Service on the line was suspended from February 17, 2006 to March 9, 2006 after the derailment of six Canadian Pacific freight cars on February 17. The freight cars derailed on the Saint-Laurent Railway Bridge used by the train service. This was one of the longest disruptions in train service for the AMT. High winds were a factor in that derailment. In September 2013 CP banned AMT's multilevel coaches from the bridge during high wind conditions (85 km/h or more), deeming them potentially unstable in such conditions. Since then AMT has used only its single-level 700 series coaches on this line.
