The Pennsylvania Trolley Museum came to Chartiers Township, Washington County in February 1954 with three trolleys and a dream that was born in 1941. Today, the museum now boasts a collection of nearly 50 cars, over 600 members worldwide, 150 active volunteers, and over 30,000 visitors each year. During the months of April, May, and September - November we are only open Friday - Sunday from 10 AM - 4 PM.
