Streetcar operation at the museum was inaugurated on May 19, 1991, using ex-Fort Smith Light and Traction Company car 224, a
Birney-type streetcar built in 1926 by the
American Car Company. The initial line was about one-quarter mile long, using ex-
Frisco freight tracks, along which FSSRA volunteers had installed
trolley wire and support poles. It connected the carbarn, at 100 S. 4th Street, with the
Fort Smith National Historic Site. This extension, from the line's east end, more than doubled the length of operational track, making it about . This short extension included a crossing of Rogers Avenue, and the city council funded the cost of the crossing installation, citing the line's value as a
tourist attraction. The first extension since 1996 was opened on November 24, 2002, starting with a curve just before the previous terminus at Garrison between 3rd and 4th streets and running along the south side of Garrison Avenue, to 2nd Street. This is within the
West Garrison Avenue Historic District, which is also listed on the NRHP. At the other end of the line, a very short extension in May 2005 took the track across Wheeler Avenue to a new terminus at 7th Street, making the line about in length. A much longer extension from there was planned, which would take the line north along 7th Street. The line's first extension since 2005 opened on May 21, 2016, bringing into use newly laid track and trolley wire along 7th Street. The line's new eastern terminus is on 7th Street at Rogers Avenue, and the approximately 750-foot extension made the full line about long.
