Budd RDC powered trucks

finding those Sunset RDC trucks will be very difficult if Scott has no extras. what can be done is getting the flat can Mabuchi, gearboxes and wheelsets from NWSL. finding your appropriate sideframes will be your next step.

the Sunset truck has been used on their RDC and newer Brill Doodlebug.

Thanks for direction.  I will try NWSL and see where we go from there.

I am guessing that your search is in conjunction with your Metroliner project;  if so, I would like to offer the following opinions and suggestions:

1.  In my opinion the RDC truck does not convey the 'look' of the GSC trucks used under the Metroliners, with its more massive equalizer.  I would suggest instead using an AAR Type B road truck, as used under, inter alia, RS3's, FA's, U25B's, etc.  Ideally you want one that had Timken AP bearing caps -- but if you can't find one modifying another rb truck will have to do.

2.  I presume you want the truck internally driven, so that a full interior can be fitted, which sounds like a good idea.  This also suggests you may be powering each car, which adds a lot of complexity -- just like the real ones ! -- and which I think is less desirable.

3.  Combining 1 and 2, I would approach this project by powering only the snack bar coach(es), using a central frame mounted motor and low level drive shafts to each truck -- as the earlier Weaver RS3's and FA's used.  I'm aware that many of thes Weaver units need a gear rebuild, but that's a solvable problem in my opinion.
     Most Metroliners [ not in "Capitaliner service" to Harrisburg ] ran in 'fixed' six car formations:  From the south [ DC ] end, two parlors; a coach + snack coach; and two coaches.  Sometimes the last two pairs were reversed, and 2X (coach + snack) was also common, esp in the earlier days.  Hence, a Metroliner would always have 1 snack in the consist.  If your consist would also operate in one direction [ eg, loop to loop ], it may also make the pantograph construction easier -- the less coaches [ with the Stemmen pans, not the single arm type ] with functional [ raised ]  pans the better [ I presume you're aware that the car's pans were bussed within the back to back pair, so only 3 were raised on each 6 car train.]

Again, that's how I would approach things.  And as they say, YMMV -- Your Models May Vary.   Especially if your query wasn't for Metroliners in the first place !!

Find a set, make yourself an RTV mold and cast up as many sideframes as you need in either resin or Cerrobend; use some brass bearings for the wheelsets,

If this were 2 rail, I'd suggest getting a handful of Q-car components to build your own power trucks and maybe you could still do that if you could swap out the wheelsets.
