Abstract: A power system for a locomotive includes a battery configured to provide electrical power to at least one component of the locomotive, an engine monitor for detecting whether an engine of the locomotive has been shut down, and an automatic power saver operatively associated with the battery. The automatic power saver includes a controller operatively associated with the engine monitor and configured to receive an input signal from the engine monitor, when the engine is shut down, and generate an output signal if the input signal is received. The automatic power saver includes a battery disconnect relay operably connecting the battery to the at least one component of the locomotive and automatically disconnecting the battery from the at least one component of the locomotive in response to expiration of a predetermined time period following receipt of the output signal from the controller.

Abstract: A power system is disclosed. The power system may have a cryogenic tank configured to hold a supply of liquid fuel, and an engine configured to combust gaseous fuel. The power system may also have a coolant circuit configured to cool the engine, and at least one heat exchanger isolated from the coolant circuit and configured to receive a fluid passing through the engine. The power system may further have a first fuel line extending from the cryogenic tank to the at least one heat exchanger, and a second fuel line extending from the at least one heat exchanger to the engine.

Abstract: A method for operating a consist is disclosed. The consist includes a number of locomotives. The method includes selecting a power setting in a lead locomotive of the consist to generate an overall power request by an input device. Thereafter, a controller determines a power setting in each locomotive based on the overall power request. Next, the controller modulates a power output of one or more locomotives according to a difference between a measure of the overall power request and a measure of a combined power output of all locomotives according to the power setting determined by the controller, such that the combined power output matches the overall power request by keeping the power setting, determined by the controller, of each of the one or more locomotives unchanged.

Abstract: A crack detection system for a cylinder head associated with an internal combustion engine of a locomotive is disclosed. The crack detection system comprises: a closed-loop coolant system for cooling the cylinder head; a sensor assembly including a pressure sensor, and a speed sensor; and a controller in communication with the sensor assembly. The controller is configured to monitor a coolant pressure feedback and an engine duty cycle of the internal combustion engine. The controller is further configured to communicate an alert signal indicative of an existence of a crack in the cylinder head when: coolant pressure signals are greater than or equal to a first threshold and less than a second threshold; a pressure decay is calculated greater than a third threshold.

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.

Abstract: A charge receiving system comprises a first charge receiving rail and a second charge receiving rail attached to a roof of a compartment of a locomotive. The first charge receiving rail is disposed at a first angle relative to a center line of the roof in a longitudinal direction of the locomotive and extends beyond a first edge of the roof, and is configured to electrically contact a first charging contact of an external charging unit and electrically connect to a first polarity terminal of one or more batteries. The second charge receiving rail is disposed at a second angle relative to the center line of the roof and extends beyond the first edge of the roof, and is configured to electrically contact a second charging contact of the external charging unit and electrically connect to a second polarity terminal of the one or more batteries.
