The meet, which began Saturday and ends today at the Ontario Convention Center, attracts train collectors throughout the West looking to buy and sell model trains.
"As you grow older you don't have to grow up," said Jerry Moser, a member of the toy train club sponsoring the meet.
This is the first year the meet has been held in Ontario. It was previously held in Pasadena for 31 years.
"So we've moved out here and intend to stay here as long as we still could have the hobby," said Jerry Pearson, president of the club.
A variety of trains and accessories are on display or available for purchase at the meet, including items from such manufacturers as Lionel Trains, Mike's Train House, Bachmann, Atlas O and 3rd Rail.
The Grand Canyon Model Railroaders, the Train Collectors Association Western Division and the Southern California S Gaugers, along with the sponsoring group, have operating train layouts on display, where collectors can see the trains in motion.
"These are expensive trains," Pearson said. "Some of them are very rare. If you go around the room you'll see sets for $15,000 and you can see sets for $20. So there's a wide range of stuff. "
The rarity and condition are key factors in the pricing, he said.
"Condition is everything," Pearson said.
The event is the largest toy train meet in the West, he said.
Meets typically have 350 to 400 tables, but the event has downsized some since some collectors began using eBay, he said.
"The advantage to this meet is you actually get to see, touch and smell," he said.
