It seems that only North Americans go for this thing about giving wheel arrangements names. The only ones in common use in the UK were Pacific for the 4-6-2, Prairie for the 2-6-2, Atlantic for the 4-4-2 and Baltic for the 4-6-4. I'm sure if they were more, someone will correct me.
Now, as for naming locomotives, that definitely was a trait of the British. At least when they dod that, they did with style. Cast brass nameplates were the norm. While painted names weren't unknown, they weren't common.

i think it can be said that any # + # is called a garret, since the type is a boiler, between two tenders, with drivers under the tenders. i don't know of any particular names given to specific garret wheel araingments.

To be super picky, a few Modified Fairlies were built by the North British Locomotive Co. and they were designated ## + ## , but they were really only an unsuccessful attempt to get around the Beyer-Peacock patent for Garratts. Funnily enough, they were neither Garratts nor Fairlies, but a single frame with pivoting engines at each end. I believe Garratts were "classed" by the wheel arrangement of one of their engines e.g. 4-6-2 + 2-6-4 = Pacific Class Garratt, but as Roger said this was not an important factor in British Steam.

Mikado for a 2-8-2 ie the LNER P1 and P2 classes.
As for names - well,we used to have a wonderful tradition of naming our top express loco's after historic or evocative subjects - my favourites are the King Arthur class named after characters and places from the Legend of King Arthur and the Lord Nelson class named after famous naval commanders. Nowadays they're even namimg 0-6-0 shunters and the names are both random and banal.I'd start a Campaign For Real Locomotive Names if I could think up a catchy acronym :-)

I've heard Southern Pacific employees refer to thier M- class moguls as "Valley Mallets" since a 2-6-0 could haul as much up California's Central Valley as a Cab Forward (also refered to as "Mallets" by SP employees, although they weren't Mallets, but rather simple articulateds) could haul in the mountain districts.
For the term "Valley Mallet", refer to the video "Classic Collector's Series Volume III: The Golden Age of Southern Pacific Steam" by Video Rails. The bit about "Mallets" refering to Cab Forwards is in several Southern Pacific steam books - most notably the Robert Church book "Cab Forward" (now out of print).

I heard that (2'C1')'(1'C2')' is called Pacific-Garratts, (2'C2')'(2'C2')' would then be a Baltic-Garratt and (2'D1')'(1'D2')' a Mountain-Garratt.

Arved,
Yes, it was a common nickname, but no, they could not haul even a fraction as much as an AC or other large engine. They were good steamers and were very effective branchline and local service engines. And on the flat they could haul plenty of freight in that service. They were so cost effective that they weren't replaced until the mid-1950's, long after most of the big engines had been vacated.
Too bad HO scale 2-6-0's can't haul 15 cars! I'd love to use them on locals.

Reading had a number of 2-6-4T sidetank engines used on the Philadelphia-Chestnut Hill commuter trains. All were junked after the commuter network was electrified in 1931. Do these count?

This is the "continental European" wheel notation system. Can you explain how it works? Isn't there also a system in some countries which would describe a Pacific 4-6-2 as a 2-3-1?

Roughly: It counts axles instead of wheels. (most axles have two wheels) Letters are powered axles Axles with an "o" are individually powered. [The discussion above is B-G, steamers, so no "o" Properly Used US diesels would be Bo-Bo or Co-Co.] The punctuation defines articulation at body level, vs at draw bar height, etc. This system was introduced in Europe (Germany?) ca 1890. In the US its used (usually in mutant form) for diesels and electrics, it was developed for all forms of motive power.

Out of interest how would an American describe a diesel loco with two four axle bogies, the outer most axle on each bogie being non-powered - in the UK this would have 1-Co-Co-1 or one with two 3 axle bogies each with the centre axle non-powered - A1A-A1A to us? -- Jon Rose, Apprentice Ale-Trailer, Crawley, West Sussex, England http://members.tripod.com/~jonrose/index.htm

prc> This is the "continental European" wheel notation system.
More exactly it started out at the beginning of this century as the common system of the VDEV, an association of the numerous railways that existed in Germany back then. It found its way into an UIC standard later, so it is one of the internationally used classification systems.
dwp> It counts axles instead of wheels. (most axles have two wheels)
and even wheelsets without axles are counted as an axle ;) (Talgo)
> Letters are powered axles > Axles with an "o" are individually powered. > [The discussion above is B-G, steamers, so no "o" > Properly Used US diesels would be Bo-Bo or Co-Co.]
Rather Bo'Bo' or Co'Co', because, see below..
> The punctuation defines articulation at body level, vs at > draw bar height, etc.
Apostrophe [']: stands after a wheelset, or group of wheelsets, which is not rigidly connected to the frame. (any bogie, or the steering single axles that you will find at steam locomotives, etc)
Brackets [()]: used if driven and non-driven axles are located in the same bogie, e g (Ao1Ao)'(Ao1Ao)' for some diesel locomotives, or (2'C2')'(2'C2')' for a NRZ class 15A :)
Plus [+]: used if a locomotive consists of several carbodies, e g Bo'Bo'+Bo'Bo' for a BLS Ae 8/8.
The articulated bogies between two carbodies are not included in the system.. Bo'Bo'Bo' can mean a locomotive with three bogies and either articulated or rigid carbody. To clear up this confusion, I use a double quote ["] for articulated bogies, but this is a `private standard'. (So an Italian E656 would be B'B"B' , a TGV Sud-Est Bo'Bo'+Bo'2"2"2"2"2"2"2"Bo'+Bo'Bo' .)
> >Isn't there also a system in some countries which would describe a Pacific > >4-6-2 as a 2-3-1?
France used to use this system (without dashes) for classifying its steam locomotives, together with letters that denoted the sub-class. For example, French Pacific classes included the 231 A, 231 B, and so on until 231 K. The locomotive number consisted of this "class" together with a serial number (example: 231 K 22).
> Yup. predecessor to above. Counts axles instead of wheels.
More like used at the same time, but elsewhere.. I never saw it in use outside France. The French railways (SNCF) used a shortened version of the UIC wheel classification system in their numbers of diesel and electric locomotives: CC 6500, BB 15000 ... (the actual locomotive numbers were counted up from there, e g CC 6502). They still use the same system, but now without wheel classification.
(Actually this system is still valid, as French steam locomotives were not renumbered as they were in both Germanies).
0-4-4-4-4-0 or conceivably a B-B-B-B seeing as all wheels are driven from a single power unit.
In neither case would it be a Garrett, which I've always taken to be two power units with the firebox and boiler suspended between them. -- nor could a Fairlie be described as a Garrett, even though these have one or two power bogies. There's also the Mallets and someone else can re-start the argument about compounding on them

I would think it would be classified B-B-B-B:four trucks, two powered axles per truck, both axles in each truck mechanically driven from a common shaft. Does anyone know the wheel arrangement for that monstrous steam turbine-electric passenger locomotive built just after World War Two for the Chesapeake and Ohio?

Looking it up, in North American diesel/electric notation they were 2-C1+2-C1-B.
David Thompson, who wonders how the Europeans would describe Virginian's EL-2Bs...

Over here the first example would be a 1C-C1 assuming that the frame of the locomotive wasn't articulated. As far as I know no locomotive with that arrangement was ever used in North America, although C&O's steam turbine did use trucks of that sort. The second example would be A1A-A1A here as well. These were fairly common, with EMD E units and Alco PAs being the best-known examples.

The second would be A1A-A1A. The first would be 1Co-Co1, the lack of any punctuation between the "1" and the "C" denoting the fact that the single idler and three powered axles were all mounted in a single rigid frame. This sounds like the special locomotives built by ALCO for use in Africa, with an extra unpowered axle added to each truck in order to reduce the axle weight to an acceptable value. I saw some photographs recently of American Do-Do locomotives in service in South America, which I suspect were also built for lowered axle weight.

As no 2-6-4 tender engines were ever built in North America, I find it interesting that Lionel built probably hundreds of thousands of them.
Of course, they also chose to model the Pennsy 6-8-6 turbine and there was only one of those.

SNCF in France also used Diesel engine type A1A A1A. Just a word about an interesting feature of these single-unit engines. The middle axle (non-motive) was mounted on a special device that allows it to slide up or down. When starting to pull heavy trains, the middle axles were moved sligtly upwards, in order to increase the weight of the engine on the 4 motive axles (exceeding temporarily the 20 metric tons/axle limit). When the train has reached a sufficent speed, then the middle axels were slowly moved down to equilibrate the load on the 6 axles around 17 to 18 t/axles.

I found it in a book by Brian Hollingsworth, called "Das Hand- buch der Lokomotiven" in German.. it gives the wheel arrangement of the C&O class M-1 as: 2'(1Co)2'(1Co)Bo' . Translated back from German to English:
The driven axles of the "M-1" were not those that seemed to be when you looked at the locomotive. Three of the four axles of each of the large trucks and the two axles of the rear small truck carried the eight traction motors.
Including the six-axle tender it would be a 2'(1Co)2'(1Co)Bo'+3'3' . I'm not sure how to tell in the Whyte system... :)
