The study calculates to what extent increasing the permissible wagon collision speed allows for an increase in the permissible error of the braking system. ISSUES OF „TARGET SHOOTING” IN GRAVITATIONAL
1. INTRODUCTION
Marshalling yards are complex technical organisms, and the efficiency of the entire rail transport system largely depends on their operational efficiency. These stations play and will continue to play a fundamental role in organizing freight wagon flows into trains.
In the process of modernizing the Polish railway system, it is necessary – alongside other actions – to fundamentally modernize marshalling yards, due to the need to increase efficiency and safety for both wagons and personnel, as well as to improve the processing efficiency of the wagon flows handled by them. This modernization primarily consists of upgrading track layouts and automating and mechanizing selected, existing marshalling yards where shunting operations will be concentrated.
In certain rare cases, there may also be a need to build new marshalling yards.
The development of block train transport that does not require marshalling, both for bulk cargo and container trains, the increase in the share of four-axle and multi-axle wagons in the total wagon fleet, and the takeover of short-distance and smaller-load shipments by road transport mean that the tasks of marshalling yards are not growing as rapidly as the overall transport tasks of the railway.
However, it would be a mistake to assume that there will be an elimination or radical reduction of rail transport in single wagons or relational groups numbering several or a dozen or so wagons. Simply put, there is, and always will be, an economic need (…)
