@thomasjmdavis , can you provide any clear hi-res images of the truck on a car?

@Lemosteam - sent you a PM.  Let me know if any of those would be helpful.

The only thing missing from the drawing is the vertical ‘thingy’ (?) in the center in front of the spring.

Dampner, snubber (a shock  absorber, similar to what automobiles use)?

Usually a snubber limits motion to a certain parameter like preventing truck hunting, A dampner stops a motion when it starts like harmonic rock

From the photo of the truck in Randall's Pullman Standard Vol 1, I am guessing it is a shock absorber.

Here is a Coach Yard version of the car in HO- if you scroll through the pics, you will find a couple that show the truck detail.

I do note in John's drawing that he includes the mounting holes for the bracket the holds the (presumed) shock absorber.

Here is the final design for the ATSF Express truck.  They will use any 0.504" x 36" wheelset and an Micro-Trains bolster pin. 





Per the client,  the brake apparatus will not be available as the details are too small and delicate to print properly., but I might be able to convince him of an upgrade kit with pseudo brake discs for behind the wheels and a the proportioning valve- but a modeler would be on their own for brake lines and hoses.

The client will upload the design to his shop at a later date and likely would announce it here on TRW.

Them Photobucket bands across the middle of every picture do tend to ruin your images.

Since this thread was started (7 years ago?), I’ve built 4 more of these 64’ ATSF semi-lightweight smoothside baggage cars using Bills superb castings, as soon as they were available.
 I chose to paint 2 in the gray scheme and 2 in the silver scheme.
Of course they still don’t have proper trucks. The Micro-Trains BX express trucks that I had originally used on the AMB laserkit build have been replaced by modified Kato passenger trucks, which, although incorrect, were closer in size to the correct trucks (still too big).
 It will be nice to have correct trucks under these if they’re ever made available.

Those look great Bruce.  I have one I did years ago from the AMB laser sides, but have never been happy with it as I made my own "core" out of the scrap box and had a glue "leak" after it was painted and one of the doors popped off.  So a couple of Bill's kits are on my list for after I reduce the backlog of unassembled kits and sides below 50. 

Are the grabs and steps on yours from Gold Medal or BLMA, or did you need to fabricate to get the right sizes?

And while I am asking questions.... what paint did you use on the 2 cars in the photos?  Looks spot on compared to photos.

I don’t quite recall for the gray,( a few years have passed) but I’m almost sure it was dark lark gray.
I do remember the silver was Floquil bright silver followed by Pollyscale clear flat to give it the correct ‘finish’

Here's my version using one of Bill's castings.  I used Con-cor trucks.

The silver is Krylon rattle can dull Aluminum.
