I've made a little progress on the next frame forward, frame 140.
This frame is actually identical to from 156.5, except two of the engine cars hang off this frame. I don't know if I'm going to include the support struts now, or wait until I'm attaching the engine cars.
Either way, I think I'll leave all the frames on the wax paper until I'm ready to put it all together.
Cheers,
John Gay
