Superb presentation of this designation system! Thanks for posting this!

[@americansteamlegacy-yh9dr]

Hi FlyingSpirit. I'm glad you liked it!! Thank you for the compliment and thanks for watching!!

@@americansteamlegacy-yh9dr You are most welcome! Thanks again for all the work you did to prepare this; it will no doubt be invaluable to new rail fans (as well as to the rest of us!)

[@josephschuster1494]

My favorite wheel arrangement is the 4-6-4 Hudson (Baltic), specifically the New York Central, built in 1938 by Alco, a blend of massive power, speed and beauty. Truly a sweet locomotive!

[@americansteamlegacy-yh9dr]

Agreed!!! The NYC Hudsons in particular were beautiful machines.

[@TheHoveHeretic]

The Hudsons were something special, but my personal favourite was Marc DeCaso's SNCF 242.U.1, thankfully preserved in the Cité du Train museum at Mulhouse.

[@xavierlu5849]

@@TheHoveHereticDo you mean 232U1? There never existed an SNCF locomotive classified 242U1.

[@willsen8908]

My favorite whyte Wheel arrangement is the 4-6-2 "Pacific" type, but thats probably because my favorite locomotive is the SJ F also known as the DSB class E

[@americansteamlegacy-yh9dr]

There were a lot of interesting Pacific's built not just in the US but around the world. Good choice for a favorite!! Thanks for watching!!

[@TB-ModelRR]

Mine too. My first n scale is a BLI Light Pacific UP Greyhound. Beautiful loco.

[@Combes_]

I really like 2-8-2s, big ol' heavy freight engines but still pretty fast. Edit: I also like 4-4-2s, fast and small engines.

[@madalheidis]

The picture you gave for the CBQ's Prairie type is not an American-operated design. While yes, it is a Prairie, and was built in America, by Baldwin, the pictured locomotive is Wellington and Manawatu No. 9, or NZR No. N453, which operated in New Zealand, and is currently the only known surviving engine from the WMR, under restoration in Paekakariki, near to where it originally ran. Also, another story of the origin of the Pacific moniker is again, related to New Zealand railways. The second of the two Q classes in NZR service, the first as-built Pacific, was built in America and shipped across the Pacific to NZ, and the name comes from that journey.

[@americansteamlegacy-yh9dr]

Hi Madalheidis. As for the photo....good catch!!! I was wondering who would be the first to comment on that! I presented how the 4-6-2 became known as the Pacific in the U.S. but it is interesting how it became known by the same name albeit for different reasons in NZ. Thanks for your comment and thanks for watching!!

[@madalheidis]

@@americansteamlegacy-yh9dr The story about the Pacific moniker was not presented "as well as" when I originally read it,, but more in competition to the MoPac story, hence why I brought it up.

[@roelantverhoeven371]

the last "moment de gloire" of an atlantic would be the Belgian Type 12, fastest average speed on a regular rail road track in 1938!

[@americansteamlegacy-yh9dr]

European locomotives are a little outside my area of expertise. What was the top speed? Thanks for the comment!!

[@willsen8908]

​@@americansteamlegacy-yh9dr they had a top service speed of 140 km/h (87 mph) but they had a record speed of 165 km/h (103 mph)

[@cmdrflake]

The name “Baltic” often refers to 4-6-4T engines used in suburban passenger service. The tank engines had limited appeal and ran mostly in suburban Boston and New York.

[@neiloflongbeck5705]

There were several Baltic designs in Europe where the French started this name convention this side of the Atlantic continuing on from the Atlantics. We had both tender and tank engine designs but only one of the former (unless you call it a 4-6-2-2 as the last pair of axles were carried independently).

[@TRAINBUILDER]

Great video!

[@brianwelch-qq3ti]

You missed a couple, such as the 2-4-0, the 2-4-2, the 0-4-2, the 0-6-2, the 0-4-4, the 2-4-4

[@lautanbintangempatlima8350]

I think those arnt really american thing I think he just mention for american loco

[@brianwelch-qq3ti]

@@lautanbintangempatlima8350 they all are. The 0-4-4, was commonly used for Forneys, which were quite common in cities

[@americansteamlegacy-yh9dr]

Hi Brian. I wanted to keep the video to a manageable length, but you're right, those are all worthy of consideration also. Maybe a future video. Thanks for the feedback and thanks for watching!!

[@Sleeper____1472]

What about wheel arrangements commonly used on specific designs? For example mason bogie 2-6-6s or Forney 2-4-4s. There's also the 2-4-0 found on locomotives like the D&RGW Montezuma.

[@americansteamlegacy-yh9dr]

All great suggestions. I'm keeping a list of suggested wheel arrangements for future videos, so I will definitely cover these in the coming months. Thanks!!

[@johnd8892]

Just about every elevated railway started with 0-4-4 T Forney tank locomotives. New York and Chicago certainly. Might have added up to more US people travelling behind an 0-4-4 than many of the other types listed.

[@americansteamlegacy-yh9dr]

That's very possible, John. Thanks for watching!!

[@rivertownproductions]

I’m a bit surprised you didn’t mention the 2-4-0 in between the 0-4-0 and 4-4-0. That’s just me though, I always thought that was a stepping stone between the two wheel arrangement types

[@americansteamlegacy-yh9dr]

Hi Rivertown Productions. I was trying to keep the video to a manageable length and decided to leave the lesser known and more obscure wheel types for a future video. Thanks for watching!!

[@rivertownproductions]

@@americansteamlegacy-yh9dr you’re welcome! And that’s a fair point. I was just wondering.

[@tonyburzio4107]

The 2-4-0 is the precursor of the Mogul 2-6-0, you can see it clearly on how the springing is set up, with the third driver on a rocking arm off the middle driver.

[@connorflaherty175]

I would’ve thought you’d mention sierra number 3 while talking about the 4-6-0 ten-wheelers since she is famous for having a big Hollywood resume.

[@americansteamlegacy-yh9dr]

Hi Connor. That's a great suggestion. Being a Back to the Future fan myself, I'm surprised it didn't occur to me to include number 3!! Perhaps in a future video. Thanks for the comment and thanks for watching!!

[@davidgriffin9412]

What about the 4-6-0 ten wheeler? These were very popular locomotives.

[@americansteamlegacy-yh9dr]

Hi David Griffin. The 10 Wheeler starts at 15:07. There is a lot more to be said about them, but this is just a brief overview. Thanks for watching!!

[@brysonbuckner8104]

I would like to see a cover of a 2-8-8

[@americansteamlegacy-yh9dr]

Hi Bryson Buckner. I don't believe a 2-8-8 was ever built, at least not in the U.S. There was as 2-6-6 called the Suburban which I will cover in a future video. Thanks for the comment!!

[@LocallyUnsmart]

a 4-2-2. yes those exist. this isn’t a joke they existed.

[@steffenrosmus9177]

Yep , an even an 0-3-0 existed where ? On an monorail in Ireland.

[@Elliottblancher]

you forgot about the 4-4-4 arrangement and the 2-6-6

[@americansteamlegacy-yh9dr]

Hi Railfan Canada. Those are definitely candidates for a future video. Thanks for the feedback!!

[@Elliottblancher]

@@americansteamlegacy-yh9dr oh i also forgot the 0-6-6, 2-8-6, and the 2-4-4 which were used on an interesting Locomotive called the Mason Bogie

[@65gtotrips]

Were the little wheels just to keep rail alignment, weight distribution, or both ?

[@americansteamlegacy-yh9dr]

Hi 65gtotrips. The smaller leading and trailing wheels were in part for weight distribution, but the leading wheels were for front end stability. The force of the pistons would cause the front end of the locomotive to "nose" or wobble side to side, the front wheels, or pilot truck, damped the side to side movement. The trailing wheels were to support the weight of the firebox. Thanks for watching!!

[@Pennsy6755m1b]

What about the 4-6-6t

[@americansteamlegacy-yh9dr]

Hi Pennsy 6755. The 4-6-6T will be covered in a future video. Thanks for the suggestion!!
