A method for indicating a status of a railroad switch is configured for use in un-signaled (dark) territory utilizing vital audio messages. In one embodiment, the method comprises receiving a DTMF signal from a railway vehicle, initializing control of the switch, and triggering the reporting of a correspondence condition through vital relays or other electronic components.

An interlocking device performs route control for trains based on: first operation diagram information as train operation diagram information on a train which runs between stations; second operation diagram information as train operation diagram information on a train which moves in a station yard; and on-track position information on the trains. The interlocking device changes an order of the route control according to whether a predetermined condition is satisfied.

A system, in particular for controlling signal towers in rail traffic, includes at least a plurality of redundant replicants for generating redundant control signals. A voter structure having a plurality of majority voters is also provided. Each majority voter has a respective output and inputs that are connected to the outputs of the plurality of redundant replicants. The voter structure and the plurality of redundant replicants are separated from one another in terms of hardware, the outputs of the plurality of majority voters are connected to the inputs of a discriminator voter and the output of the discriminator voter provides a control signal, in particular for controlling signal towers. The discriminator voter only emits a control signal when the inputs thereof are not at variance.

A collision avoidance system obtains movement indicative data of plural vehicles included in separate vehicle systems. The movement indicative data can be obtained from sensors onboard the vehicles. The system determines an identification of which of the vehicles are included in the separate vehicle systems based on the movement indicative data that are obtained and determines a collision risk between two or more vehicle systems of the separate vehicle systems based on the movement indicative data that are obtained and the identification of which of the vehicles are in the separate vehicle systems. The system automatically changes movement of at least one of the two or more vehicle systems responsive to determining the collision risk.
