Well Dave, I've been involved in the railroad motive power business, both steam and diesel, for more than 53 years, and must admit that I NEVER heard of that "group". I am aware of, and have assisted, the group working towards manufacturing a NEW PRR T-1 class 4-4-4-4 duplex. They have all the drawings and technical data, and have already produced at least one cast driver center.
In my opinion, a Hudson, would NOT be a practical steam locomotive for today's excursion operations, as it would not be capable of handling a train large enough to generate ticket revenue. Steal locomotives with eight drive wheels are pretty much a necessity for today's main line steam excursions.
