A locomotive’s diesel engine is connected to an electric generator that is either DC or AC. In either case, the power produced is around 3,200 horsepower. The generator uses this power to convert it into a massive amount of current, approximately 4,700 amperes.
How much horsepower does a train engine have?
“Most electric locomotives weigh between 100 and 200 short tons (90 and 180 metric tons) and provide about 6000 to 7000 horsepower (4500 to 5200 kilowatts).”
What is the most powerful train engine in the world?
All hail Mother Russia: with 17,838 horsepower, the Novocherkassk 4E5K locomotive is the most powerful in the world.
How much torque does a train engine have?
Generally, how much torque does a train engine have? – Quora. Ok a 710–16 2 stroke EMD makes about 4600 HP at 900 rpm’s. HP = (T * RPM)/5252 si solving for torque is gonna give you 26,843 ft-lbs of torque! That’s a lot of torque.
What fuel do trains use?
Freight train engines rely almost exclusively on diesel. The first over-the-road diesel freight engines entered service in the 1930s and the number of diesel-powered trains in the U.S. surpassed 1,000 in 1940 – most for passenger service.
Why do trains have 2 engines?
Advantages. Double heading is practised for a number of reasons: The most common reason is the need for additional motive power when a single locomotive is unable to haul the train due to uphill grades, excessive train weight, or a combination of the two.
Why train engines are not turned off?
Trains, being large and heavy, need the optimal brake line pressure for its efficient stopping. For obvious reasons, loco pilots never compromise on brake line pressure. Another reason for not turning off diesel train engines, lies in the engine itself. … A train’s diesel engine is a large unit, with around 16 cylinders.
How many rail cars can a train pull?
How Many Train Cars Can An Engine Pull? The number of wagons can vary from 40 to 46 depending on the track gradient and other constraints, such as the length of passing loops, loading and discharging loops, and sidings. In typical operating conditions, each locomotive can pull 20 to 23 fully loaded wagons.
What is the longest train ever?
An interesting feature published by The Telegraph took a look at the longest direct rail routes that do not involve changing train. The Trans–Siberian Railway which connects Moscow with the Russian far east is still the world’s longest direct rail route, running for 9,259 kilometers or 5,753 miles.
What powers trains now?
A closer look at trains all over the world reveals that it’s indeed unfair to mock US trains for being diesel. No modern train uses a diesel engine to power their wheels directly. They’re used as generators to power electric motors.
How heavy is a train engine?
|Loco weight||423,000–432,000 lb (192,000–196,000 kilograms) 212–216 short tons (189–193 long tons; 192–196 t)|
|Fuel type||diesel fuel|
|Fuel capacity||5,500 US gal (21,000 l; 4,600 imp gal) or 6,200 US gal (23,000 l; 5,200 imp gal)|
|No. of traction motors||GE GEB13 AC|
How fast does a freight train go?
Trains carrying freight are currently allowed to travel at speeds of up to 70 mph or 80 mph, but unloaded many trains generally only travel from 40-50 mph, according to FRA researchers.
How many mpg do trains get?
Thanks in part to these technologies, today U.S. freight railroads can, on average, move one ton of freight more than 480 miles per gallon of fuel, making rail an environmentally friendly way to move freight over land.
How long does a train engine last?
In general, the period between overhauls for our road locomotives is eight to 10 years. During an overhaul, the engine and alternator are rebuilt or replaced and any wear and tear on the body is repaired.
