Abstract: In the actual application process, the automatic block sections of normal speed railway lines realize the track vacancy logical detection through the integrated controlling system for sections. When a railway line crosses the railway boundaries of different railway administrations, different treatment methods are adopted due to the consideration of site conditions, cost and maintenance convenience. This paper discusses the problems in and solutions to the track vacancy logical detection at such boundaries through the integrated controlling system for sections. Based on different actual situations, different design schemes are proposed and their advantages and disadvantages are analyzed and corresponding restrictions and protective measures are proposed to ensure the safety of the automatic block sections of normal speed railway lines, which can provide reference for the selection of schemes in actual engineering projects.

Key words: integrated controlling system for sections, track vacancy logical detection, railway boundary of railway administrations, automatic block, normal speed railway
