Group;

 

To add to Jim:

 

There was a group of these cars I remember well, serving the powdered dolomite trade to USSteel’s mills in the Monongahela River Valley. 

 

They were received by the Union RR of Pittsburgh, in singles, pairs and groups, then routed to the mills by URR. 

 

The open hearths in particular, gobbled enormous amounts of powdered dolomite, for lining the floor of the furnace. 

 

It was dumped on the charging floor, where it was then routed to the pile in front of each furnace for shoveling in.

 

Those cars were in that trade for a long time.

Answers to questions....

 

 

1.  All B&O N-34 wagontop covered hoppers seem to have all been built with wood running boards.

 

2.  No hardware differences between two lots.   There were shop and lettering differences.

 

630300-399 built at Keyser lettered in wartime Kuhler scheme, dome herald on right.  

630400-499 built at Dubois lettered in transition Kuhler scheme, dome herald on left over reporting marks.

 

3.  All my photos, all eras, show wood running boards, even into the 1960's.  No information on metal running boards.   It would not surprise me if there were none.

 

4.  All N-34 had Duryea underframes.   All B&O Duryea underframes were different.  The Duryea designs evolved as each B&O freight car program specified them.   I have little information on these, no knowledge of surviving drawings..

 

 

Your N-34 model with wood running boards is good for 1948.

 

 

Many N-34 were in a pool for steelmaking dolomite (limestone) from the Shendoah Valley line, cars based out of Brunswick, Md.   My 1952 assignment sheet puts 53 of 200 N-34 in this pool alone.   This quality dolomite was sought after by eastern steel mills some distance away, so N-34 got around the rust belt before it rusted, and were interchanged with other railroads.

 

 

Atttached is a lettering scorecard for offset side twin hoppers, valid for the N-34 schemes.

I have four questions about the B&O class N-34 wagon top covered hoppers:

#1  -  When the 200 cars in class N-34 were new in 1940, did they all have wood roofwalks?

#2  -  What was the difference in construction or features, if any, between cars numbered 630300-630399 and 630400-630499?

#3  -  When did the N-34 class start receiving Apex roofwalks?

#4  -  Did all of these cars have Duryea underframes?  If so, is there a diagram for the particular type of Duryea underframe that might have been under these cars?

The reason for these questions is that I am trying to decide whether to keep my O Scale I&I Models N-34 with wood roofwalks - is it appropriate for the time frame of April, 1948, or had all of the prototype cars been fitted with metal roofwalks by then? (I&I imported the same brass model with Apex roofwalks.)
I have not been able to find any information or freight car diagrams for these cars.

Thank you very much for your help!

 

Does anyone use a true database program to keep track of freight car models? As opposed to a spreadsheet program.

Thanks,
Bill

Is there a listing of on line shippers for GN?

    Gary, I can't answer your question about the produce bags, but what I have found to be very dependable over years of use is ordinary sandwich bags (the kind where you tuck in the flap to close). These protect a model from abrasion on protruding parts like grab irons, and do not seem to interact with the model surface. 

When REBOXX was selling boxes, they had researched “the best” plastic wrappers for models, in part because one of the workers had had very unfortunate experienced with wrapping models he’d custom painted and his customers finding . . . problems.  Unfortunately, none of the surviving personnel remember what it was.

Gary, with my moving, packing HO rolling stock has been a concern. Damage was occurring until I began using these products.

To protect each car I do use pieces of this foam, with additional pieces to line the boxes https://www.uline.com/Product/Detail/S-787P/Foam/Foam-Roll-Perforated-1-16-24-x-1250

I use these boxes https://www.uline.com/Product/Detail/S-3189/Indestructo-and-Literature-Mailers/23-x-13-x-2-1-2-White-Literature-Mailers

The boxes are perfect for rows of HO cars or engines.

In 1955, GN changed the slope sheet angle on some of their 73000-73199 hopper cars:

from about 30 degrees to 55 degrees, and renumbered them into the 73700-73764 series.  The cubic capacity dropped from 1622 to 1253.

I've asked after this matter on the GN group.  Nobody knows why.

So I'll bring the subject up here.  

What load would GN have modified these cars for?

I'm interested in factual knowledge, and also informed speculation, since I have doubts anyone knows specifics on this matter.

My suspicion is that it was for "ore", or what most civilians would call "dirt".

I will also speculate that if the "ore" were no longer being transported, they'd be prized as hopper cars that would dump just about anything.
