Background. The article substantiates the need for reliable fastening of wheeled equipment on an open railway platform with increasing loads and rolling stock speeds. Materials and methods. The technical means used for fastening wheeled vehicles during transportation and a new design of a device for accelerated fastening of equipment on a railway platform are considered. Results and conclusions. The possibility of increasing the reliability of accelerated fastening of wheeled vehicles on open rolling stock is shown by using elastic multi-turn chain fastenings in combination with lanyards for fastening, allowing them to be used for various wheel sizes. This fastening method is convenient, costeffective and reliable. The use of the proposed design of the brake system will reduce the wear of the friction surfaces of friction pairs, increase the service life by 1.2...1.3 times, compared with standard brakes of bogies of a substation car, and monitoring and diagnostics of the main parameters of railway equipment (systems) ) using sensors and control devices based on the use of modern non-contact measurement methods: laser, infrared, ultrasonic, fiber optic, etc. will improve the reliability of the substation. The use of a non-contact method for recording the profile of discs using a laser sensor and a scanning device will make it possible to obtain information about the parameters of the profile of the working surface of the brake discs of a railway wheel, including analysis of the complete profile of the brake discs and support of a wear database.
