If you mean Northeast Narrow Gauge in Wiscasset, Maine, yes, they have discontinued all rod driven steam locomotive models. I ordered one a few months ago when it was still listed on their web site, and they telephoned to tell me that it has been discontinued but their ISP hadn’t updated the site.
A news blurb here a couple of weeks ago indicated that the owner is having health problems.
I wonder if there’s any chance that Marklin/LGB might start making Porters again? I seem to remember that they said that the ToyTrain line would be discontinued, but the final Porter that LGB made was not part of that line…
I noticed yesterday that some Northwest Narrow Guage kits are showing up on E-Bay. Is this the same company? They have a galloping goose and rail truck among their offerings.
