Starting in 1921, Baldwin-Westinghouse supplied two types of electric locomotives to the Companhia Paulista. Two of the passenger variant with the wheel arrangement 1-B+B-1 were delivered in 1921 and were numbered 212 and 213. In contrast to the C-C freight variant with six traction motors, each powered axle of the passenger variant had a twin motor with quill drive. This explains why 212 and 213 had more power than 214 and 215.

A third passenger locomotive was delivered in 1925 and numbered 216. Up to two of them could operate in multiple. Later the Paulista renumbered them 310 to 312. When Fepasa was founded in 1971, they received the numbers 6311 to 6313. At this time, they had already been designated mixed service locomotives since they were not fast or powerful enough anymore for pure passenger service. One was withdrawn in April 1977 and the two others in October 1983.
