Caption: For those who had had the opportunity to stand on the old steel road bridge in Limehouse during the passage of Goderich Exeter train 431, they know a photo can never do justice to the sight and sound of the train digging into the beginning of the climb up the Niagara Escarpment. Today would be no different, and the amount of haze blurring the background illustrates that. A day of above freezing temperatures has melted a lot of the snow, accumulated over the past few days. The advance signal to CN's Halton subdivision can be seen blurred in the distance.
