Abstract：Elevated urban rail transit lines have been extensively implemented in modern transportation networks owing to their significant advantages，including shorter construction duration，enhanced route adaptability，and reduced capital expenditures. Shaoxing Metro Line 2 Phase I features characteristic long elevated sections，which serve as the research focus of this paper. Through comprehensive investigation of domestic industry practices in operating and maintaining similar long elevated rail sections，and considering the specific conditions of Shaoxing Metro Line 2 Phase I，this study formulates an overall operation and maintenance framework along with detailed implementation pathways.Furthermore，it examines critical aspects including“the configuration of maintenance access routes for elevated long sections”and“existing challenges with engineering vehicle coordinated construction modes and proposed improvements.”The findings provide valuable reference and guidance for the operation and maintenance of equipment in urban rail transit elevated sections.

Key words： rail transit； elevated infrastructure；long elevated section；equipment maintenance; emergency repair
