An additional question : what are the grids, the railings on the "hump" in the middle of the cars : are they air-conditionner intakes, or rather exhausts from the (diesel) engine ? A friend who saw the pictures was thinking that, in cas of exhausts, we should put a little amount of "dirt" on them ! (Beside trains, I practice RC-tanks too : that's the explanation, because our tanks are "weathered").
Yes, they are exhausts. In general, the RDCs were kept much cleaner than freight locos. But here's one of the few examples I have that shows the exhaust on the Western Pacific, the road that worked the RDCs the hardest:
Happy to oblige. As long as you're detailing don't forget the safety chains across the nose and tail doors. One detail I haven't been able to figure out how to model is the operational nose shape on the units:
BTW do you recognize the location of the image in my previous post? It's odd for an RDC to be in San Jose (the photographer's claimed location). I can't think of a location where the WP would be so close to an SP station. Willow Glenn?
The end of the story : I decided to build a 50's layout (modern Amtrak 2-level cars look too "massive"), Massachusetts, (Boston, home of MIT ! ), I looked for all companies which operated there in the 50's ; I will use a 2-units NH RDC-train, a NYC GP7 and a NYC GP9 "long range" for freight, I saw them together on a picture of 1957 or 1958. I ordered my freight cars in Germany (Marsilius) : 40' Box cars "Single Superior Door" by MTL (Susie Q and C&O, brown) and 33' Rib side 2 bay hoppers (Full Throttle), NYC and Boston & Maine, I think they will fit ; 2 MTL cabooses, NYC and Reading (last one no more available at MTL, but one still in stock in Germany ! ). And my smallest curve will be 270mm radius (Rokuhan), and no S-curves outside of stations (and the "passenger platform track" will be the straight one from the turnouts), maximum slope 1.5% ; it seems logical that, if one RDC "solo" can "climb" 2%, 2 connected together should too, because there is no additional "passive" load. In worst case I will cut the "whiskers" off, I hope they will then stay coupled together, despite of this modification. Now I will order the engines at "Jörg Erkel" and ... please wish me good luck !

I got one of the new release TRE RDC's a couple of weeks ago. I tested it on a 195mm loop with a heavyweight car in tow and it did fine. No mod to the coupler. You should have no problem with you setup. I have one from the first run that will run on a layout with 170mm curves, but I have not tested it with anything coupled to it.
The first run is near silent running. The second is a little less silent, but I am pleased.
I preferred not to wait for a new version of the RDC's ; it's the same thing with (real, not model ! ) cars : everytime a new car appears on the market, it takes some amount of time until it's "debugged" ; the RDC's are at least 6 years old, but the modifications made to them are "young". My layout will not be critical with it's large curves (I took the largest available for my planning) ; and no other cars will be connected to the RDC's ; so I hope the worst think that could happen would be that I have to cut the "whiskers", or build a coupling bar. Or am I wrong ?

Thank You for the idea, I added the couplers to my order ; and because there are 2 pairs, I could (if necessary) try building a coupling bar by (super ? )glueing two couplers together, it would look more realistic than a simple "smooth" bar.
