FIELD: railway transport.
SUBSTANCE: method comprises surveying contact wires by means of a scanner of high spatial resolution made of two CCD-gages shifted one with respect to the other by 0.5 pixel and connected with the computer and GPS-receiver, determining extent of wear of each wire by means of a computer program for processing the results of survey, and preparing a map of sites with marks on the extent of wire wear.
EFFECT: enhanced reliability.
