I have an Atlas Trainman Southern Rwy 52' gondola (#61327) that came with solid-bearing trucks. Is this correct or should the car have roller-bearing trucks? (can't find a photo of this type gondola)
I found a diagram (#62) of this type truck in the Southern Rwy Historical Society archives.
It mentions the use of Barber trucks, but they made both solid and roller bearing. The diagram has a date of 1953, so that could indicate use of the solid-bearing trucks.
