100 Ton Corliss Steam Engine Listed on the National Register of Historic Places. Marvel in awe as you watch this engine run on steam. Its flywheel alone weighs 10 tons.
Steam & Gas are King in Pawnee! If you enjoy seeing these beasts working just as they did 100 years ago, Pawnee is the place to be. Our Daily Parade of Power is sure to delight you if you enjoy seeing machines that move. From Tractors to Tin Lizzies and more, our show has them.
Friends New and Old Above all, we have some of the friendliest people you'll meet. These are the folks that make our show run and make the old machinery hum again and bring life back to relics once cast aside.

The Show

The highlight of the year for all of us here at the OST & GEA is our May show. Our show has been described by some as "the best-kept secret in Oklahoma". We truly have something for everyone.  Here are a few of the many things you can expect to see at our show.
