In the Atlas email I just received, I noticed they were offering/promising several types of three rail trucks, including
friction and roller bearing caboose trucks (no pictures of these, so I wondered what was the difference). Apparently
three common types such as Bettendorf are already available. Unfortunately, there was no mention of any archbar
ones to become available. I recently picked up some Weaver Lionel-compatible couplers, and I assume Weaver is still offering their two types of trucks? I am guessing the caboose builder on here will be interested in those caboose trucks,
as will I.
