Caption: One week only. Due to emergency work being performed on Autoroute 138 in Montreal this week, Candiac-line trains had extra cars added, and even one train consisting entirely of multilevel cars. These cars have not been in use on this line since 2013, when the Comet cars came back from refurbishing. Today was the last day that the multilevel consist was in use. Here it deadheads back to the South Shore during the morning rush hour as it crosses the St. Lawrence River.
