Why are trains left idling?
Engines may be left idling to maintain important safety related functions such as maintaining engine temperature, air pressure for the brake system, the integrity of the starting systems, the electrical system and providing heating or cooling to a train's crew and/or passengers.
The amount of fuel-dependency and the maintenance issues which come along with diesel engines are the primary reason for this. Though electric trains are far more efficient than conventional diesel engines, some still love the nostalgia factor which comes with trains making smoke.
Most early American railroads were designed by English engineers who brought with them expertise, equipment, and a left-side tradition. This is most likely why the theory arose that they were responsible for our left-handed system. However, the first double-track designs in the East were American style.
The reason trains stop, according to Bellamy, is because of a switch adjustment. “They have to pass the switch and then a carman or a switch man has to hop off and physically throw the switch (Bellamy described this as a lever on the ground) so that it changes the direction of the track.
Using an average of 3.5 gallons of fuel burned per hour idling per locomotive – some easy math shows an annual consumption of over 20 million gallons of excess idle, which is over 4% of the total annual fuel consumption for that particular Class I railroad – do we have your attention yet?
In a 2008 rulemaking (73 Federal Register 37096), EPA set stricter emissions requirements for locomotive engines built or remanufactured after 2012. It also required new locomotives to be equipped with an automatic engine start/stop system (AESS) that will shut down the engine after 30 minutes of idling.
Unlike car and truck engines, most locomotives in the U.S. are cooled with water that contains anti-corrosion inhibitors, but does not contain antifreeze compounds. Because of this, locomotive cooling systems may need to be drained when engines are shut down during road operation in cold weather.
As someone who works on the railroad, you've probably heard about the myth that a single penny or quarter could derail a train. The good news for you is that putting a penny on the tracks isn't likely to cause the train any trouble at all.
Trains aren't invincible though. A car, truck, or even a brick left on the track can lead to derailment. According to the Federal Railroad Administration, 1.4% of train derailments from 2009-2012 were caused by objects on the track. This group of causes includes snow, ice, and coal.
Never dump salt directly on railroad crossings. Salt causes circuitry wiring to short out, causing malfunctions to the lights and gates.
How sharp can a train turn?
Curves of 1 or 2 degrees are the most common on mainline railroads; the sharpest curve a common four-axle diesel can take is about 20 degrees when coupled to other rolling stock, more than 40 degrees when by itself. Mountainous territory, however, generally dictates curves of 5 to 10 degrees, or even sharper.
Trains regularly reach speeds of 125-150 mph (201-241 kph).
In rail transport, a derailment occurs when a rail vehicle such as a train comes off its rails. Although many derailments are minor, all result in temporary disruption of the proper operation of the railway system and they are a potentially serious hazard.
Fuel Tank. This huge tank in the underbelly of the locomotive holds up to 5,500 gallons (20,820 liters) of diesel fuel, plus an additional 300 gallons (1,135 liters) of coolant, and 250 gallons (946 liters) of engine oil.
Thanks in part to these technologies, today U.S. freight railroads can, on average, move one ton of freight nearly 500 miles per gallon of fuel, making rail an environmentally friendly way to move freight over land.

The Short Answer. Trains have multiple engines to provide more power to pull the train. Each locomotive has a certain amount of pulling power (called “tractive effort”), which is related to how many horsepower the diesel engine in the locomotive has.
There are no restrooms in railway engines, and there is no passage that leads to the long line of coaches it is attached to.
“Depending on the length of the train, as well as the length and number of tracks at a rail yard or customer facility, the train may have to move back and forth as it shoves cars into one track, backs out, and then moves forward to drop off or pick up cars on an adjacent track.”
Air displacement of a train in a tunnel can create noise from turbulence. Trains also employ horns, whistles, bells, and other noisemaking devices for both communication and warning. The engines in diesel locomotives and DMUs produce significant amounts of noise.
How loud is a train locomotive?
Conclusion. Locomotive horns are distinctive and loud. The lowest volume they can be is 96 decibels, and the highest volume they can be is 110 decibels. This means the sound can be as loud as a shouted conversation or as loud as a chainsaw.
Check that train windows, air-conditioning and vents are working correctly – nearly half our trains are air-conditioned with systems that draw in a full carriage worth of fresh air from outside every 6-9 minutes.
These are two solid steel plate fixed with Cattle guard. Those plate are fixed just above the rail track on locomotive. If Any thing small place on railway track then it will throw that out of the railway track. It is the first layer of safety.
"The electricity is so strong that if you touch the rail or step on it, you will stick to it like glue and won't be able to get off. "The electricity is likely to kill you - and, if you do survive, you will suffer terrible burns.
The crushed stones are what is known as ballast. Their purpose is to hold the wooden cross ties in place, which in turn hold the rails in place.
Trains also are safer than planes, in part, because many train stations have open-air platforms where travelers board, Dr. Aaron Rossi told USA Today in October. That's far less risky than the indoor settings of airport security lines and waiting areas where passengers gather and sit before boarding.
Thus, while drivers may have fewer hours for sleep in between successive work periods, they are likely to sleep more often in a single day and to be awake for correspondingly shorter periods. Relay van workers must also sleep in noisy crew-van carriages that shudder and vibrate along with the movement of the train.
And don't duck under the train, because most stations do not have enough clearance for the average human. And do NOT jump down onto the tracks to try to save someone else. The best thing you can do is run on the platform towards the tunnel where the train enters so you can get the operator's attention sooner.
Much depends on the size of the composition, because it varies according to the weight of cargo being added to the total weight of the composition (train) and the type of engine power and speed and he travels and the type of slope of the rail line can reach 50 liters of diesel per kilometer, or hours worked, because ...
Steam engines generally could run in either direction as well. They also had a reverser handle. Many diesel locomotives will have a small “F” or “R” letter on each end to indicate which end is the “forward” or “reverse” end.
What is the average of train engine?
The average figure ranges from 4 to 4.5 litres/ 1000GTKMfor passenger train and for goods train it is2. 25 to 2.75 litres/ 1000GTKM .
Similarly, a typical train might haul 3,000 tons of freight 500 miles and consume approximately 3,049 gallons of diesel fuel. The efficiency of this freight haul would be calculated as: (3000 tons x 500 miles) / (3,049 gallons) = 492 ton-miles per gallon.
