The Class B locomotive is the mainstay of PV&T freight operations. The 89 class B engines in operation handle most of the PV&T's road, switching, and transfer operations. From the delivery of the first class B1 in 1920, the PV&T, ALCO, and GE have been refining the model for better and higher performance.
