RDC Phases?

So I just got done with a midterm and to relax I am leafing through NP In Color Vol. 2, admiring the NP's RDCs. Then something catches my eye...

Most of the RDCs pictured look like all the other RDCs I've seen and the MARC units I saw as a boy in person - flat faced with a flat area above the nose door with an inset headlight. But one of the NP units, RDC3 B-41 is different. It has a very sloped front roofline with a headlight that tapers out and above it at the front. It also has windows on the nose that aren't as tall as the rest and numberboards above them where the other units have no numberboards at all. And, the corrugated sheet that is on the side of the unit under the window line, is used on the side doors (the other units have no corrugation on the side doors immediately behind the nose) and the corrugation wraps around the nose and meets at the nose door,

I know the WP units, which the NP purchased and the Kato models are of the simpler design. Was this a feature of the RDC3 or did the RDC design have phases?

I looked around online and found some pics:

Unit with fancy nose:



Unit with plain jane nose:

Now seeking Pacific NW N scalers to create a Modutrak-style modular club featuring NP's shared mainline between Seattle and Portland. PM me if interested.

I'm no expert, but you are correct. There were at least two versions of the RDC. I believe the lower version was the earlier phase.

I think Frank has it backwards, but yep, there were multiple phases.

Athearn did the other one in HO, that's how I know about them, but I can't quickly find a pic online (google fail...).

Yeah, IIRC one phase has the larger windows on the end. There may be other subtle items but I think the ends demark the two primary "phases" (all based on my google research, which may or may not be reliable).

The headlights and fluting on the ends too. Those are the giveaways for me.

I like the fluting and headlight on that version.  My all time favorite is this one.  So ugly it's cute:

Mark hit it right on the head as far as two phases.  The phase II had smaller end windows, the headlight moved up (in part because some roads wanted diaphragms on the ends) and had the number board moved to the front.  Also there was a slight redesign of the radiator bulge which included additional screening being applied to it, changes to the stainless steel trim around the doors and and some cars (but not all by any means) had additional corrugation over the vestibule doors and wrapping around to the front (PGE/BCOL are great examples of this).  While the raised headlight part is available from Miniatures by Eric I wish that somehow we could get the other parts needed to really do a correct phase II.  At one point there was talk of someone doing it but never saw it completed.

I'm wondering if one could photo etch new ends for the cars? It could probably done so that one wouldn't have to remove the end of the car.

The headlight shroud was a key spotting feature of the Phase II cars.  Miniatures By Eric has just released resin parts for the headlight shrouds and the RDC pilots.

You would be better off if they were done in resin... trying to apply an etched piece would still mean that you have to dress it up around the part so as to make it smooth, which would be very difficult.

Here's another great example of a Phase II with all the trim, BN 2350...

Compare the detail to the Kato RDCs and you will see a number of differences, aside from the wrap-around corrugation.
