centennial. A 501(c)(3) non-profit organization, Old Pueblo Trolley (OPT), was formed to raise funds and coordinate planning with the city and business community, and volunteers also donated time to move the idea forward. The Old Pueblo Trolley heritage streetcar line was inaugurated on April 17, 1993. Two trolley cars were available for service when the line opened, and were operated in the inaugural runs: Car 10, a 1918-built Birney-type car that was ex-Pacific Electric Railway 332 and was under lease to OPT from the Orange Empire Railway Museum since 1985, and car 255, ex-Osaka, Japan (Hankai Electric Tramway), which was built in 1953. Car 255 had been in service in Osaka until June 1992. The Birney car used a trolley pole, while the Japanese car used a pantograph, as it had on its home system. Before entering service, Birney car 10 was repainted from PE colors into the old livery of the former Tucson streetcar system, whose fleet had included an ex-Douglas, Arizona, Birney car of the same type, which was in service until the abandonment of the old Tucson system in 1930. Car 10's lease had started in 1985, but restoring it to operating condition took time and money, and only in 1991 did the car operate in Tucson for the first time under its own power. Before the start of public service in 1993, the Birney car operated occasionally for special events, for members of the OPT group. The line that opened as a heritage streetcar in 1993 used a combination of old, abandoned, paved-over track along University Avenue that was uncovered and rehabilitated, and new track along 8th Avenue and along 4th Avenue. Most of the line is two-way single-track, but it includes some double-track. Workers from Tucson Electric Power installed the overhead trolley wire, in some cases as volunteers.

Regauged from 900 mm to standard, restored to its original double-end configuration, and painted to pass for the very similar Prescott and Mt. Union №1. Fleet changes Car 10's lease from the Orange Empire Railway Museum expired in March 1995, and the museum was not willing to extend it, so car 10 ran in Tucson for the last time on June 4, 1995, and was moved back to OERM on June
