More than 200 people had participated in the “Wheels That Move the World” exhibition Friday at the Lehnis Railroad Museum, and things are only just beginning to roll.

The exhibit continues today and Sunday with more than 25 vehicles from the arenas of military, law enforcement, emergency response, agriculture, construction, railroading and basic transportation.

“We’ve had a great crowd today,” museum curator Beverly Norris said, with almost two hours remaining until closing time. “They are letting the kids climb into the military vehicles, and there’s so much to see.”

A group of adult-sized Big Wheels for older attendees were proving popular, and adults especially were being drawn to heavy equipment on display across the street from the museum.

“They are things that we don’t always get to see up close,” Norris said. “It’s a chance to see some of that big heavy equipment.”

Admission is $5 for adults and $2 for children age 5 and up. Younger children are admitted free.

Food trucks are also on hand offering snacks and refreshments.

The inside of the Lehnis Museum is open with a telegraph exhibit and touchable tools from the early railroad days. Also on display inside are a heavy-duty pickup, a four-wheeler all-terrain vehicle, a motorcycle, and a sports car.

The museum’s mini-train will be running, with rides available for $2 per person. In addition, a trolley takes guests to see a locomotive in the BNSF yard.
