New Zealand's most detailed mini railway exhibition is steaming into Auckland this weekend.
One of the country's biggest enthusiasts has been working on a special project for the show.
It started out as a hobby, but it's grown into more of a lifestyle for model train enthusiast Barry McCullough.
"You get involved with it and time just disappears," he told Newshub. "It's quite enjoyable."

His most recent project was a mini amusement park, complete with a log flume, a Ferris wheel, go karts, and hundreds of tiny figures - a time-consuming procedure.
"To stand up one of these people down here, you're normally looking at about three minutes," he explained.
"You might put one down and it might take 15 seconds, but the next one will fall over and fall over."
It'll be ready for the exhibition this weekend, and he says all the hard work is worth it.
"When it's all finished it looks right, and that's the most important thing."
Mr McCullough gets his inspiration when he's out and about. One of the models, showing a rescue helicopter saving a person from the water, even has a story of his own.
"I used to be in Search and Rescue, and it just brings back memories of stuff that we used to do."
His friend and Auckland Marklin Club president Phillip Wrigley says their model will be one of the biggest on show.
"If not the biggest, with 18 of these modules, and there'll be other big ones from other clubs."
Those planning to attend the exhibition are in for a treat, Mr McCullough says.
"I think they'll be very surprised, and they'll be thinking, 'When's the next one?'
The exhibition will be on at the Te Atatu Penninsula Community Centre this Saturday and Sunday.
