Steaming across the Rockville Bridge

“Steaming across the Rockville Bridge” was taken in July 2026 in Harrisburg, Pennsylvania. The Union Pacific 4014 Big Boy is seen here going across the Rockville Bridge, commemorating its coast-to-coast America 250th journey. This Big Boy is the largest steam engine in
the world, and the Rockville Bridge is the longest stone arched bridge in the world.
