When I was in Saipan there were remnants of a system like this, including a steam locomotive hulk. It looked like it was the prototype of the old Ken Kidder 0-4-0 "Mudhen". I've got both of the HOn3 versions - with and without tenders. I know I've got black and white photos. I'll find them and post them in a later blog.
This is delightful video from Cambodia that shows that there is a prototype for everything
- even 0-5-0 operation.
Hang on for an exciting ride
