What you illustrate is called a “binder-head” screw. They have the thinnest head among the common screw types. Due to the shallow head few have Phillips or cross-head driving recesses. They were developed to hold wires to terminals, called “binding”. They are commonly found in the electronics industry, especially on barrier-type terminal strips.

Charlie Vlk posted this reply to the Early Rail discussion list on this Bachmann model.

 

As I said, the car body is the standard Bachmann 40 Ft steel box car.  I wouldn’t be surprised if it is the same mold or started life as the Athearn copy that Kader made for Mantua as their “Crown” line in the 1960s that were sold as carded RTR cars.

The printing almost makes a convincing car though….in the catalog.

IMO, this model might prevent another manufacture from producing a model with prototype fidelity. Other than the screening, there is little about the Bachmann model that reflects the prototype poultry cars.

 

Oh, it has wheels. I forgot the prototype poultry cars ran on wheels.

Well, I agree that it’s not tight to the floor above it, but . . . it’s also appearing to be bent, and on a wrecked car, I’d be cautious about generalizing from the condition of this particular diagonal to say that all diagonals on PFE reefers are the same.  Once bent, that channel has lost a good bit of its integrity.

All the way at the left edge of the second photo https://dl.library.ucla.edu/islandora/object/edu.ucla.library.specialCollections.losAngelesDailyNews%3A1053
is another car that shows both diagonals and neither is bent. I'd say the cars were built this way. the 1910 era NYC 36' steel underframe boxcar I tooled a couple years ago also had the diagonals below the floor stringers; they are on the Pullman builder's drawings. Those diagonals run the more conventional way, from the center of the bolster out to the car corners, likely to reinforce the frame behind the poling pocket. I'd say the purpose of running the diagonal in the opposit direction is to keep the body bolster from bending when the roping staple was used to move too many coupled cars.

I keep running into a difficulty of the draft gear box wanting to rotate if the screw isn’t really TIGHT, which can be obviated by making sure there is a continuous contact between the back end of the box and the center sill, or, of course, by some adhesive.  I really prefer the very flat headed screws I mentioned before as it reduces the side profile of the screw head.  They look something like this:

But have an even flatter head

When I got the dozens I have, they were only available with the slotted head.  I see now that there are some which are cross-headed screws.

Hi List Members,

 

It is exactly for this reason that I prefer brass screws - they are relatively easy to cut to a custom length (much easier than steel screws), but since they are metal they are stronger than plastic screws

I use the Kadee screws for cases (hoppers and flats) where the length of the screw causes it to emerge
and become visible - or if it interferes with something inside the car, like a weight. I install it, and then cut it
off flush. If you're snapping them, you're over tightening them. Use a tiny drop of Loctite if you're worried
about them coming out.

Slot or Phillips is irrelevant - why use plastic screws if electrical shorts are not an issue?  Use metal screws instead.

When I was building the Yarmouth kits for the earlier 14000-14299 series cars (which had the proprietary ACF ends and 7-foot doors) I also built one of the 8-foot door cars (14300-14599) cars using a Branchline kit as the starting point.  The sill tabs were removed and a solid bolster-to-bolster sill was fabricated from Evergreen styrene.  Also the gusset plates were added next to the door.

The photo Tim posted clearly shows the extra vertical row of rivets in the side panels.  I used Archer Transfers rivets for these.  A photo of the completed model is attached.  I used a Yarmouth etched running board and Tahoe Barber S2 trucks.  I used the Mask Island decal set for the compass herald paint scheme with a repaint date of 1959 keeping it eligible for this list.

Group;

 

I have searched in vain for my copy of the MM issue in which Bob Hundman outlined the NKP all-steel 50-foot double door box cars, in two series, one of which had Viking roofs.

 

Does anyone on the list know much about these cars?  Were they built for automobile or auto parts service?  I know NKP had plants on-line.

 

They look unique in several ways.  Did some have racks?  Were some or all originally “Damage Free” cars, or did that come later?

 

Do you know anything about the cars that went to P&WV?  They appear to have stenciling that would indicate as assignment.  Any idea to whom?  See attached.

 

Thanks in advance!
