10 Largest Locomotives ever built

"Few machines are as impressive as locomotives, with their sleek appearance and staggering hauling power. Steam-powered locomotives were the first type of locomotives built, ushering in a new industrialized era with promises of more efficient cargo hauling and passenger travel. These locomotives were often extremely durable, with some of them even running to this day.

So just how large can steam locomotives get? There are plenty of different factors that can be taken into account while determining a locomotive’s overall “size,” including everything from length to traction effort and horsepower. Today, however, we’ll be ranking the 10 largest steam locomotives ever built according to their weights in order to see how they compare.

Apparently the strongest European fast train steam loco was from Austria and produced under license in Rumania.

The Top 10 list shows the Big Boy as second. I've heard that the Big Boy is not the strongest steam loco, nor the longest or heaviest. Still it is an impressive loco and an impressive model.
Thanks for sharing the list.

Wikipedia writes they were the strongest of their time. Makes me wonder if there was a stronger one later on.

I think there is always going to be some controversy or debate on many aspects of the biggest, longest most powerful etc. Every country has its favourite locos and wants to promote them all.

Same as the record speeds recorded, some say other trains did 150 mph but was not recorded as a record attempt etc. All the steam era trains are magnificent regardless of position on the worlds best whatever list

Some BIG Russian locomotives are also worth mention

Like the P38 2-8-8-4 (lightweight version of the Yellowstone)


and the class AA20 4-14-4

Note the middle 3 drive wheels are flangeless.

For further reading: 8 of Russia’s strongest, fastest, and biggest steam locomotives



And for narrow gauge, the Henschel 2-8-8-4 is worth mentioned. Henschel built 4 for a Brazilian railway
http://vfco.brazilia.jor.br/vapor/locomotivas/locomotiva-Henschel--2-8-8-4-num-1307-EFCB-Goias.jpg They were the only narrow gauge locomotives of this wheel arrangement. They had the largest boilers ever used on a narrow-gauge Mallet.

The Big Boy was one of the most successful large steamers, but not the largest by several measures. The Yellowstones and the Y-Class were massive in both size and power but they were drag locos that pulled long ore/coal trains at very low speeds. Several steam locos made more drawbar HP than the Big Boy and a few were longer, although I would need to do some research to enumerate them.

What is so impressive about the Big Boy is that even with all of that power they were able to safely run up to 130 kph and were capable of occasional operation at even higher speeds. They were normally used to pull long and heavy trains over mountainous terrain at high speeds without a helper. The technology that allowed a large articulated loco to run so fast with good tracking was developed by ALCO and UP with their very successful Challenger. UP then went on to expand on the Challenger concept to create the Big Boy and a shop worker with some chalk made history with his flippant name for this beast.
Regards,
Jim

I have almost all Märklin and mostly HO, although I do have a small number of Z gauge trains!
I have models from Era I to Era VI, but I try to focus on Eras I & III. Whoops, that one got away from me. Let's just say I focus on cool trains, regardless of the particulars :-)
So many trains and so little time.

I've often wondered though, were US steam locomotives larger in general than most locomotives of the same type used in mainland Europe? Assuming that most of the models I have are at least close to being accurate in scale, the few remaining US steam locos I have are noticeably larger than similar German steam locos I own. For example, the brass Southern Railway (US) Ps-4 I own, which is based on the USRA Heavy Pacific design, is larger in every dimension than my BR-01. My guess is that the tunnels initially dug in Europe were never enlarged over time, and locomotives had to be built to fit, while tunnels are much less common in the US, and those that were built were either dug larger initially or enlarged later.

Maybe one day I'll start another thread, and take some photos...

Indeed, most publications explain the size difference between European and US rolling stock by the difference in available space. See the article about loading gauge on Wikipedia.

For me is the biggest loco at this list #10. Exceptional a new class of locos: the electrical steamer!

The Norfolk & Western wh(Y)-class!LOL LOL LOL

Its not a new class, the Swiss have actually done it

The www.douglas-self.com is actually a quite interesting site, espesially the Unusual Locomotives page
Some examples:
