ABSTRACT:
A train operation control apparatus includes a memory for prestoring speed instructions in accordance with the travelled distances of a train and a counter which starts to operate upon train's passing through a predetermined point to count input signals representative of a travel speed of the train. A speed instruction is read out of the memory in response to a content of the counter so that the train follows the speed instruction. Before the operation of the counter is started, a maximum count of the counter is preset so that a minimum speed instruction is read out of the memory at the start of operation, and based on the content thereof a fault of the counter is detected so that a brake instruction is issued to the train.
