Alex, you asked, I answer:

This is a Pere Marquette company diagram, has all the important dimensional info on it. Hopefully this'll be of some use!

Here are some other pictures...

More photos...

Missouri-Illinois 6250-6349
MI 6273.jpg


Milwaukee Road 370001-370500
MILW 370233.jpg


Rock Island 88900-89399
RI 89326.jpg


Texas & New Orleans 4200-4449
T&NO 4252.jpg


That's what I found at a quick look-through... give me a bit to see if there are other matches!

As it stands, even with the above the regional distribution of these cars is fairly wide: PM in Michigan; Bangor & Aroostook, Bessemer, C&O and Erie in the northeast; Missouri-Illinois in the midwest; Milwaukee Road in the Northwest (Illinois to Washington); Rock Island in the midwest, south and southwest; Texas & New Orleans in Texas and Louisiana. So just with these cars, if you model just about any region in the continental US, you can use some of these cars! :)

Am I missing something or isn't that a 3 bay? Or do the 4 bays use 3 chutes?

It is a triple indeed.

I'd mentioned TT needing triples and quads, thought you were referring to both with your offer.

Something which might sweeten my proposal, though: just finished looking through my stuff. I found 7 bang-on photographic matches: New York Central (huge!!), Boston & Albany, Delray Connecting, Delaware Lackawanna & Western, Canadian National, Canadian Pacific, Kansas City Southern - that's three major roads; this design truly is/was continent-spanning! As such could definitely be of interest to many people, I think...

Additionally, I found one photo of a very similar car of the Pacific Great Eastern (later BC Rail), but it has only 10 panel instead of 11 as on the above cars.

No photos, but found many possible matches in data/info... 13 I'd rate as very probable (including some major roads, Southern, CN, CP, Missouri Pacific), and 12 possibles (including Illinois Central & Chicago & North Western).

I have to go to work now, but will post the new photos and findings after I get home! :)

(Does my excitement over this show too much??)

Oh, d'oh!! Just realised I'd titled the thread "4-bay"... I'm a dinlow! :(

I could do both I guess - not TOO much difference between them I suppose. I'll change the thread title.

That's an idea, too... after I get a few things out of the way (getting the promised info/photos into this thread in a few, and something new for the freight car thread), I'll start a dig through my stuff to find out what the most widely-used quad hopper was. I think (I may have mentioned this before... :P ) that the first things that get done in TT are the things that were the most widely used...

So, this took a little longer than anticipated - but the positive thing about the delay is this: I now have combined the two separate collections of photos (one on my desktop, one on my laptop) into a single big collection. So photo hunting will now be a lot easier...

Anyways, as promised, here are the other things I've found that match this type of car.

Matches with photos

New York Central 903500-903999, 904000-904999
NYC 904633.jpg


Boston & Albany 25000-25499
B&A 25144.jpg


Delray Connecting 5001-5100
DC 5050.jpg

Matches with photos, cont.

Canadian National 109100-109104
CN 109100.jpg


Canadian Pacific 359000-359999
CP 359385.jpg


Delaware, Lackawanna & Western 84082-84949
DL&W 84024.jpg


Kansas City Southern 29200-29349
KCS 29237.jpg


Similar, but only 10 panels instead of 11
If you can live with the difference, close enough - but so far, this is the only offset-side triple hopper I've seen of this exact design...

Pacific Great Eastern 261-280
PGE 273.jpg


No photos, but probable matches
I call these probable because they match the dimension/capacity info I have exactly to cars I've listed with photos (which isn't a guarantee, but it's a good indicator).

Canadian National 108600-109099, 109105-109954, 119000-119499

Canadian Pacific 360000-360724

Chicago, Indianapolis & Louisville "Monon" 4501-4601

Detroit, Toledo & Ironton 1600-1649

Louisiana & Arkansas 4400-4799

Minneapolis & St Louis 66001-66499 (odd numbers only)

Missouri-Illinois 6350-6449

Missouri Pacific 61000-61999, 62000-62759

Nickel Plate Road 78000-80999

Ontario Northland 140300-130324

Pittsburgh & Lake Erie 3000-3099

Southern 70000-70299

Wheeling & Lake Erie 78000-80999

No photo, but possible matches
These are triple hoppers whose dimensional info is similar to cars I have photos of, but not exactly identical.

Baltimore & Ohio 621000-624999

Carbon County Ry 7300-7349

Central of Georgia 700-899

Chicago & Illinois Midland 1000-1098, 11000-11049

Chicago & Illinois Western 900-934

Chicago & North Western 65101-68103 (odd numbers only)

Chicago Great Western 69000-69099

Chicago, St Paul, Minneapolis & Omaha 49701-49999 (odd numbers only)

Illinois Central 81500-81744

Lehigh Valley 41000-41699

Minnesota Western 100-129

Roberval-Saguenay 932-961

So that's what I've got. Even if only a few of the probables/possibles do match, I think there is a huge variety of possibilities what someone could do with a model of this design...

At the weekend at some point I'll post some more photos, I should have some shots of the inside, certainly of the ends...

Here's a test drawing of the AAR 70T 3-bay hopper to visualize the concept. A one-piece cast body may not work because the interior sides are bowed out creating the "offset" feature of these hoppers. Although, if the cars are to be loaded it wouldn't matter. Running emties would require either a complex mold or a series of flat castings assembled into the finished car.
