When you’re on a streetcar and it breaks down, who do you call? If you’re on the United Electric Railways in Rhode Island, you called in EMERGENCY car 1504. A true AAA tow truck of the trolley era, 1504 is fully equipped to repair or move any disabled equipment quickly and effectively. From spare trolley poles and headlamps to jacks and axle dollies, this car had it all! 1504 has been undergoing lengthy restoration at the museum for over a decade, and is now complete and often on display.
