Joe Congemi postedI second that Tom. I'd also like to see 3rd Rail do an N&W K1. They've done and K3 and K2a before so it would seem a logical choice.
The K1 is on my short list too. Along with the Z1b. Since this 0-8-0 was common to C&O, VGN, and N&W I had hoped that it would have a better chance of being produced.
