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.

Santie Oil stocks train engine oil in 40–60-gallon drums or 40–260-gallon totes to help diesel mechanics keep locomotives in top condition. The Federal Railroad Administration requires train engine oil to be changed every 180 days (formerly 92 days), and the time may be extended based on the oil's condition.
How many gallons of gas does a train hold? An SD40–2 locomotive - a 3,000 HP standard line-haul workhouse of the past used by most North American RR holds 3,200 to 4,000 gallons of fuel. A typical switching locomotice - EMD MP 1500 - a 1,500 HP standard switching locomotive will hold 1,100 to 14,00 gallons of fuel.
Typical tank capacities start at 10,000 gallons for high density liquids and range up to 30,000 gallons for liquids having densities of around 6.5 pounds per gallon - lighter than water. Many tank cars have a downbuckle, or bend, in the center to help the fluid funnel downward for bottom unloading.
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.
As more new locomotives are being added to the fleet, the older ones are moved to other less demanding tasks, like moving railcars in a hump yard. Many locomotives can last 30–40 years, depending on the maintenance done on them. Our GG1 Lasted 41 years, but many of the steam locomotives were retired early.
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.
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.
Even when switchyard locomotives are not moving trains, their diesel engines are usually kept running. This is done to charge batteries, warm engine fluids and meet other operational needs. This can amount to several thousand hours of idling per locomotive each year.
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.
The average age of Amtrak passenger train cars is 19.4 years. If the distribution of ages is normal and of the cars are older than 22.8 years, find the standard deviation.
According to the AAR, moving freight by rail is 3 - 4 times more fuel efficient than moving freight on the highway. Efficient use of fuel means fewer greenhouse gas emissions for our planet. (Learn more at the Association of American Railroads' website, http://www.aar.org/.)
The 2022 CSX system-wide train efficiency metric, as shown above, equals approximately 520 ton-miles per gallon. In other words, CSX trains, on average, can move a ton of freight nearly 520 miles on a gallon of fuel, based on our 2022 revenue ton miles and 2022 fuel use.
