@haasmarc I have not built it yet but am looking at the possibility of a Berkshire Locomotive adding a 2 axle pilot and modifying the shell as needed
not overly concerned about the locomotive length, just something that resembles a T-1.
The bigger challenge is the tender, for which I will have to slice and dice and add or build from scratch, as it is much longer than any
tender that I am aware of currently available. and the tender trucks will be a challenge unless there is something close to them in
3D printing, or a cheap find on the vowel-bay.
Everything is rather tentative at this point, but making an inventory of what is needed in comparison to what is available.
Sincerely--
Gary
