Thousands of visitors. Hundreds of machines. Every August along historic Route 40.
The Annual Steam Show is our flagship event: three full days of antique equipment, live demonstrations, entertainment, vendors, and the largest historical construction display in the United States. Thousands of visitors from across the region and beyond make the trip each August.
2026 Theme: Silver King. Each year the show honors a different piece of equipment history. This year we spotlight the legendary Silver King tractor, a rare breed built in Ohio from 1935 to 1955, known for its distinctive silver paint and rubber road wheels.
From a small John Deere garden tractor to a massive Caterpillar D9 dozer, the variety of equipment on display is unlike anything you'll find anywhere else. Most machines are operational, and many are put through their paces right in front of visitors.
The showgrounds are located at 222 Spring Road, Brownsville, PA 15417, just off U.S. Route 40 in Washington County, PA. Easily accessible from Pittsburgh (~45 minutes) and the surrounding tri-state area. Follow signage from Route 40.
