    Those are ASF Ride Control trucks. They appear to be 1970's vintage with 7 x 12 bearings and 38" wheels.

    Look at the friction castings and the bolster slope pockets - ASF Ride Control.

    The friction wedges and corresponding spring holders in the bolster simply denote it's a ride control truck, which any style of truck can have, regardless of if it was made by ASF.

    I'll have to dig out and compare the ASF Barber S2-HD Ride Control drawings to the ASF Ride Control drawings...

    The trucks for CEBX 8000 were cast in 1981 or so.

    Only Ride Control trucks have Ride Control friction castings. Other styles of trucks use other methods of truck stabilization.

    Don't confuse the design of the truck with the manufacturer of the side frames and bolsters. The Ride Control and the Barber S2-HD are very different. The Barber S2 was a competing design of ASF's Ride Control. A National C-1 or a Buckeye XCR or an ASF Motion Control are truck designs. The actual manufacturer may be one of a number of foundaries that have come and gone over the years.

    The photo above is not sufficient for me to determine the manufacturer or the casting date, but it is clear enough to identify the truck design as an ASF Ride Control - as opposed to an ASF Ride Master or a Barber S2, etc...

    Not true... there are Barber ride controls... just like there is no patent on the Barber design features internal to the sideframe and spring pockets, there is no patent on ride control features... any manufacturer can make a truck that utilizes sprung friction wedges against pads, not just ASF. I am well aware of the differences between sideframe design and manufacturer... that's why I specifically pointed out that I wanted to compare the drawings of ASF's own ride control truck vs the Barber S2-HD (which differs from the S2 and S2-C) ride control offered by ASF...

    To me it looks like a 100-TON BARBER S-2 TRUCK

    I think you may be confusing the two truck designs. The Barber S2-HD is a specific truck design, and it has been produced by many different manufacturers, including ASF. It is totally separate from and has nothing to do with the Ride Controltruck design also produced by ASF. The ASF Ride Control utilizes a different method of stabilization from that of the ASF Barber S2-HD. Only Ride Control trucks contain Ride Control friction castings. Barber S2-HD trucks utilize either Barber friction castings or a version of the Pennsy split wedge. You will not find drawings of a Barber S2-HD Ride Control truck - it does not exist.

    All of the Ride Control designs are based on bolsters with internally sprung friction castings that create a constant force against the column wear plates regardless of the amount of weight on the bolster. In contrast, the Barber designs utilize springs that sit in the spring nest under the friction castings to create a variable force against the column wear plates that increases as the weight on the bolster increases. Ride Controls and Barbers are two totally different animals.
