224 is a streetcar (or trolley) in Fort Smith, Arkansas, listed on the U.S. National Register of Historic Places.

The Fort Smith streetcar system used several Birney-type cars during the last several years of streetcar service, until the abandonment of the system by the Fort Smith Light & Traction Company on November 15, 1933.

[3] Car 224 was restored by FSSRA volunteers and began carrying passengers on the museum's heritage streetcar line on May 19, 1991.

[2][3][4] The FSTM streetcar line, or trolley line – the terms streetcar and trolley are used interchangeably in much of North America[11] connects Garrison Avenue, in downtown, with the gates of the Fort Smith National Cemetery.

The 600 Volts DC that powers the car's electric motor is collected from the overhead trolley wire via a trolley pole on the roof; only one of the two poles is in use at a time, depending on the direction of travel.
