Assessment of the possibility of forming trains weighing 7,100 tons with a mass load at the coal loading station Р
Notice bibliographique
Résumé
The article considers the importance and relevance of the development of heavy and long-distance traffic on the railway network. As world experience shows, the development of heavy and long-distance traffic is an urgent and in-demand measure for the active introduction of innovations in railway transport. Heavy lifting is used in Australia, Brazil, Canada, China, USA, Sweden, Norway, South Africa. The length of the lines where such trains run ranges from 180-200 to 1100-1500 kilometres. In most cases, these are specialized highways. The trains include up to 340 wagons. Back in 2015, Russian Railways developed a program for the development of heavy-duty train traffic. On the network of Russian Railways, the number of trains with an increased mass is constantly increasing. Undoubtedly, the development of heavy and long-component traffic has a great positive impact on the activities of the railway industry: the use of innovative wagons with increased axial load, acceleration of the turnover of wagons, increase in throughput and processing capacity of railway facilities, etc. However, like any solution, there are also a number of tasks that need to be solved when considering the organization of heavy traffic on the road network. In particular, the development of heavy traffic requires a systematic approach to the problems of interaction between the crew and the track, wheel and rail, the longitudinal dynamics of trains, overloads in the power supply system, the reliability of providing locomotives during departure, taking into account the length of station tracks and industrial enterprises, and a number of other issues. The article considers the possibility of forming trains weighing 7,100 with a mass load. Calculations of the sufficiency of the length of the tracks of station P, as well as station Z, for the formation of a long-composite train are performed. It has been established that the most appropriate option is to form a train on the tracks of the Z station. Since due to the formation of high-mass trains on two tracks at station P, downtime will increase, there are also shortcomings in the technology of working with heavy trains at this station. The possibility of sending a train weighing 7,100 tons under the condition of starting from the place was checked. There are recommendations on the design of the contact network on the P-Z stage, as well as the organization of a car maintenance point at the Z station. An economic assessment of the feasibility of forming a long-component train has been carried out.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
