Development of onboard train automatic control system for Korean standard EMU

The automatic/driverless operation, which are important techniques in metro railways, are required to increase safety, reliability, and transport capacity. To satisfy such demands, we must have a system design and testing technique for the railway system operation. These techniques are related to the onboard train control and communication systems which include TCMS (train control and monitoring system), ATO (automatic train operation), ATC (automatic train control), and TWC (train to wayside communication). These sub-systems must be interfacing with not only each other but also the signal system on the ground. We tested the train control system on Seoul subway 7 line that has been developed on the basis of the standardized type EMU for Korean railway systems.
