premise: The journey turned out to be hellish , you can not dam well sleep , I mean they are comfortable trains , but neither of us got a wink . The train was slow and ambling , been mostly single track , freight trains kept causing delay , so much so that we were 2 hours late when we arrived in Montreal , missing our connection . No fuss or problems though , we simply got the next train for Toronto . What might be true if the freight trains did n't cause a delay ?
hypothesis: They would have been two hours late
