CCS RA is being safe hardware-software complex of microprocessor-based interlocking system EC-EM/ABTC-EM and provides the control of automation on small-scale, average-scale and large-scale railway stations and neighboring lines with aim to provide the high line traffic-capacity. CCS RA realized the control algorithms and central interlocking of switches and signals as well as devices ABTC-CM on lines during the operation.

ATW RA is intended for providing to station maintenance men the detailed control-diagnostic information about control facilities condition of the interlocking system EC-EM/ABTC-EM

OCD has three channel architecture for monitoring and control of relay of the 1-st class reliability and operates be commands from CSD unit
