Use of Communication-Based Train Control (CBTC) signalling systems continues to expand globally as metros build new lines and modernise existing ones. While CBTC shares many operational principles with traditional fixed-block signalling, it introduces greater reliance on software, data, communications networks, and the integration of multiple subsystems. These differences have significant implications for how organisations manage operations and maintenance activities.
This study examines the operational and maintenance (O&M) structure associated with CBTC implementation and explores how metros can optimise the existing organisation of their O&M teams to adapt to CBTC management.
Drawing on insights from 34 COMET members, the report reviews good practices that metros have implemented to improve their team structures for CBTC, and highlights common challenges encountered during implementation and transition.
