keep trains safe and on schedule. It safely tightens up the spacing between trains so that Metro Line and Capital Line trains can share the same tracks between Health Sciences/Jubilee station and Churchill station. Edmonton Transit runs peak-time trains every 5 minutes through downtown, but this frequency could have been increased to every 2.5 minutes when the Metro Line originally intended to be operational. This goal was abandoned by the city after August 2021, having restored 5 minute frequency on the Capital Line. The Metro Line continues to operate on a 15-minute frequency.
