A method is disclosed that includes receiving information from an information source and determining whether the received information has information of a type to be encrypted before transmitting the received information to a second communication device. Based at least in part on the determination, the method may include either encrypting the information of the type to be encrypted, generating encrypted information, and transmitting the received information including the encrypted information from the first communication device to the second communication device; or transmitting the received information from the first communication device to the second communication device unencrypted.

A system is provided for connecting a first hose of a first vehicle and a second hose of a second vehicle. The system may include a frame, a lacing actuator, first and second guides coupled to the frame, a first grasper, and a second grasper. The first guide may collect the first hose based on movement of the frame. The second guide may collect the second hose based on movement of the frame. The first grasper may receive the first hose from the first guide and deliver the first hose to the lacing actuator. The second grasper may receive the second hose from the second guide and deliver the second hose to the lacing actuator. The lacing actuator may position a first coupler of the first hose in engagement with a second coupler of the second hose.

A mobile platform includes a frame, drive wheels, an energy storage device, and an energy interface device. The drive wheels that support the frame propel the mobile platform on rails along a path without contacting other vehicles that travel along the same path in the same direction, in the opposite direction, or while one of the mobile platform or the other vehicle is stationary. The energy storage device is supported by the frame. The energy interface device is configured to transfer energy to and/or from the energy storage device and an offboard energy device.

Provided herein is a workhead assembly (48) for a railway anchor applicator (10) that can have an anchor clipping mechanism (54) can be configured to operably couple to an anchor receiving mechanism (50). The anchor clipping mechanism can have an apply lever (62) configured to be coupled to an actuator (66). The apply lever may include a fulcrum (78) configured couple to a moveable frame (22) of the workhead. The anchor clipping mechanism may include an applicator arm (60) having an elongated body with a first end, a second end at a distal location, and a middle portion between the first end and the second end. The middle portion may be configured to pivotably couple to the apply lever and a guide pin is located on the second end. An apply cam (64) can be configured to couple to the moveable frame. The apply cam can have a slot configured to receive the guide pin.

A system and method that identify a location and/or magnitude of a ground fault in a circuit having a bus that connects battery strings with loads and a ground reference between the loads are provided. Potential of the bus is shifted relative to a ground reference in a first direction. A first impedance in the bus between the battery strings and the ground reference is determined, and the bus is shifted relative to the ground reference in a second direction. A second impedance in the bus between the battery strings and the ground reference is determined. A location and/or severity of a ground fault is determined based on a relationship between the first impedance and the second impedance.

A system and method include measuring input electric current that is input into an electrically controlled valve to change a position of the valve. Output electric current that is output from the valve in response to the input electric current being input into the electrically controlled valve is measured. Position signals are generated using a sensor coupled with the electrically controlled valve that are indicative of the position of the valve. Baseline values associated with the input electric current, the output electric current, and the position signals are calculated. A health state of the valve is determined by comparing the baseline values associated with the input electric current, the output electric current, and the position signals with subsequently measured values associated with the input electric current, the output electric current, and the position signals.

A vehicle power delivery assembly that includes a mast configured to couple with a vehicle such that the mast projects from the vehicle, and a collection arm configured to be coupled with the mast in a location apart from the vehicle to engage an off-board source of electric current that is off-board the vehicle while the vehicle moves along one or more routes. One or more of the mast or the collection arm is formed from at least one inductive support member that provides an integrated inductor of the one or more of the mast or the collection arm through which at least some of the electric current that is received from the off-board source of the electric current is filtered prior to being conducted to the vehicle.

A system is provided that may include a motor, a locking mechanism, an encoder, and a controller. The motor may rotate a shaft to move a door between an open position and a closed position. The locking mechanism may alternate between a locked and an unlocked position. The locking mechanism may retain the door in the closed position responsive to the locking mechanism being in the locked position and may allow the door to move to the open position responsive to the locking mechanism being in the unlocked position. The encoder may be coupled with the motor and may determine one or more of movement, a speed, or a direction the motor moves. The controller may receive output from the encoder indicative of the one or more of the movement, the speed, or the direction the motor moves to determine a position of the locking mechanism.
