Tri-Rail is warning commuters that there is a chance trains could be delayed due to maintenance work on its rail corridor through December.
Tie-replacement work will get underway on September 26 and is scheduled through the day after Christmas, Tri-Rail said.
It said there could be delays due to speed restrictions and single-tracking in the segments where the maintenance is taking place.
Tri-Rail urged commuters to download its app or visit its websiteto learn about service announcements.
