Advanced automatic train protection system

Presents a new automatic train protection system. Such messages as the distance to the preceding train or the speed restriction on switches are transmitted to each train instead of the limit speed set for the train. This is done through the rails using digital codes. An on-board processor generates a braking pattern using these messages and the braking performance. And if the speed exceeds the calculated value, the brake is applied. As this system controls the train speed in one step from full speed to stop, it can shorten the train headway. And it can effectively cope with a mixture of trains with different braking performances
