JOPLIN -- Hundreds of miniature replica trains were on display at he Joplin Museum Complex Saturday. Locomotive enthusiasts of all ages were able to buy, trade or just appreciate all of the different types of models. Some of the small engines running the tiny tracks are worth thousands of dollars. Replica railroaders say the miniature locomotives make great decorations circling your Christmas tree. Organizers plan to host another train show at the Joplin Museum Complex in March.
