Big Boy rolls into Tama Iowa.

People came from all over. Long lines of cars rolled into town before the scheduled arrival, and long lines of cars waited to get out of town when it was over.

Maintenance.

Using compressed air from the engine, bolts on the large wheels were tightened. Cameras and smart phones were everywhere.
