Railway traffic control (RTC) equipment are technical devices developed for maintaining the safety of rail vehicle traffic operation, and must satisfy certain requirements related to a specific level of traffic safety and effectiveness. They are designed to ensure operational reliability under the intended application conditions throughout their entire service life. Regardless of their type and kind, however, they must behave in accordance with the assumed functional rules and requirements. This is why periodic tests of their correct operation are so crucial. Functional tests are applied to this end. They are employed in the course of device design and approval for use as well as in equipment operational diagnostics. Previous methods for generating test sets and their processing have been intuitive and often rely on the experience of testers that have been acquired in the course of implementing other tests. Such tests may be incomplete or fail to take into account all studied functions. Therefore, this article presents a proprietary method for generating functional tests covering railway traffic control devices that improve their readiness. The authors describe a test determination procedure algorithm and specify the conditions to be met by a test set and by optimization criteria. The article ends with a computer-based exemplification of the developed functional test generation method.

“…Вважаємо, що при створенні такого локомотива необхідним є застосування енергоефективного тягового електроприводу [26] та накопичувачів енергії у складі енергетичної установки [21,27]. У поєднанні з оптимізацією керуванням системами локомотива та його рухом [20,28] це забезпечить високу енергетичну ефективність локомотива і, відповідно, сприятиме зниженню витрат на паливно-енергетичні ресурси.…”

The paper reviews shunting electric locomotives, the use of which is becoming widespread due to lower costs of fuel and energy resources and a reduction in the impact on the environment. Mathematical models of the movement of a train with a shunting electric locomotive have been developed. A four-axle electric locomotive with a power of 750 kW is proposed for research. A mathematical model of the movement of a train with a ChME3 diesel locomotive has been developed. To compare the costs of fuel and energy resources for freight and transfer operations, simulations of train movement were carried out on sections of the route Kharkiv-Sortuvalny – Merefa and Kharkiv-Sortuvalny – Lyubotyn with different numbers of cars. The simulation was carried out for movement with a shunting electric locomotive and a ChME3 diesel locomotive. It was established that the costs of fuel and energy resources in the case of using a shunting electric locomotive are 2.5-3 times lower compared to a ChME3 diesel locomotive. Based on the obtained results, it is proposed to use dual mode locomotives for the renewal of shunting rolling stock for electrified sections of railways. The locomotive must be equipped with an energy-efficient electric drive and a combined power plant based on a modern diesel engine or other primary energy source in combination with an on-board energy storage system and intelligent management of energy flows in the traction system.

“…With the development of rail transit and high-speed railway, the requirements for its traction powerasynchronous and traction motor are getting higher and higher [1,2]. Owing to the high speed and high working temperature of the asynchronous traction motor, the conductive materials need high hightemperature strength and good electrical conductivity [1][2][3][4].…”

Many attempts were conducted to improve Cu–Cr alloys’ softening temperature, strength, and electrical conductivity. After homogenised treatment at 900°C for 4 h, hot rolled by 80% at 900°C, solid solution treated at 940°C for 2 h, cold rolled by 50%, and aged at 450°C for 1 h, cold rolled by 50%, and aged at 450°C for 0.5 h, the tensile strength, yield strength, microhardness, and electrical conductivity of the fabricated Cu–2Cr–1Zn alloy were 616.7, 540.1 MPa, 176.7 HV, and 71.5% IACS, respectively, with a softening temperature of 530°C. Orowan precipitation strengthening was the primary strengthening mechanism. These findings bring an effective way to improve the strength and softening temperature with a small loss of electrical conductivity.
