Getting four hours of sleep is pretty terrible. However, for a lashup like this, I had to get up for it. Thanks to a heads up from a few railfans, I was able to get down to Bayview for it. Terrified of its earlier than expected departure out of Sarnia, I thought I had little chance, however I ended up waiting almost an hour at Bayview. Finally, CN X396 whipped off the Dundas Sub with CN 5366, CSX 706, UP 4837 and 4529. I must say, this was the best lashup I had seen in a long time. Grumpy as a bear going home due to horrible sleep, I made sure I remembered, it was worth it.
