Visitors can arrive as early as 9:30 and watch our steamers "Steaming up," building their fires and the steam pressure needed to operate. It takes about an hour or so, and this is the perfect time to ask the builder/engineer/fireman the many questions that come to mind about that mystical era of steam power. We welcome the public on our Run Days. These are typically the second and last Sunday of the month but there can be exceptions!  Please be certain to check the calendar to make sure that you arrive on the correct day.
