreements and railroad operations permit. Most carriers are donating the cars or selling them at prices equal to their scrap value.
Currently, with what information is published, the most powerful articulated and single unit locomotive is the 2ES10S (3ES10), the strongest-pulling is the IORE, and the heaviest is the Union Pacific Coal GTEL.
Track classes
| Track type | Freight train | Passenger |
|---|
| Class 5 | 80 mph (129 km/h) | 90 mph (145 km/h) |
| Class 6 | 110 mph (177 km/h) |
| Class 7 | 125 mph (201 km/h) |
| Class 8 | 160 mph (257 km/h) |
Another reason for not turning off diesel train engines, lies in the engine itself. It is also interesting to know that while diesel locomotives are idling, fuel consumption is more than when the train is moving. This is because, while idling, the batteries are being charged, and the air compression is in operation.
This efficiency might be stated as “a truck can move a ton of freight 134 miles on a gallon of fuel.” Similarly, a typical train might haul 3,000 tons of freight 500 miles and consume approximately 3,049 gallons of diesel fuel.
In May 2017, railroad conductors received a median salary of $60,300; earnings for the lower half of conductors fell below this amount, and earnings for the top half were above it. The bottom 10 percent of conductors made below $42,950 annually, while the top 10 percent earned high salaries over $91,630.

How much does a train engine/locomotive weigh? The average locomotive weights around 210-220 tons (465,000 - 480,000 lbs).
Tier 4 Locomotives. Tier 4 locomotives reduce emissions between 65% and 85% compared to legacy Tier 2 and Tier 0 locomotives in Metrolink's fleet. Tier 4 locomotives began phasing into service in fall 2017.
This jaw-dropper is the Wärtsilä RT-flex96C, the world's largest and most powerful diesel engine. Built in Finland, the RT-flex96C's fourteen cylinders can generate 107,389HP with more than 7,000,000Nm of torque — that's enough to power an entire suburban town.
One unit can easily pull 100 cars on the flat if you only want it to go 10-12 mph. Put it on a 2% grade and a 3000 hp unit can only pull about 6-8 cars at about 15 mph. Western RRs usually rate their trains in Horsepower/ton.
The fastest steam locomotive was the A4 'Mallard' 4-6-2 and could reach 125 or 126 mph. According to the 1997 Guinness Book of World Records, the French TGV had the highest average speed from one station to the next of 253 kph (157 mph).
The weight is needed for traction, that is why locomotives of any type can haul so much tonnage is because of their heavy weight that allows proper adhesion of the wheels to the rails for traction. It takes a huge amount of weight to keep those steel wheels from slipping on that steel track.
