What is the difference between GR plan set #17 and #56?

I guess you're right about the scale. Do you think this plan takes a lot of skill to build?

I noticed that Gary Raymond makes 1:20.5 scale 18" wheels. They say: "For small ore and log cars."  Would they be a good choice of wheels for this car?

 For an industrial ore car, I'm not sure the difference between 1:22.5 and 1:20.3 is going to be anything to worry about.

Also, I see that #56 is in 1:20.3 scale, but #17 just says "G scale", so is it scale specific, or is it in 1:22.5, or what?

[IRB Souther Engineer]

So #17 is probably the better one.

Plan # 56 is a non-working version of plan #17 looking the pictures

What do you mean it is a non-working version?

Look between the hweels, do you see the dump hatch in the bootom?  That one will dump the load, the other will not self dump.

It looks to me #56 is an updated version of #17. Good Luck - Peter

What is the difference between GR plan set #17 and #56? They look the same. They are both ore car plans. I am thinking if I maybe (someday) I'd make one of them but am confused because they seem the same.
