Abstract Abstract：Research purposes： In recent years, Automatic Train Operation（ATO）has been applied in Pearl River Delta intercity railway, which has realized automatic control of train operation, and improved system automation degree and transportation efficiency. Since the condition of mainline railways is more complex, there is no clear technical plan of ATO applied in mainline railway. This paper aims to analyze the characteristics of mainline railway and requirements of automatic train operation, so as to apply ATO in CTCS-2 train control system for mainline railway. Research conclusions：（1）The most feasible grade of ATO applied in mainline railway shall be GoA2: semi- automated train operation.（2）The main functions of ATO applied in mainline railway should include automatic driving train, automatic plan adjustment, accurate stopping and train doors protection.（3）Considering characteristics of mainline railway and requirements of existing equipment, the recommended solution of ATO applied in CTCS-2 train control system for mainline railway in actual projects should be the one based on driver’s valuation.（4）The research results can provide some references for ATO applied in train control system of mainline railways.
