I can that the R-40-2/4
series appears to have different trucks from the R-30-12/13 series
T-section trucks. Is it just the trucks?

Bruce, the 40 ton built-up underframe was essentially of the same
design as the 30 ton built up underframe, but slightly larger and
heavier. The difference is small enough to be negligible in HO
scale, so IMHO the Tichy underframe is acceptable to model both
(unless, of course, you're obsessive-compulsive).

Bruce, I have no suitable photos of an R-30-12-16 with Bettendorf
underframe. However, I'm sending you off-list a 4/48 photo of an
R-30-13-16 with twin-center-sill underframe which still had KC air
brakes. To model this car, you will have to rework the underframe by
using a Tichy u/f instead of the R/C u/f.
