How many cars could a Big Boy pull?

The Big Boys were built for power. They did the work of three smaller engines, pulling 120-car, 3800 ton freight trains at forty miles per hour in the mountains of Utah and Wyoming. With power, though, comes weight - larger cylinders, pistons, drive rods, boiler and firebox.

Once the train is rolling, an engine with 110,000 lb tractive effort should be able to maintain 11-12 mph with at least 200 cars-- maybe 300 or more.

Rather, the term is more specific: A freight train can move one ton of weight about 450 miles on a single gallon of gas. To match this mileage, a one-ton car would have to get 450 mpg, and a two-ton vehicle would have to get 225 mpg. To car owners, this seems unbelievable. How can railroads do it?

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.

Each one cost approximately $265,000 to build, or about $4.4 million in today's money. In the railroad world, the Big Boys were known as 4-8-8-4 articulated type locomotives.

Twenty-five Big Boys were built exclusively for Union Pacific Railroad, the first of which was delivered in 1941. Of the eight remaining Big Boys in existence, No. 4014 is the only one operating today. The Big Boys were about 133 feet long and weigh 1.2 million pounds.

If the diesel engine referenced is the modern diesel electric locomotive that has been accompanying 4014 in its travels, my understanding is that Union Pacific utilizes it to assist with overall fuel efficiency and to provide regenerative braking. This helps with operating costs and provides a better level of safety.

The Big Boy has the longest engine body of any reciprocating steam locomotive, longer than two 40-foot buses. They were also the heaviest reciprocating steam locomotives ever built; the combined weight of the 772,250 lb (350,290 kg) engine and 436,500 lb (198,000 kg) tender outweighed a Boeing 747.
