That’s cheating!! 
Again…a very wonderful work of art, ruined by an operating train that starts up too fast, and runs too fast.
Picky picky Fred!
Thats just Nuts, I must have one 
Didn’t watch the whole video, but did they mention how many total hours - designing, cutting, assembling - they have into this thing? Probably used a machine with a bit more umph than ours has.
I think I heard in the banter that the O Scale version was available now. Didn’t hear a price.
Almost makes you want to change scales, doesn’t it?

A laser machine is the funnest tool or toy you could ever buy even for garden RR. Even drawing and planning the parts up are lots of fun.
I am in the process of making a wooden cab for my Unitah 2 6 6 2 , making a larger coal box. So it will end up being a 2 6 6 4 when I am done.
Lots of fun making all your windows and doors stairs and hand railings, Imagination is your only limit.
Costly though

Lasercut window frames for my superliners. Start making friends with your local architecture model maker. my windows cost 100.00 cut acrylic and black window frames
Unfortunately, like everything else these days, one needs a university degree to run a ‘simple’ plastic/ply cutting machine. I am sure a laser cutter is superb but turning binary zeroes and ones into actual laser cutting guidelines is the hard part.
