A friction shoe includes a backing plate, plural spaced-apart inserts, and a composite body. The backing plate has a top side, an under side, a long axis, and a cross axis that is perpendicular to the long axis. A width of the backing plate along the cross axis is shorter than a length of the backing plate along the long axis. The plural spaced-apart inserts are attached to the under side of the backing plate. The backing plate and plural inserts are integrally made of a metal material. The composite body is attached to the backing plate and at least partially disposed between and around the plural inserts.

A power converter circuit may include a primary (EP) and a secondary (ES) stage. The primary stage may include a first primary winding (Tr1-P) connected in parallel with a first conversion stage (CPP1), and a second primary winding (Tr2-P) similarly connected with a second conversion stage (CPP2). Each of the first and second conversion stages may include a first primary switch (T1, T3) and first auxiliary switching circuit (CAC1, CAC3), and a second primary switch (T2, T4) and second auxiliary switching circuit (CAC2, CAC4). For each conversion stage, the first auxiliary switching circuit and the second auxiliary switching circuit may include a storage circuit (SC1, SC2, SC3, SC4) having a snubber capacitor (Cs1, Cs2, Cs3, Cs4) and diode (Ds1, Ds2. Ds3. Ds4), and a recirculation circuit (RC1, RC2, RC3, RC4) having a recirculation inductor (Lr1, Lr2, Lr3, Lr4), diode (Dr1, Dr2, Dr3, Dr4), and switch (T5, T6, T7,T8). The storage circuit (SC1, SC3) of the first auxiliary switching circuit (CAC1, CAC3) may be connected in parallel with the first primary switch (T1, T3), and the storage circuit (SC2, SC4) of the second auxiliary switching circuit (CAC2, CAC4) may be similarly connected with the second primary switch (T2, T4).

A control system is provided to receive a plurality of vehicle data from sensors in a vehicle communication network. The control system is disposed on a vehicle in a vehicle system and evaluates a plurality of components of the vehicle system with a predictive model associated with the sensor data. The control system may determine a vehicle status based on the predictive model and modify an operational plan or impose an operational restriction through a propulsion system of the vehicle.

A relay assembly is disclosed herein. The relay assembly can include a first relay with a first reset interface to reset an operating state of the first relay and a second relay with a second reset interface to reset an operating state of the second relay. The second relay can be positioned such that the second reset interface opposes the first reset interface of the first relay. The relay assembly can further include a mechanical armature positioned between the first reset interface and the second reset interface. The mechanical armature can be transitionable between a first position, wherein the mechanical armature is spaced apart from the first reset interface and the second reset interface in the first position, and a second position, wherein the mechanical armature engages the first reset interface and the second reset interface in the second position.

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 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.

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.
