Not all at once, I want to identify the correct prototype trucks for the passenger cars that we currently offer, as well as the ones in development, but eventually, we probably will. This list has grown even longer on my spreadsheet. I also ordered a volume of the Railroad Prototype Cyclopedia that has extensive information on Passenger Car Trucks.
I did find this, but it doesn't seem to match all the variants:
PULLMAN PREWAR CODE:
A - Any truck used at an articulation
U - Truck used under specific Union Pacific-assigned cars
41 - Four wheels, one bolster
43 - Four wheels, triple bolster (SP, UP, PRR, etc)
62 - Six wheels, double bolster
63 - Six wheels, triple bolster
E - Elliptical (leaf-style) bolster spring
H - Helical ("coil"-style) bolster spring
R - Equipped with roller bearings
X - Experimental
11 - 6"x11" journals (5.5"x10" were standard)
PULLMAN POSTWAR CODE:
No designating letter indicates standard 8-foot six-inch wheelbase
A = 7'0"
B = 8'0"
C = 9'0"
No designating letter indicates clasp brakes
D = disk (rotor) brakes
No designating letter indicates 15-1/16" pedestal liner openings (jaws)
N = 13-3/8"
M = 13-7/8" (Milwaukee Road)
U = 14-1/16" (Union Pacific)
No designating letter indicates helical ("coil") bolster springs
E indicates elliptical
P indicates combination of helical and elliptical (Pennsylvania, as on new Walthers "Broadway Limited" cars)
No designating letter indicates no roll stabilization
S = roll stabilizer
No designating number indicates 5.5"x10" bearings
11 (as suffix) indicates 6"x11" bearings
No designation indicates inside swing hangers
O = Outside swing hanger
