Безопасность производственной деятельности локомотивного депо

The main factors are considered related to influencing the environment and human health of the production activities of a locomotive depot as one of the main structural units of railway transport. It is noted that the variety of technological processes at the locomotive enterprises causes a wide range of negative consequences for the health of employees and the ecology of adjacent residential areas. Industrial emissions from the locomotive depot enterprises are related to the priority ingredient air pollutants. They have a unidirectional effect, which significantly increases the risk to human health. The main technological processes affecting the state of atmospheric air in the depot territory include rheostat testing of locomotives, drying and filling of sand into locomotives, and combustion of organic fuel in the boiler rooms. The main measures to reduce the negative impact of these processes are analyzed from the point of view of the best available technologies. The sources of air pollution in the working premises of locomotive depot enterprises are considered. It is noted that the greatest hazard to the employees of the enterprise is represented by the production areas where welding, gas-cutting and paintwork are carried out. Pollutants entering the environment from these areas lead to disruptions in the functioning of the human respiratory and circulatory systems, causing allergic, work-related and occupational diseases. Measures are proposed to bring the air in the working area to sanitary and hygienic standards. Special attention is paid to the organization of environmental control points in the areas with the largest multi-component emissions, both in the open area of the locomotive depot and in the industrial premises. This will allow to objectively and promptly assess the negative environmental effect, adjust environmental measures and as a result improve the environmental and industrial safety of the activity of this structural subdivision of the railway transport.

Locomotive maintenance facility layout design using systematic layout planning method: Case study of Semarang Poncol locomotive depot

The Locomotive Depot has a maintenance layout with 6 main lines as maintenance lines. The layout of the facilities is also a problem at the Semarang Poncol locomotive depot because only 1 line can effectively carry out maintenance and repairs so this is a disadvantage because of the dense queue of locomotives wishing to be on duty carrying out daily checks or monthly checks. The problem is that these 3 routes are often 2 of which are not maximized properly and are only used as a place to wait for the repair process and 1 route is effective as a place for maintenance. The Systematic Layout Planning method is a method that plans the layout. The aim of arranging facilities is to increase work productivity and optimize the use of facilities such as work areas, machines and labor. One way to design a facility layout is to pay attention to the sequence of processes and the degree of closeness between units in the facility to be designed. Then, to calculate material handling at the Semarang Poncol Locomotive Depot using the systematic layout planning method, the results obtained from calculating material handling costs from the Semarang Poncol Locomotive Depot were Rp. 99,990/meter and for material handling equipment data, forklifts require material handling costs of Rp. 3,759,649 and for the high diesel speed (HSD) pump requires material handling costs of Rp. 84,288. For the proposed space requirements for each department or room, starting from the spare parts warehouse, the distance changes after calculating 0. Then the used spare parts warehouse changes the distance by -4.7, the lubricant warehouse by -0.1 and the fuel tank by +12.1. Space requirements are seen from the process (towards the maintenance route) after calculating the varying space requirements. From the very first lubricant warehouse and workshop, the distance change after calculating -3. Then followed by TPS B3 used lubricant of -1.9. Then the tool space is +1.1. Then the monitoring room is -5.5. Then the backup generator is -1.5. Furthermore, warehouse facilities are -6. Then the KR/staff space is -3.6. Then the TPS B3 filter is -0.3. Then the rotary spoiler is +13.4 and finally the lubricant warehouse II is +6.3 m2. With these calculations, after carrying out various data processing calculations, the proposed calculation using the systematic layout planning method is in accordance with the character of the Semarang Poncol Locomotive Depot as a service workshop owned by PT. Indonesian Railways. The proposal submitted to the Semarang Poncol Locomotive Depot can be used as a reference in designing the layout of the existing facilities at the Semarang Poncol Locomotive Depot in order to shorten the process flow and material flow for the maintenance process.

Investigation of the possibilities of surface hardening of heavily loaded metal elements made of carbon steels for various purposes

The interaction of the wheel and the rail, being the physical basis for the movement of trains, determines not only such important technical and economic indicators of railway transport as the weight of trains and their speed, the reliability and operational life of wheel sets, but also the basis of the foundations of railway operation - the safety of train traffic. Therefore, studies of the problems of interaction of the wheel-rail friction pair are relevant and in demand not only within the framework of a particular wagon or locomotive depot, but also in the country’s railway transport as a whole. In this regard, it is important to note that one of the main and most loaded elements of the undercarriage of locomotives and wagons that directly interact with the rails are railway wheels. An important factor in the development and implementation of new surface hardening technologies is: firstly, rising prices and corresponding costs for the production of metal products for wheels with high energy consumption, secondly, increasing costs for spare parts, maintenance and overhaul of wheel sets; thirdly, the rise in prices for energy carriers and transportation costs for their delivery; traditional heat treatment is almost impossible to achieve.

EVALUATION OF THE INFLUENCE OF RAILWAY TRANSPORT ON THE PROCESS OF INDUCTION OF CHLOROPHYL FLUORESCENCE IN THE LINDEN TREES LEAVES

The paper presents the results of the study of the influence of railway transport on the passing the fluorescence induction of chlorophyll in the leaves of broad-leaved linden (Tilia platyphyllos). The relevance of research is due to the increase in the intensity of the negative impact of transport on the environment, directly on phytocenoses, which causes a violation of physiological processes and leads to the failure of photosynthesis, which is very important for the vital activity of plants. Thus, the aim of the work was to study the influence of railway transport on the induction of chlorophyll fluorescence in the leaves of broad-leaved linden trees, as one link in the overall monitoring of the impact of railway transport on the environment. The passage of IFH in tree leaves was evaluated using the portable device "Floratest". Trees grown on the territory of the Holosiiv Park were used as controls, and trees growing on the territory of the locomotive depot "Ukrzaliznytsia" served as experimental samples. Measurements of chlorophyll fluorescence induction were carried out on leaves growing on the lower tiers of trees. Assessment of the physiological state of linden leaves under the influence of railway transport was carried out according to the main parameters of the Kautsky induction curve. It was established that the IFH indicators, such as F0, Fpl, F st, Fv, F max, in the trees growing on the territory of the locomotive depot exceeded the IFH indicators of the trees from the Holosiiv park, which is explained by the failure of the dynamic balance between the IFH processes and the violation of photosynthetic processes in the trees . According to the comparative analysis of IFH parameters in control and experimental samples of linden tree leaves, it can be concluded that the trees growing on the territory of the locomotive depot "Ukrzaliznytsia" were slightly stressed by possible noise, vibration and chemical pollution caused by the operation of the railway.
