One - an older MTH Alco DL-109.
Two - if you count the old former-PS1 RK Doodlebug, with a "warbonnet" (more of a "war cap") nose and green body. I say "former-PS1" because I bought it on my only York trip in 2005 or so from the MTH parts booth for $20. It had been stripped of motors and all electronics, but was otherwise complete. Pretty good bargain. Of course, I've never done anything with it - if I do it will be re-painted or re-lettered or both. Then towed around by a 2-8-0 or such, as that is what happened to most Doodlebugs eventually.
(Correction! I also have a Marx plastic A-B-A E-7 "set". Whew! Glad that's on the record, though I bought them because of the Marx angle, not the Warbonnet.)
