My son just turned 10 years old. I told him about my hobbies one was a toy train he thought that would be fun but to find one here in the DR is next to impossible. My niece in Canada found an old one is someone’s basement and brought it down to my son. Then he started to work 95% was his project I only help with supervision and electronics. He videoed the train one night and another child uploaded it to you tube of course he does not know how to spell but I think they had fun. Here is his project and still looking to expand.
