In one embodiment, a propulsion system includes roaming vehicles including a reaction plate installed on a bottom of each of the roaming vehicles, a surface stator matrix installed with a running surface for the roaming vehicles and including single sided linear induction motors (SSLIMs). Each of the SSLIMs include two windings installed orthogonally to one another. The propulsion system also includes motor drives configured to electrically couple to the SSLIMs via a switching panel, and a control system configured to receive information related to the roaming vehicles, receive a desired motion profile for the roaming vehicles across the surface stator matrix, determine which of the SSLIMs to activate and a performance of the SSLIMs based on the desired motion profile, the information, or some combination thereof, and send control signals to the motor drives to control the SSLIMs to produce the motion profile.

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.

An electric supply system for a vehicle system includes two or more electric energy storage devices. Two or more buses each conductively couple an energy storage device with a corresponding load of plural loads. A controller controls conduction of current from one or more of the energy storage devices to one or more other buses to transfer energy to other energy storage devices or other loads. A method includes directing a first energy storage device of a first power supply assembly to supply electric current to a first bus conductively coupling the first energy storage device to one or more first loads onboard the vehicle system. The method further includes conducting the electric current from the first energy storage device to one or more second buses of one or more second power supply assemblies to recharge one or more second energy storage devices or power one or more second loads.
