Has bachmann considered manufacturing models of Donald and Douglas. Both engine and tender shell could come from the same tooling, and the 0-6-0 running gear would be virtually identical to Thomas, as well as James; minus the lead trucks.
Bachmann hasn't announced or confirmed Donald and Douglas models for the Bachmann Thomas range. Plus as much as I would like to see them made, I don't think Donald and Douglas are possible for the range, but you never know.
That they are Chazzie boy, that they are! :D
