The public transit corporation held a press conference on Thursday to address last week's increase in the frequency of metro issues.
"This is very bad news," said the executive director of the STM's metro operations, Dominique Lemay, in reference to the recent stoppages.
Causes of last week's disruptions:
- Computer problems
- Breakdown of metro cars
- Passenger emergency
Lemay said the metro is one of the more reliable systems in the world, and last week was an exception.
He said over the past 15 years, the average number of 20-minute interruptions on the Montreal metro ranged from 8 to 12 incidents per month.
But the installation of a new, more complex control room contributed to seven interruptions in just one week.
Lemay said the service will be putting a new action plan in place to deal help prevent interruptions.
The STM will also be launching new twitter accounts for each of the metro’s four lines to notify users of delays: @stm_verte @stm_orange @stm_jaune @stm_bleue
