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 . Being a volatile fluid care must be taken for its storage and handling losses.
Today's train locomotives are already quite fuel efficient, especially compared to trucks. In fact, trains can haul one ton of goods an average of more than 480 miles on just a single gallon of fuel, making them 3-4 times more fuel efficient than trucks.
Biodiesel & Renewable Fuels: Traditionally, locomotives have run on petroleum diesel fuel, but railroads are now using renewable diesel and biodiesel blends to power them. Both renewable diesel and biodiesel are made from renewable energy sources and don't rely on fossil fuels.
Idling switchers use between 3 and Il gallons of fuel per hour depending on the ambient temperature. If a switcher idles 12 hours a day in warm weather and burns 3 gallons of fuel per hour, it would consume 36 gallons of fuel per day.
Train engines generate thousands of horsepower and take an hour or more to warm up before they can start pulling rail cars. This is one reason there is reluctance to turn them off. Also, particularly relevant for a locomotive attached to a train, the brakes on the cars in the train do not work without power.
Are trains more efficient than cars and planes? If you mean energy efficient, yes, trains are far more energy efficient than cars (because they carry so much more people and freight) and planes (who spend so much energy to get 30K feet into the air.)
For a fuel cost of $0.84 per liter of diesel ($3.17 per gallon) (AAR (2012b)), this results in an average running fuel cost of $185 per locomotive-hour. If actual train and operation data are available, energy models or rail simulators may provide more accurate fuel use values for specific conditions.
A train engine requires about a hundred litres of fuel to get it started. So it wouldn't be economical if the engine is stopped and started frequently. This apart, if the engine is stopped, the moving parts' lubrication will also come to a halt.
BNSF Locomotives. We have one of the newest locomotive fleets in the industry. A typical BNSF locomotive will travel up to 4.8 million miles in its lifetime - equal to about 20 trips from the earth to the moon.
Freight trains are several times more energy-efficient than trucks, because 1) the rolling resistance of the steel wheels of trains is lower than that of truck tires on the road, and 2) trains encounter less proportional wind resistance than trucks since a train car is partly shielded from the headwind by the car in ...
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.
