This is a custom/kitbash for the Sonoma Mountain RR layout. It's a Timberline 3 stall engine house kit that had to be modified to fit a specific 3 track space next to the turntable on the SMRR layout. The original square exhaust stacks were replaced with custom made round stacks. The corrugated shed is an add-on the owner requested. Door hinges and nut/bolt details were add-ons. The large roof side was done 5 times due to warping issues after applying the tarpaper material. I ended up cutting the metal case/cover from a VCR to use as the roof and using a different brand of tarpaper. Although too late for this build I did get a roll of Suretape CP743 that I will use next time for tarpaper roof work. Both sides of the roof are removable for viewing the future interior. The hardest part was building the windows! I can't say how many times my fingers accidently poked through breaking the mullions. There is hardly any adhesive on those small parts! I have a few touch-up areas then I have to ship it to the owner. Wish me luck on shipping!
