Whole lotta unit trains. CN 120 (Toronto-Halifax stack train) is eastbound through Southwark Yard on the south shot of Montreal, with Montreal's downtown skyline and Mount-Royal in the background. On the left is CN 710, a crude oil train that is parked in the yard till a new crew arrives. At right is a string of TankTrain cars filled with refined fuel which will head west towards Maitland, Ontario at some point in the near future. CN 120 has an incredible lashup consisting of two SD60F's leading an Illinois Central SD70 (CN 5558, CN 5538 & IC 1007).
