dti406 In the early sixties there was a change in the rating of the bearings and springs in the trucks and they were now rated for 77 Tons or 154,000 lbs. using 33" wheels.

Ah ha! Didn't know that and I can use that for future reference.

Rule 1: This is my railroad.
Rule 2: I make the rules.
Rule 3: Illuminating discussion of prototype history, equipment and operating practices is always welcome, but in the event of visitor-perceived anacronisms, detail descrepancies or operating errors, consult RULE 1!

On page 31 it contains a table showing all AAR certified wheels with their load limits.Regards, Volker

I don't know if this helps or not but a good picture of the prototype for the era I model is located at this link: http://www.rrpicturearchives.net/showPicture.aspx?id=2472268.
What is the prototype?
Generally I have searched the Internet for prototype specs.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
I am in need of help from my forums friends again. As I have been unable to find an in production model for my prototype, I am planning to remove the existing lettering on a amother car from that company and reletter it for my prototype. However the model has the wrong type of trucks. (Solid bearing on the model and my prototype uses roller bearings.) As the prototype is a 75 ton car, I am having a question as to the correct size of the wheels. IIRC 33" wheels have a 70 ton limit. Therefore, am I correct in thinking that the car would properly ridden on 36" wheels which have a 100 ton limit? As usual, thank you for any assistance my forum friends can provide.
