FIELD: transport.
SUBSTANCE: invention relates to railway automatics. Device employs rail lines of block sections with generators and track relays, herewith contacts of the track relays are connected to the first and the second data input units connected to logic devices of the first and the second channels of data processing, herewith outputs of the first logical unit are connected to intermediate colour light signal control relay. Herein every logical device is added with memory elements for storing the current state of the device during its testing, besides, each intermediate colour light signal control module is added with control signals accumulation units, parallel inputs of which are connected to control outputs of the first and the second logical devices, and their subsequent outputs and inputs are interconnected in an integral for the given data processing channel ring, herewith the ring of the first data processing channel is connected to the first input of the comparator circuit, to the second input of which the ring of the second channel of data processing is connected, and the output of the comparator circuit is connected with all data output units.
EFFECT: higher traffic safety.
