How much did it cost to build Big Boy?
The name stuck and became the name of this locomotive type. ALCO built 25 of these locomotives for the Union Pacific at a cost of about $265,000 each. Based on inflation, the equivalent amount of money in 2018 would be $4,700,000 per locomotive.
“Nobody ever thought that a Big Boy would be restored to operation. Ever.” Union Pacific hasn't said how much the restoration cost, but Wrinn estimated at least $4 million based on similar restorations.
They were the only locomotives to use a 4-8-8-4 wheel arrangement: four-wheel leading truck for stability entering curves, two sets of eight driving wheels and a four-wheel trailing truck to support the large firebox. Today, eight Big Boys survive, with most on static display at museums across the USA.
Union Pacific 4014, also known as the "Big Boy", is a steam locomotive owned and operated by the Union Pacific Railroad (UP) as part of their heritage fleet. It is a four-cylinder simple articulated 4-8-8-4 "Big Boy" type built in 1941 by the American Locomotive Company (ALCO) at its Schenectady Locomotive Works.
Q: Why is a diesel with Big Boy 4014? A: The diesel serves many purposes. Its dynamic braking saves brake shoes. Its power provides a boost that saves on No.
John Bull is a historic British-built railroad steam locomotive that operated in the United States. It was operated for the first time on September 15, 1831, and became the oldest operable steam locomotive in the world when the Smithsonian Institution ran it under its own steam in 1981.
Sinara GT1s for Russian Railways, 11,285 horsepower
Since it debuted in 2008, the Sinara GT1s has held two very important titles: the world's most powerful gasoline turbine locomotive and the world's most powerful internal-combustion locomotive.
They weigh 1.2 million pounds, which means that any long-term forward motion necessitated their 56,000-pound coal capacity and their 24,000-gallon water capacity to perpetually push those massive pistons with steam. The girth required a 4-8-8-4 wheel configuration to keep that thing rock-steady on the rails.
It is generally agreed that the largest steam locomotives are the 4-8-8-4 'Big Boys', built by the American Locomotive Company in 1941-44. They are 39.852 m (130.74 ft) long and weigh 508.02 tonnes (1.12 million lb) with tenders.
It had a maximum power capacity of more than 6,000 horsepower and could haul a 3,600-ton train unassisted up the Wasatch Mountain grade. Pulling freight on level track, it could achieve a speed of 70 miles (112 km) per hour.
What is the most famous diesel locomotive?
What is the most famous diesel locomotive in the history of railroading? Arguably, the classic Electro-Motive “F-unit” can lay claim to the title. The Electro-Motive “F-unit”: Born in the autumn of 1939, it would be produced, in eight different models, until 1960 and would number more than 7,500 strong.
Twenty-five Big Boys were built exclusively for Union Pacific Railroad, the first of which was delivered in 1941. The locomotives were 132 feet long and weighed 1.2 million pounds.

The Big Boy consumed 74,700 lb (33,883 kg) of coal and 34,800 gallons (131,732 L) of water.
The most powerful steam locomotive currently in operation is the Union Pacific "Big Boy" 4014, a simple articulated 4-8-8-4 locomotive capable of a tractive effort (pulling force) of 135,375 lbf (602 kN) at 10 mph.
The Centennials were the largest diesel-electric locomotives ever built. Actually comprising two engines on one frame, they delivered 6,600 horsepower. Designed and built exclusively for Union Pacific Railroad, the units were named in honor of the railroad's centennial anniversary celebration in 1969.
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.
The Union Pacific Centennial is the largest and most powerful diesel locomotive ever built.
To begin with diesel locomotives were less powerful than steam engines which meant smaller train sizes (ie. e the amount of carriages they could tow) which you would have thought made them a less preferable option - so why make the switch?
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.
There are many websites to choose from that are dedicated to selling train cars and related materials. You can buy a caboose, a boxcar, or even a sterling rail. Some of these websites have full refurbished railroad cars listed as well.
What is the slowest locomotive?
The Glacier Express is the world's slowest train, taking more than eight hours to travel between Zermatt and St. Moritz in Switzerland at an average of 18mph. Along the way, it passes over nearly 300 bridges, travels through 91 tunnels and takes in endless stunning Alpine views.
Diesel engines continuously run 1,000,000 to 1,500,000 miles before major overhaul. They are 3 major reasons why they last so long: Design. Fuel.
8. The GM locomotive is highly fuel efficient having 11% better fuel efficiency compared to the ALCO design locomotive. 9.

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. Because of their great length, the frames of the Big Boys are “hinged,” or articulated, to allow them to negotiate curves.
How far could a steam locomotive go before needing water?
During the very early days of steam locomotives, water stops were necessary every 7–10 miles (11–16 km) and consumed much travel time. With the introduction of tenders (a special car containing water and fuel), trains could run 100–150 miles (160–240 km) without a refill.
Union Pacific Railroad ($UNP) is one of the largest and longest-tenured railroads in North America, having been founded in 1862. It currently operates over 8,000 locomotives across 23 of the Western United States.
In general, Caterpillar is regarded as the undisputed king of diesel engines.
