Abstract: The article discusses the implementation of the problem of troubleshooting in 
railway automation systems. A method for stationary demagnetization devices for rail lashes, 
as well as mobile devices for pulsed demagnetization on a platform car, has been developed. 
Developed methods for eliminating impulse noise affecting the operation of the ILSD device. 
Keywords: ILSD, locomotive signaling, locomotive receiving device, magnetic induction, 
body shape, magnetization, turnouts, demagnetization of materials, magnetization reversal, 
magnetic permeability, depth of penetration of an electromagnetic wave, frequency of 
interference signals. 
I. INTRODUCTION 
The leading place in the world is occupied by monitoring the safety of operation of high-
speed rolling stock, improving the management of railway traffic on the basis of means and 
equipment of automation and telemechanics with elements of new technologies. In the 
process of ensuring security in the world, special attention is paid to improving methods and 
devices for troubleshooting in railway automation systems, including factors such as 
magnetization of rail lashes by constant, variable and electromagnetic fields, the total power 
of which exceeds 100 kW [1]. Therefore, it is necessary to create mobile, mobile and 
stationary demagnetization devices in order to eliminate these phenomena that affect the 
reliable operation of automatic locomotive signaling systems (ALS) and an integrated 
locomotive safety device (ILSD) [7]. 
In the Republic of Uzbekistan, measures are being taken to develop the transport industry, 
including the development of railway infrastructure, increasing high-speed rail lines, 
electrifying existing lines and eliminating failures in automation and telemechanics systems. 
The Strategy for the Further Development of the Republic of Uzbekistan for 2017-2021 
shows tasks such as improving the competitiveness of the national economy, an active 
investment policy aimed at solving transport, communication and social infrastructure 
projects, technical and technological renewal of production, and the widespread involvement 
of energy-saving in production technology. The implementation of these problems, in
