This may be old news to those of you who are MR subscribers but I found out today from my historical socieity that Walthers has advanced reservations available on some limited run Mainline SW7s in 6 roadnames. (Release date: Late May '21) Each roadname is being offered in both DC & DCC. The sound versions will be outfitted with “ESU(R) Sound”, which I presume is Loksound 5, or a paired down version of it. I don’t see an undecorated version offered with this release.
I have an undecorated non-sound Mainline SW1 that Walthers released a few years back. It has nice detailing, good weight for pulling, and is a very smooth runner. I expect the SW7 to be similar in all three categories.
I’m not a big fan of Walthers rolling stock but I’ve been quite happy with the few locomotive offerings that I’ve picked up from them over the years - going back as far as the original release of their SW1 in the early 90s. Good detailing and a great little puller.
FWIW…
