This season, he completely demolished last year's set-up and made an even bigger display, with three tiers and three tracks instead of just two.
"It's still a really great winter hobby for me," Zan Wills said, noting he was especially inspired by the Wise Avenue train garden in Dundalk.
He explained the set-up would normally take six months to build, but between school and soccer practice, he only had six weeks.
"I am very happy with the way it turned out," he said. "I really just enjoy building it, I enjoy running it and seeing the looks on the little kids as they come in. It's really neat to see them with all the trains."
"I am definitely going to keep doing this as long as I can," he said, adding he hopes to get different buildings, different engines and maybe change the track layout next year.
