Jim, Ed & all... Sorry to have dropped off the list on this for a day. I've been busy earning a restaurant consulting buck or two in order to stay "retired". Now back to "real" fun. I offer the following only as additional information and not to dispute anything previously posted.
As best I can tell, the DPH truck REALLY IS a 41-CUDO-11 truck. I was not privy to the history of development of this truck by Larry, but Railway Prototype Cyclopedia Vol. 6, page 98 has four photos of this truck. The DPM castings are identical to these photos, right down to the very small details on the side frames. That said, there is virtually no visible difference between the CUDO and CDO truck (slight difference in the mounting casting of the bolster anchor). The NDO truck is also slightly different but still very close. The DPH/BB truck could pass for any of these three types. The DPH/BB truck uses some outstanding castings and exhibits much better detail that either of the AM 41-N-11's. There is a real need in S scale for both of these trucks, depending on which RR you model. The 41-CUDO-11 designation simply means it is a 4 wheel, single bolster truck on a 9' wheel base with 14 1/16" pedestal openings, DISC BRAKES, OUTSIDE SWING HANGERS and 6" X 11" roller bearings. All of this Pullman "speak" is explained in Vol. 6 of RPC. The key differences between the AM and DPH trucks are the Disc brakes and outside swing hangers, per Jim's comments. Also note, there are no external brake cylinders on the prototype CUDO/CDO/NDO trucks. These trucks were primarily used after 1954 mostly by the UP on both new and rebuilt cars. The 41-CDO-11 was used primarily by the ATSF. The NDO truck was used by B&O, CB&Q, NP, NYC, and SP&S. The 41-N-11 is a four wheel, single bolster truck with an 8'-6" wheel base and 6" X 11" roller bearings. They had clasp brakes with externally mounted brake cylinders/slack adjusters. These trucks were one of the most commonly used trucks by all three car companies and were applied to cars built between 1946 and 1955. 41-N-11 trucks were used by A&WP, ACL, B&O, C&NW, C&O, CB&Q, D&RGW, Erie, FEC, GN, IC, L&N, MKT, N&W, NYC&StL, PRR, RF&P, SAL, SP&S, SRR, and WofA. Note that the sprung AM version of this truck has an undersized brake cylinder and that it is mounted on the wrong end of the truck. That's why they still need the addition of the brass BTS parts to be correct. Now THIS is truly TMI, but we should try to get as much info as we can, in my opinion, on any subject we model. Must be the old rivet counting narrow gauger in me.
