Reminds me of this guy with his 5" gauge gas locomotive. Runs on a 3.5 HP Briggs flathead, so it's still on topic. It's the Mini bike of the rails!
The guy also has a coal fired, steam powered mini locomotive.
He needs to fabricate automated crossing gates where the tracks cross over the sidewalk.
I've often thought about putting in a couple of miniature golf holes in the yard, but this train seems like more fun.
Like I really need another project my plate.
Sorry for hijacking the Flo Jet topic.
