Barber Stabilized S-4-L Trucks

Steve and Barb Hile

The Rock Island used this unusual truck under the 10 aluminum express
boxcars built in 1945, 20060-20069. They are essentially like the Bethlehem
Kit Bits number 1213 including the Timken Roller Bearings. It also looks
like the Barber S-5-L shown in Richard H's MRH truck article in figure 56,
except with Timken Roller Bearings instead of the solid bearings shown

What I am curious about is whether anyone can point out other roads using
this truck?

Thanks in advance.
