The museum is "dedicated to the preservation of original Phoenix trolley cars and memorabilia, and to showing their place in the history of America's fifth largest city."

In 2016, the City of Phoenix declined to renew the museum's lease for another five-year period, and the Hance Park location was closed.

[1][2][3] In 2018, the museum relocated to a site in Phoenix's historic Grand Avenue Arts and Small Business district, along one of the earliest trolley lines in the city.

In December 2020, local businessman Mike Bystrom contacted the museum asking if they were interested in a storage unit that appeared to have been built around the body of a street car.

Bystrom generously offered to donate the street car and pay to have it transported to the Grand Avenue site of the museum, where it sits today.
