Hi,

 

I recently purchased one of Jon Cagle's ATSF Bx-12 Extended Height Boxcars and am looking for guidance on the correct trucks for this car for the 1950s.

 

According to an article written by Richard Hendrickson (who I know is a well-known Santa Fe expert who sadly recently passed away) in the May 1995 Railmodel Journal, when originally built Bx-11s received Dalman two-level trucks and Bx-12s and -13s received Dalman one-level trucks.  This makes sense because Dalman two-level trucks were manufactured before one-level trucks.  The article goes on to point out that during post war service sometimes the original trucks were replaced with more modern types.

 

What I find confusing is that in the nine photos I have of prototype cars, all seem to have Dalman two-level trucks.  I am still developing an eye for identifying trucks but as best I can tell they are Dalman two-level as opposed to other types including ASF A-3 ride control trucks.  They are certainly not Dalman one-level trucks which have a more distinctive look.  I realize 9 cars is no where near representative of 4,000+ cars but since all seem to have the same trucks, I am left to wonder whether or not most, if not all, Dalman one-level trucks were replaced by some point in time in the late 40s or early 50s.

 

I know Dalman one-tevel trucks are readily available in O scale but so are others that may be more prototypical correct for this car for the 1950s.

 

So would greatly appreciate any guidance and if you could cite the information source all the better.

 

Thanks, Bob

OK...with a little more digging I think I answered my question.

 

In another article by Mr. Hendrickson in Model Railroad Hobbyist in May 2013, he provides excellent photos of both the two-level and one-level Dalman trucks which almost look identical except for very small steps for the outside springs on the the two-level trucks; hence the term "two-level"; whereas the springs for the one-level trucks are all on the same level.  This suggests that my photos do in deed show Bx-12s with Dalman one-level trucks.

 

What threw me off is that o scale trucks for sale on ebay are tauted as Dalman one-level trucks but unless this particular product represents some type of clone or variation of this truck, it appears to me to differ in a lot of ways from a true Dalman one-level truck.

 

Any thoughts as to why these o scale trucks are being advertised as Dalman one-level trucks but to me have little to no resemblance to the prototype?

  Because it's an obscure 60 year old product so the seller probably went with what he found written on a box which might not be the correct box or might have been mis- labeled originally? Lots of old O scale trucks were manufactured by various companies over the years, some pretty nice and some pretty crude, I  had dozens of variations on my O scale cars and didn't know what 75% of them were correctly called :> I'd just go by the photo that best matches the number series of your model and use the trucks that best match it....DaveB

These particular O scale trucks are a new production but know what you mean about sellers not knowing what they are selling.  Sometimes that's to the buyers advantage.

 

Reading the product description for these particular O scale trucks more closely, the seller does cite reference material about these trucks but I checked various old articles on freight car trucks in pubs such as Railway Prototype Cyclopedia, etc. and haven't seen a Bettendorf-Dalman 70 Ton truck presented.  Even if I don't use these trucks, now I am curious to know more about them.

 

I did note that some others who have built the ATSF Bx-12 kits installed these same trucks (Bettendorf-Dalman 70 Ton) but now I am wondering if they made a mistake and didn't realize it.

 

If a true Dalman one-level truck is not available, I will default to a 1950s 50 Ton truck like the ASF A-3 ride control and call it good.  I did touch base with Protocraft and they are considering doing the Dalman one-level truck sometime in the future but nothing more definite than that.

      Ok, I found the ebay link and now I understand the question.  Apparently Dalman made their own Dalman type trucks as well as bettendorf and other types so these ebay trucks are not Dalman type but are Dalman manufactured bettendorfs. If you need two level Dalmans for that boxcar you could get some older O production trucks, can't recall if they were Keil line or Lobaugh or who but they are much cruder than those brass trucks. I'll look thru my O stuf and see if I have any left.....DaveB

I would suggest that you join the Yahoo P:48 group.  The list owner Gene posts on here occasionally but that list is probably a better place to discuss since there are quite a number of west coast O scalers on there and they likely have the same car... AND accuracy and prototype fidelity is of primary importance to most of us on there.  

 

I don't recall actually seeing either single level or two level Dalman trucks in brass.   The ones you have found labeled so on Ebay appear to be from one of the George Kohs projects that the builder absconded with. (Please fellas, no need to turn this into a love/hate Kohs discussion).

Gentlemen,

 

Thanks for taking the time to provide guidance...all very helpful and appreciated.

 

I will broach the question to the Yahoo P-48 Group as recommended.

 

The Bx-12s had "one-level" trucks which means all the springs were on the same level.

 

I did see another recent post on Dalman trucks and the old O scale versions are too crude for my interests.

 

As many others have probably also observed, prototype photos of cars uusally are at such a distance and/or lighting is such that the image of the trucks is to small or they are in the shadows and therefore unrecognizable as to type.  I did blow up one prototype photo and did manage to get a much better image of the trucks under at least for one Bx-12.  So making progress chasing this down.
