We often lament the fact that Pittsburgh no longer has trolleys. The closest we have these days is The T, and due to its limited operating area, is only really useful for a few neighborhoods in the city (and beyond).
For those nostalgic for days when trolley transportation was the norm, you are in luck- The Pennsylvania Trolley Museum in Washington shares the history of this transportation method with informative and interactive exhibits and a massive collection of trolley cars in their showroom.
But for those looking for even more, this one comes with a fun twist- you can even ride one of the historic trolley during your visit!
