I actually rode a local museum steam railway this weekend where 6 of 8 staff members were children aged 10 to 15-ish - the driver and head conductor were adults. They seemed to do their tasks quite well. And they took them dead serius. Felt kinda strange having a 10yo in uniform with a serius face marking your ticket.
