Sean,
That's really nice work, congrats. And I love that sector switch.
I'm considering building something similar but have put it off for security reasons. What would it take to punch a hole in the top or side of your structure? And is it light enough to be carried away by 2 or 3 men? I'm really curious to know if you've considered security for this structure and if you've taken some steps to make your engines secure when your away (or asleep)?
Honestly, I'm not trying to rain on your parade but my concerns about security have kept me from going forward with my own plans for an outdoor on-site rolling stock structure.
Please share your thoughts.
Thanks,
Walt
