In this scientific article, control sensors and devices have been improved based on the method of counting arrows rolling stock railway transport. The microprocessor-controlled unit system simplified to manage traffic between two stations, a self-monitoring, reliable risky scheme has developed. Wiring diagrams existing transport relays updated for uninterruptible power supplies, microprocessor ...

This paper has investigated the technology of forwarding local wagons at railroad technical stations and established need to improve it given extra downtime wagons. The main issue relates considerable combinatorial complexity tasks operational planning. Another problem is that as part conventional approach, planning a station operation considered separately. lack high-quality models for prepara...
