Rod Stewart (inset) has been working on a model train layout for 20 years. He’s almost finished and featured in the new issue of Model Railroader magazine.

Rod, 69, is an avid model railroader. Talk about riding’ that train.

The iconic singer finally reveals all about his hobby in the upcoming issue Model Railroader magazine. Stewart has been quietly working on a super train set on the third-floor of his Los Angeles home for 20 years, and he has no plans to quit yet.

“People are in such wonderment about it because it’s such a juxtaposition between rock ‘n’ roll and model railroads,” he tells the magazine.

And, no joke, it’s an obsession. On the road, Stewart demands a separate hotel room for his trains. He takes cases with him, filled with model train kits, tools, and paint.

His tour routine consists of a morning workout, an afternoon working on his trains, and an evening performance.

“For three or four hours a day I’m in heaven, absolute heaven,” he says.

In fact, Stewart says he asked his dad for a model train set for his 15th birthday. Wouldn’t you know it, his dad surprised him with a guitar instead. “That guitar worked out pretty well for me,” he says. But he never gave up his passion for trains.

Stewart’s train set is laid out on a platform six-feet wide and 26-feet long. The scene is a town in the 1940s complete with period buildings, cars and steam trains.

He says it will probably take him three more years to finish the last section.

“We’ve got a lot of ideas we’re kicking around, but the biggest problem is going to be getting from the city into the next scene,” he says.

“It’s a difficult one, because the city got bigger and bigger and now it can’t go any further, otherwise it will just be a city and no railroad. But we’ll come up with something.”

So is it called “Stewartville?”
