Contest models are expected to not only look nice but to be functional ie be able to run. Hence, couplers and trucks are exempt from scratchbuilding points and couplers and truck treads exempt from conformance. Our models are supposed to be able to do more than sit on a mantel for all to admire.

What a concept! Actually running these rascals on a layout. I donated 3 AP cars to a friend's layout and enjoy seeing them heading from place to place during OP Sessions. They're not baseball cards, run them! Yay, Martin!

AAR code - is an AAR code required on a car? I reviewed a lot of the cars on my layout and most do not have an AAR code stenciled on the side of the car. All my PRR cars do have a code but it is their unique code like X28 or X36 that the PRR used and not an official AAR code.

Joe,
You will sometimes see "XM" which is an AAR designation on some railroads cars, but it's not required to be there. It is required to be on the shipping paperwork for any car used in interchange service.
The X28, X29, etc.. on the Pennsy cars (or the XM24, 27, etc.. on CB&Q cars) is the car class - other than the fact that "X" designates a boxcar in both cases, the car class codes have nothing to do with the AAR at all.

Agree, but that guy is a little creepy.

Orson Welles was a creepy actor playing an arrogant, creepy man during a creepy episode in a creepy film.

Joe,

Getting back to the coupler question . . . Here’s an idea suggested to me: clip the gladhands off a pair of Kadees and use them for AP models and after they’ve been judged, switch them out with unaltered Kadees. Use that same pair multiple times and when you’re done with them, add them to a junk pile on your layout, a enginehouse diorama, or something.

Mike,
Thanks for the input. I've decided to cut the glad hands off and that does make the end of the car look much better. But you broached on another topic I've wondered about as I am about to finish my first car, namely parts reuse. I'm kinda pleased with how my trucks and wheels have turned out and was wondering about reusing them on a later car. At present my plan is to finish 3 cars before asking the judges to drive over from Tampa for evaluation of these three cars plus my Civil Certificate work. So my reuse might be for the 4-th car and beyond. Is parts reuse fairly common when working on the Car Certificate?

Joe, I don't know how common it is, since most of us want to keep our super detailed and scratch built cars intact. However, there is nothing in the rules to prevent it.

Joe,

I asked myself the same question as I was writing my previous response. I would say if you merely attached trucks unpainted, unweathered and unmodified, no problem. If you were to add brake shoes etc to Kadee arch bar trucks, then I would not reuse on another model. I would not myself reuse trucks that were carefully painted and weathered.

While on the subject, we know trucks and couplers are exempt from judging for scratchbuilding, but I read the judging rules under “conformity” to say that wheel sets are exempt but nothing is said about the rest of the truck. Here’s what is written:

EXEMPTIONS: Couplers for cars and locomotives are exempt from conformity judging. No points are to be given for the presence or absence of any style of coupler. Wheels and axles for cars and locomotives are also exempt from conformity judging. No points are to be given for insulated or properly gauged wheelsets or for correct wheel contours.

To take an absurd example, archbar trucks on a 1970’s 50’ boxcar would be problematic. The guidelines tell me that if I’m modeling a prototype I want to install the correct truck design if possible.

Even if I’m wrong, I believe it’s a good idea to develop an eye for details such as the various truck designs. In a way you’ve gone down that road by finding the presence of both Kadee and accurately modeled gladhands to be “weird.”

Going back to your original question, being able to repeatedly do something like painting and weathering trucks successfully is part of mastering a skill.

Hope this helps.

Mike

Almost never done that other than to convert an On3 to standard O....maybe once or twice.

I've finally finished my first AP car except for completing the documentation package. It's taken me about 6 months to complete this car and I'm looking for a means to shorten the construction time for the next 7 cars. Something that crossed my mind was to design using my CAD tool a set of side, center, and cross sills and then send a .DXF file to a friend who has a laser cutter and ask him to cut these pieces out for me. The question that then comes up is whether these piece would/should count as my scratch built pieces.

The last discussion of 3D printing/laser cutting I was present for was in K.C. last year. Summarized, if you do all the design work and prepare the DXF, and all your friend does is load the machine and press the button, I believe it will count as scratchbuilt, points commensurate with the effort that went into the design. But you might not get the Construction/Complexity points a well done assembly of parts would earn.
