Our club just participated this past Sunday in a small local train show here in Milford, CT. Was a little apprehensive about asking to bring my 12 year old grandson to participate in all the stages of setting up the train modules, running and tear down. NO PROBLEM!, his small size and youthfull physical abilities allowed him to get under the modules and hook up all the electrical connections with no problem. I don't think there was a club member he did not assist in some way sitting up their modules with his youthfull exuberane.
