Was looking to purchase a few from RLD Hobbies.

I noticed that there are the archbar, and TWO more modern trucks.

I'm familiar with the Bettendorf trucks, of course, but any ideas or comments on the use of the A-3 ride control trucks? They are 50 ton like the Bettendorf.

I cannot see a lot of difference in the model, although apparently this is an improved design over the Bettendorf's in the real world.

Greg,
While at the NMRA convention show in Portland about three weeks ago when I was looking at one of the Bettendorf trucks I was told by a guy at their booth that there will be rollerbearing trucks soon. Thats all I know about it. Maybe an e-mail to Kadee might clarify when.

Robby's site has pictures of the archbar and these other 2 that are so similar.

I cannot really see the difference.

Greg,
Those two Bettendorfs look the same to me. I hope the Kadee rollerbearing trucks have a decent price point. Have you seen what they are getting on Ebay for the aristo-Craft 29100 rollerbearing trucks? Hard to believe that people will cough up so much for them. Supply and demand I guess.

Yes, it is horrific! I have not looked at the prices for USAT roller bearing ones, have you used them very often?

The only USA rollerbearing with rotating caps that I have are the ones that came on the modern cars like the tankers and 60' boxcars. All that I purchased in the past were Aristo. All my 50' cars have rollerbearing. Glad I did it when I did. I can remember getting them for around $21.00 per pair.

Theres is a common and prevalent problem in advertising in our life.

... one picture is worth a thousand words ...

... yet may not be the exact item being offered for sale...

Need to hold 'em in your Hot little hands to see differences!!

From Freight Cars of the '40s and '50s

"Introduced around 1940, the A-3 Ride Control truck from American Steel Foundries (ASF) didn't have a spring plank. The springs instead rested on a pedestal cast integral to the truck sideframe. This truck became the most popular solid-bearing truck into the 1960s."

"On early trucks, the springs rested on the spring plank, a C-shaped channel that ran between the sideframes. Modern trucks eliminated the spring plank (thus the term plankless is used to describe many trucks), and instead have the springs rest on a platform cast into each sideframe."
