Abstract: A locomotive propelled by a hybrid power system includes a boost mode of operation accessible on-demand by the operator. When a throttle is set to deliver maximum power from a diesel-electric engine, an operator can select actuators separate from the throttle to request that a control module deliver additional electrical power from batteries. The actuators may be soft keys or a touchscreen on a computer monitor or mechanical switches as part of the locomotive cab. The actuators provide boost notches of additional power beyond the typical eight notches on the throttle at least for transient conditions, and existing locomotives may be easily and inexpensively retrofitted with the actuators.
