I don't think that the line on the side of UP 4017 is exactly a class designation since UP did have an alphanumeric class designation for its steam locomotives. It looks more like some basic specs of wheel arrangement and cylinder dimensions. I believe that Southern had something similar on the sides of its locomotive cabs.

My unprofessional diagnosis is that this class designation was dreamed up by some seriously OCD engineers.
And isn't the U.P. on this cab a bit unnecessary?

The thing to remember about any system of identification - "It made sense to the people that originated it at the time they originated it". Times change and what made sense 50 years ago, may not make sense today. What makes sense today most likely won't make sense a generation or two into the future.
Never too old to have a happy childhood!
cefinkjr ATSF seems to have always used locomotive numbers for steam locomotive types. Did they even have an alphanumeric class system?

ATSF used the number of the lead locomotive of that design as the class type, such as 3829, 5000, 5001 and 5011 as classes of 2-10-4's. This system continued well into the diesel era, which must have been quite confusing with various classed of F3's and F7's.
tree68 With Diesels, it appears the Central wasn't too worried about using engine numbers for classes - The first RS3 (DRSP-6A) was 8223 - probably the next number after the last RS-2. They might have done better with other models.

Not being a big fan of Diesels, I really can't say much about them. I do remember very clearly though that GP-40s, the hottest power on "The Water Level Route" at the time, were all numbered in the 3000s.
cefinkjrAlthough alphanumeric classes were defined, NYC people hardly ever used them; Niagaras, for example, were 6000s -- not Class S-1a, S-1b, or S-2a or even Class S.

tree68The Whyte system and individual railroad names for types of locomotives notwithstanding, many roads also had "alpha-numeric" designators for their steam locomotives.

I think most roads had an alphanumeric class system for steam locomotives and, later of course, Diesels. This was another of many differences between NYC and PRR that I noticed when I hired out on the Central a few months before the PC merger.
Although alphanumeric classes were defined, NYC people hardly ever used them; Niagaras, for example, were 6000s -- not Class S-1a, S-1b, or S-2a or even Class S. PRR people always used classes (e.g., K4) or names (e.g., Pacific) and never locomotive numbers to indicate a group of locomotives. Of course, PRR numbering was so chaotic, using numbers would never have worked.

You're misremembering how complicated it was.
It was never as simple as Pentium 2 or Pentium 3. There were 14 different Pentium II processors! Then individual chipsets had their subvariants, like the five different kinds of i810. Celeron, P II, and P III were all subsets of the same family and those names were mainly marketing devices. The rat's nest of Intel chipset names, families, and heritages makes the simple EMD and GE naming schemes downright elegant.
Back in the day when I was a late teen chasing trains in the mid 70's, GE classification was so simple back then "U-boat on the point!" By the sound and the smoke, it sure sounded like a Pocono and we wanted to be clear among us what was a-coming (yes chasing the EL through PA down through NJ was fun!)
Very true.
NorthWest Regarding the complaint by the OP, I think that steam locomotives are actually easier, following a common (Whyte) classification, unlike diesels, which has a different naming convention for each builder.

I wouldn't go too far in extoling the simplicity of the Whyte system. An ATSF 4-8-4 was quite a different locomotive from a TP&W 4-8-4, CV 2-10-4's could not perform like PRR 2-10-4's, few 0-8-0's came close to an IHB U-4a 0-8-0, etc. On the other hand, NKP 2-8-4's from Alco and Lima were almost identical.
Firelock76And then there's "Diesel" from the "Thomas the Tank Engine" stories, who introduces himself simply as "Diesel". "Hell-o, my name is Diesel", he said with an oily voice... And vsmith, I saw three of those "thingy-wingys" here in Richmond VA today. The second "thingy-wingy" you've got pictured. Those "Great Pumpkins" were a nice change from the CSX "thingy-wingys" I usually see.

(Yes, it should be *have* not *has* in the last post, I made it more concise and failed to proofread.)
Balt, that is true, but you won't find the exact model. This is true with steam, as well, but I think an uneducated observer would have an easier time telling a 4-8-4 from a 2-8-4 than a modern C-C from an A1A-A1A.
Anybody got a link to dale's (nanimo73) breakdown from a few years back? it covered this quite well.
With the same specificity that applied to the Whyte system of classification for steam engines, todays diesels are ever easier - A1A - A1A; B - B; C - C
Heritage I Dash 9-44CWs aren't a rarity here, but are nice to see.
vsmith, do you mean an SD70ACe? My understanding is that BNSF SD70MACs are rare in the LA basin, mostly sticking to coal trains. UP has a lot of the SD70Ms, though.
chutton01 BoydGE C44W-OU812Well, what did you expect when you use locomotive designations developed by "Van Hagar" it used to be simpler like SD40-2 (my favorite)So you did NOT like the SD40 locomotive then? You do realize that the "-2" designator was applied by EMD to existing models to indicate they had upgraded internal components. Marketing ploy, more or less.
BoydGE C44W-OU812
it used to be simpler like SD40-2 (my favorite)
There's some truth to that but, a Dash 2 locomotive has a vastly different electrical system than non Dash 2 units and if EMD had not applied a suffix to the model number many railroads probably would have on their own due to the differences in maintenance procedures and parts ordering....
"I Often Dream of Trains"-From the Album of the Same Name by Robyn Hitchcock
I don't know if it's that complicated...an SD-70 is just the grandson of the SD-7. Sometimes the designation will include AC or DC to tell what type of power the traction motors use.
For many GE models, the first letter tells you if it uses two-axle (B) or three-axle (C) trucks. Then there's two numbers, the first two numbers of the engine's horsepower. Then a "dash" designation telling you what generation electronics it's using. A B-30-7 would have two two axle trucks, have 3000 hp., and use 'dash 7' generation electronics.
Starting in the 90's a W designated a 'wide' cab rather than the older narrow cab/nose typical of low nose diesels. So a C-44-9W is a "dash 9" generation GE engine with two six-axle trucks, 4400 hp, and a wide or 'comfort' cab.
As for the Whyte system for Steam Locomotive designators... Americans count wheels, Europeans count axles... thus a 2-8-4 is the same as a 142. But how do you list one that has an idler axle between drivers on the same set of cylinders?... I have seen it listed as a 2-2-2-2-4, the first 2, the 3rd 2, and the 4 are the unpowered trucks and the 2nd and 4th numbers are connected by side rods driven from forward mounted cylinders, but you cannot tell from the "Whyte" nomenclature. The Whyte nomenclature also does not give any information as to size, shape, power, or capabilities (or does it have a booster built-in to the trailing truck... what about a booster in the tender truck?.
You can only guess that no leading truck is probably a switch engine, a 2 wheel leading truck is probably a slow freight engine and a 4 wheel leading truck is probably a fast passenger engine. But depending on the age of the loco, it might have been built for nearly any purpose or it might have been pressed into a service it was not designed to do, because the RR was short of the appropriate power, or found out that it worked well in the other service, or was repurposed to some other service because it was still usable, but not needed for the service it was purchased to do.
Semper Vaporo
Pkgs.
Well, I SUPPOSE all those complicated designators make sense if you understand them. Certainly they make sense to the people who come up with them.
Personally, they make no sense to me at all. So I look at it this way...
There's big diesels, bigger diesels, bigger-bigger diesels, dirty diesels (common), clean diesels (less common), smelly diesels (VERY common), ugly diesels (all too common).
Oh well, better than no trains to watch at all.

The Pennsy K4s (and its predecessor K-2, K-2a, K-2b and K-3) was a Pacific. So was the CP "G" class, and the Southern Ps4.
The railroads did a similar thing with Diesels. NYC called the RS3 a DRSP-6a (when configured for passenger service).
The designations can really tell you something once you decipher what they are saying. ALCO's Century series locomotives contained the series, horsepower, and number of axles (C-424 - Century, 4 axles, 2400HP).
The "F" in the F3, F7, and F9 originated with the horsepower as well (fifteen hundred). The "E" in the E units meant eighteen hundred (two 900HP prime movers). Of course the HP changed later, but the letter was set by then.
As has been noted, at one time, you could pretty much tell one locomotive from another - there were distinctive "spotting features," although some could be pretty arcane. Where was the sight glass again? \
I liken that to the day when you could tell what make of automobile you saw driving down the road. There might be some minor differences between "sub" models of a certain make, but there was no mistaking a Ford for a Chevy for a Chrysler.
You younguns oughta appreciate improvement. In my day "...out west...commuter trains" meant San Francisco Peninsula service. You now have San Diego, Los Angeles, San Jose-Sacramento, Altamont Commuter Express, Albuquerque-Santa Fe, Salt Lake City, Portland, Seattle, Dallas.

Painted in either orange or yellow or occasionally black, because thats ALL I ever see out here.
Its quite a sad thing for railfanning when the commuter trains offer a wider variety of motive power.
