Car 122 / Rosie
- 122 was built to a standard American design by the J. G. Brill Co. of Philadelphia in 1909 for export to Porto, Portugal.
- The car is similar to early streetcars that once operated in Dallas.
- 122 was retired from service in Porto in 1978.
- At 28' long and 14 tons, Rosie is the smallest car in MATA's fleet.
- Rosie rides on a single Brill 21E truck with a 7' wheelbase, and 33" diameter spoked wheels.
- She has two 600V DC, 35 HP traction motors: an 1890's vintage clam shell design, each held together by 4 bolts.
- 122 uses a type B controller, that provides regenerative braking.
- Unlike the other MATA cars that have two, Rosie has only one trolley pole.
- MATA retrofitted Rosie with a WABCO self-lapping brake valve and a GE compressor.
- She was extensively overhauled in MATA's shop in 1990-1992.
- Because of her age, Rosie sees only occasional revenue service.
- She is popular for charters and is operated during special events.
- Rosewood Properties and the Crescent, #122's sponsors, named her the "Crescent Rose."
- MATA operators began to referring to her as "Rosie," and soon the nicknaming of our streetcars spread to the rest of the fleet.
