There is a lot of interest in this engine, both 3R and 2R.
UPDATE: MTH has announced secretly at York that they are looking at their 2015 Volume 1 catalog to announce their 44-Tonner with PS3. Will it be 2R and 3R? Only 3R. That's too bad considering it had PS3 electronics (DCC included) and a correct, scale hood-width, which the WBB lacks.
Rich Yoder previously brought these out in brass years ago (now sold out) and they can be had on the secondary market pretty regularly. Sunset did these as well even longer ago, but I believe they didn't run well. Rich Yoder's 2R sold well and the 3R did not. The main complaint by 3R modelers was that it didn't come with command control and buyers gawked at having to do the upgrade themselves in such tight spaces. The 2R models could be upgraded to DCC with similar work, but there wasn't the same kind of griping by 2R modelers as HO decoders would work with this low-amp model.
There were rumors for a long time that MTH would bring this model out with their PS3 (would please both 2R an 3R command users), but while they admitted publicly that they wanted to do this model, their developments have been slow and no one really knows if MTH is still trying to pursue this model in their list of imports. (Seems doubtful after this last catalog, right?)
Now in April 2014, here comes Williams by Bachman, producing a scale 44T in plastic. Its somewhat surprising they're doing this since WBB isn't known for scale items (the scale-ish GP30's were also an interesting step.) No command control and no 2R models. They also didn't mention phases, but this one looks like a Phase IV prototype with the grills and no door in the front that I believe was the Phase I model.
I took some photos at York of what they had on the shelf for others to make their own judgements.
My opinion?
-3R's that don't use command control will like this and 2R straight DC guys might find this worth converting (the photos show scale wheels ironically), but the command crowd is going to need to look at a "sacrificial" modelers to see if someone can convert these at all.
-I have my doubts that it can be easily converted to 3R TMCC and sound with ERR's sound commander 2 (SC2) demise. No doubt the speaker in the fuel tank will need to be replaced with a small one and placed elsewhere to make room for electronics (if the fuel tank they have is even big enough...Rich Yoder had to enlarge his for the 3R lighting/directional electronics.)
-2R DCC guys that also want sound could probably get away with a soundtraxx Tsunami-750.
Alas, here are photos for you to make your own judgments. I wish WBB well, but with MTH's announcement that we're 6 months or so away from them announcing theirs, WBB will be threatened by all of the folks who want a command version with sound. Perhaps the market is still big enough for both.
As always, click the photos for higher resolution.
