4-6-2 New Style Pacific Overview The new style Pacifics are characterized by the completely new drivetrain, with the "prime mover" gearboxes, all axles driven. Also the plastic siderods were replaced with metal. Mechanically much better. On the bulkhead, there are two switches one over the other. The top switch (viewed looking into the cab) to left is track power, and to right is battery power. (the manual is in error) The bottom switch is the motor on off, to the right (engineers side) is on. The drivers have improved, now better plated: Besides the improvement in the drivetrain, the latest model has the Aristo socket for easy DCC or R/C conversion.
