An active fixed block track circuit comprises at least a fixed block section, comprising at least two rails corresponding to each other, each having an isolation connector at two ends thereof and connected to a power supply unit and a traffic signal; a short driving unit, connected to each of the two rails within the fixed block section; and a detection unit, connected to the short driving unit. In this manner, not only the previous rail traffic signal circuit function where no more than one train may be allowed into the same fixed block section is maintained, but also another train approaching from the rear may be prevented from entering the fixed block section when the detection unit at the fixed block section detects an exceptional case happening at a neighboring fixed block section so that the traffic signal unit is switched into a stop traffic signal.

A computer-readable non-transitory storage medium including instructions, which when executed by a computer, cause the computer to carry out the followings: obtaining a railway vehicle movement profile, wherein the railway vehicle movement profile includes a sequence of measured transmitted currents of a transceiver of a track circuit with respect to time; normalizing the railway vehicle movement profile; extracting one or more features from the normalized railway vehicle movement profile; determining a distance of the extracted features with respect to each centroid of a railway vehicle movement profile type determined in a classification process; and assigning the railway vehicle movement profile to the railway vehicle movement profile type with a closest centroid.

A control arrangement for a rail vehicle, having at least one control device which is or can be connected for the purpose of receiving sensor signals, wherein the sensor signals each represent at least one speed, and having at least one bus connection which is used or can be used to connect the control device to a data bus of the rail vehicle for interchanging data. The control device creates a standstill signal on the basis of the sensor signals and transmits the standstill signal onto the data bus. Also disclosed is a standstill determination device which can receive standstill signals via the data bus, wherein the standstill determination device determines, on the basis of standstill signals received via the data bus, whether the rail vehicle is at a standstill. Also disclosed is a rail vehicle and a method for determining a standstill of a rail vehicle.

A system and method are disclosed enabling the use of electromagnetic engines to traverse a wheeled bogie assembly across a plurality of rails. The electromagnetic engines may be used within a rail assembly comprising four rails and a frog assembly. Further, the electromagnetic engines may be used to traverse between a straight path and a turnout path at a non-moving rail switch having a frog assembly. In one aspect, an algorithm for powering various coils is disclosed wherein the algorithm controls the power level to switch tracks connected to the frog assembly.

A system and method for guidance control on a wheeled bogie is disclosed herein. An electromagnetic engine may be coupled to the wheeled bogie such that the electromagnetic engine may generate magnetically attractive forces between the electromagnetic engine and the rail. The generated force may be used to increase traction for braking and climbing operations. Further, the generated force may be used to counteract hunting oscillation. Still further, the generated force may be used to counteract lift generated by the wheeled bogie operating in a turn with cant.

A system for determining a weight status of a railway vehicle. An emitter to emit radio waves. A first detector arranged on the vehicle to detect radio waves and generate a first distance data set. A second detector arranged on the vehicle to detect radio waves and generate a second distance data set. A third detector arranged on the vehicle to detect radio waves and generate a third distance data set. A fourth detector arranged on the vehicle to detect radio waves and generate a fourth distance data set. The first-fourth distance data set indicate a displacement of the vehicle relative at least one of the rails, the railroad and the ground. The first-fourth detector are arranged at different locations on the vehicle. A processing unit to receive the first-fourth distance data set and determine a weight status of the vehicle based at least on the first-fourth distance data set.
