| • | 122 was built to a standard American design by the J. G. Brill Co. of Philadelphia in 1909 for export to Porto, Portugal. |
| • | Rosie is similar to early streetcars that once operated in Dallas. |
| • | 122 was retired from service in Porto in 1978. |
| • | MATA Co-founder Phil Cobb saw 122 operating in the San Francisco Trolley Fair. He bought the car and had it transported to Dallas. |
| • | At 28-feet long and 14 tons, Rosie is the smallest car in the M-Linefleet. |
| • | Rosie rides on a single Brill 21E truck with a 7-foot wheelbase, and 33-inch diameter spoked wheels. |
| • | She has two 600-volt DC, 35-horsepower 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 M-Line cars that have two trolley poles, Rosie has only one. |
| • | We 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 limited regular revenue service. She provides back-up service for our other trolleys and operates during special events |
| • | She is popular with our riders.. |
| • | Rosewood Properties and the Crescent, #122's sponsors, named her the "Crescent Rose." |
| • | M-Line operators began to referring to her as "Rosie," and soon the naming of our streetcars spread to the rest of the fleet. |
| • | Rosie celebrated her 100th birthday in 2009. |
