PURPOSE:To perform train digital ATC information transmission having a good noise-proof characteristic and free mutual interference with a train detection circuit by executing train detection in which a track circuit is used be means of spectrum spread communication method. CONSTITUTION:This communication device for train control consists of control signal supplying means 2, 4, 5, 7 that output second and third PN codes that differ in kind from a first PN code, and differ with each other in response to digital train control data, and spread and process a train control signal with that PN codes to supply to the side (S) of the starting end of a rail, onboard receiving means (A), 20 that receive a signal from the rail (T), first detecting means 26 that extracts second, third PN codes by demodulating and processing the received signal and detects the second PN code out of them, second detecting means 28 that detects the third PN code, and a train control data generating means 29 wherein train control data are generated with these means. |
