Based on the analysis of the technical equipment characteristics and application status of the existing communication signal system of Shenshuo railway, combined with the requirements of Shenshuo Railway Branch Company for the operation time, speed and transportation safety of heavy-duty trains, a set of locomotive intelligent driving communication signal system suitable for Shenshuo railway was developed, which realized the functions of automatic wake-up, automatic shunting, automatic operation and automatic sleep of locomotives. The field operation showed that the system could reduce the manual labor intensity, and improve the locomotive operation level and consistency, as well as the locomotive operation efficiency with lower energy consumption.
