SYSTEM FOR LAYING CABLE COMMUNICATIONS ON THE RUN FOR A BALLAST-FREE RAILWAY TRACK Russian patent published in 2019 - IPC E01B2/00 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction of railways and can be used in the construction of a ballast-free railway. System for laying cable communications includes a route for laying cables for signaling systems and a route for laying communication cables, an integrated security system and a power supply cable. Tracks are made of reinforced concrete trays with lids. Length of the trays is no more than one meter. External profile of the cable path for the signaling system is a rectangular trapezium, and the internal profile is a rectangle. Cable routing for signaling systems is located on the main railway track behind the supports of the contact network. In separate cable trays for the signaling system there are holes for connecting the signaling cable to the floor-standing devices. Route for communication cables, etc., is located in the technological berm and has an external profile in the form of a rectangle. Inside the route for communication cables is divided into 3 compartments by longitudinal partitions.

EFFECT: enhanced functionality is achieved when laying cable networks.
