Fir some reason my prior comment didn't post. So let me try again.

I've been involved in tourist railroads and rail museums for over 50 years. I've also been involved in Class I railroads, including FRA regulation, for over 40 years. If you are involved in tourist railroads/museums. you need approach it as real railroading with all of the potential hazards that can occur on a "real" railroad. It's not a "toy". If you are approaching it as an old man's toy railroad, you should confine yourself to model railroading.

Agreed, the human body doesn’t differentiate between 10 tons of steel or 110 tons of steel, the end result is the same. As such, anyone out there “playing trains” is dangerous and is the reason for standards and inspections. If anyone is naive enough to think that there aren’t any accidents out there waiting to happen, go surf YouTube.
