All that remains of the once-vast T&P Railway yards is the historic 1912 depot which welcomed soldiers in both World War I and World War II, and at its height housed telegraph and immigration offices. To get to the museum located in the Ginocchio National Historic District, visitors must pass through a tunnel below the still-active Amtrak line and enter the depot, where an impressive collection of railroad artifacts awaits. Items include memorabilia from early passenger trains, exhibits detailing the large-scale manufacturing functions at the shops, and hands-on displays including a model train and pull whistle.
