The train virtual coupling system can be considered as an alternative control system introduced for increasing rail line capacity. The separation distance between consecutive trains is theoretically less compared to the other controls. However, the velocity of a following train may fluctuate significantly due to frequent changes of acceleration rate. Moreover, the separation distance between trains may possibly be lower than the minimum safe distance resulting in unsafe situations. In this paper, approaches for controlling the movement of following trains are introduced. The simulated results demonstrate that trains can proceed safely in that the actual separation distance between trains is not less than the critical safe distance. The trains have also to be driven smoothly, in that the following train is catching up the leading train with a constant velocity and has been platooned with the leading train where the velocity and the distance separating it from the leading train has been maintained. The capacity can be controlled by the range of safe distance, which ensures that the gap between trains is in the range of safe distance. In addition, the acceleration and deceleration rates of the train are realistic. The rates are limited to realistic acceleration and braking capabilities.
