I would love to see 3rdrail do another J3 Hudson with PT tender but with a regular smoke box door. I would also like to see 3rdrail try again for a NYC H10 Mikado. I wasn't ready the first go at it but I am now. I know MTH came out with a Mikado last year and Lionel is doing one this year but Brass is king.
Post what projects you think Scott should tackle next.
