Abstract
A train control-system employs beacon transponders along the track to transmit fixed data to a passing train in addition to dynamic data relating to track availability and routing provided by encoded cab signals transmitted in the track. The fixed data includes the location of block boundaries and distances to such boundaries, timetable speed limits, and the distance to a point along the track at which a speed restriction is in effect. This data and other fixed information is integrated with the dynamic data in an on-board computer which determines train control instructions from the received data and displays the instructions to the train crew. The system is capable of enforcing any restrictive instructions that are not obeyed.
