Much depends on the loco type/class/load, I'm sure, since answers range from 7 to 22 hours and 550 to 1650 miles. (Those work out to about . 4 miles per gallon, which is actually a -lot- more than I would have guessed!)

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.
Yes, diesel engines are always running in case you didn't know! We don't see any other type of train doing this, but only diesel locomotives leave their engine running always. In case you haven't noticed, diesel trains are never turned off. They are always left running.
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.
Large 4000 to 6000 HP mainline freight locos will usually have a 4000 to 5000 gallon fuel tank under the frame between the power trucks. How many miles per gallon does a train get? How far can a train go on a full tank of fuel? CSX trains, on average, can move a ton of freight nearly 500 miles on a gallon of fuel.
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.
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.
The life expectancy of diesel-electric and electric locomotives is expected to be similar—about 25 years. Both types of motive power are subject to technological obsolescence.
Complying with professional and federal rules and regulations relating to train operation and safety. Monitoring the speed, air pressure and other operational measurements of the train. Using mechanical controls such as throttles and air brakes to control the speed and motion of the train.

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.
One locomotive weighs about as much as 108 hipposTier 4 locomotives weigh a whopping 432,000 pounds — the same as 108 hippos weighing in at 4,000 pounds each. These 6-axle engines have 4,400 traction horsepower and can reach a maximum speed of 70 miles per hour pulling thousands of tons of freight.
One of the primary reasons railroads use distributed power is to increase the pulling power of the trains as the length and weight also increases. By placing additional locomotives in the middle or at the end, the overall pulling power of the multiple locomotives increases, moving the train efficiently and effectively.
Rail Tank Car Fun FactsTypically, tank cars have up to five times the capacity of truck, holding between 6,500 gallons to more than 31,000 gallons of liquid.
