Caption: Warm & wobbly. It's April 20, 2010 and springtime near Minaki, ON in northwestern Ontario, but it's a hot day on the track. The combination of full sun, disturbed ballast, changing of track ties, and the movement of machinery over warm rails has resulted in a series of sun kinks through this curve on CN's Redditt Sub. It was quite the feeling when the rail began to 'snake' under the wheels of the ballast regulator I was in as it rounded the curve in this picturesque rock cut area. Even as I was taking photographs of the initial kinks the rail continued to flex in additional locations. It wouldn't be long before the regulator and a production tamper teamed up to methodically get the track section back to where it was supposed to be. Just another day on the track with a production tie gang. :-)
