CBTC maintenance benchmark

How do metro operators organise their maintenance activities? That’s a key question when migrating from legacy systems to new Communication Based Train Control (CBTC) technology.

Société de transport de Montréal (STM) led a study to help guide their own transition. Montréal‘s metro network consists of four lines, all equipped with the same legacy signalling system. STM started a project to migrate one of the lines to CBTC, involving the replacement of interlockings, ATC and ATS. But when preparing for this, STM wanted clarification on how to maintain a CBTC system and about the best share of work between the supplier and the authority.

The purpose of this study is to better understand how other metro operators organise their maintenance activities, and if the migration from legacy systems to CBTC (and more widely to computer-based systems) involves a shift in the share of work.
