This 4 pack of PRR 2DP5 trucks is designed to swap with the OEM truck frame of the Bachmann PRR P70 lighted passenger coach.  Just swap the pickups and wheel sets and reinstall for a set of accurate trucks for the car.  Roller bearing versions to follow shortly.

Any chance we might see similar trucks used by some southeastern roads?  The basic shape was similar but it didn't have the built up piece on the outside of the truck... examples can be found at the links below... I know I could employ several for my head-end cars if they were available...

As I have said before, I will model anything for anyone, provided they do the research and provide me with a model to measure or drawings good enough to make a 3D model from. I also need the model of car that you want it to interface with.  I can't just design a generic bolster that won't mate to anything.

I really cannot spend any time researching for roads that I do not need parts for.  Family tells me I spend too much time already, but if the info is provided, I can fit it in at some point.

I'd love to hook you up with some tower plans, but I just don't have any of the standard variety.

@glakedylan is sending me an HO version to of a different tower to measure...  and I think that the plans are standard but the exterior materials were different in many cases.

Again PRR is my home road- I'll model anything for that.  Eventually I will need them so research is in the effort anyway.  It's just hard for me to justify doing something I will never use.

I do trades though...  :D

Many thanks to @Lemosteam for his excellent work on these! My pile of 2D-P5s was delivered yesterday, and the unboxing provided some much needed joy after a not-so-great day yesterday.

I didn't have a chance to put them in the Bestine-bath yesterday night, so I'll be putting them in for their soak now.

Here are the 2DP5 roller bearing trucks mounted under the Bachmann car using the OEM wheelsets and pickups.  Powered up and lit- rolls as freely as the OEM trucks!

Got my first one done today. Compared here with a stock car:



Side note, the modified car had the steadiest lighting of the three in the consist.

Wow, looks great!  How did everything go together?  Any difficulties?

The metal inserts were a little challenging, but I only had to sacrifice one truck before I realized that I had to cut the braces off the ends. :facepalm: That allowed the sides to flex and take the metal inserts more smoothly, and also allowed enough spread for the axel to get in. Still amazes me that it's the most consistent lighting of all of my BMann P70's!

@eric220 ,

I was able to keep the truck intact (after breaking two trucks similarly). Put one indent of the pickup into the corresponding truck pocket and push the other end down. Once you get the other end near the second truck pocket, you push outward from the center of the bolster and down simultaneously, then snap the center in the slot. It's ok if you bend the vertical tabs a little in the process, the can be straightened. Clearing the slot of any RP artifacts is helpful.

As for the wheels, I hold one into the pocket and then I put a thin piece if brass strip between the end of the wheel and the metal pickup and push down on the wheel, this then spreads the truck with only the force it needs to let the wheel drop in.

Are you satisfied with them overall?

@Lemosteam overall I'm very happy with them! I need to order more!

Those cross braces at the ends of the trucks do make assembly quite a bit more difficult and prone to breaking. They're not on the American Limited 2D-P5's. Is there a reason that they're there?
