Here's a wider shot of the yard diesels idling, including a few slugs and an old geep in the safety scheme.
While we're on the topic of Nova, I did notice when I was passing by the Corunna plant that the railway there is now operating with two units, including a very similar SW model switcher, likely a sister unit to 2450. The railway also appears to have a genset like the one below operating again. I'm not sure if it's the same unit as this one, shot several years ago. I was driving by quickly and could only steal a glance.
I didn't venture off the old station platform on my trip to the yard, since I was tight for time. I did notice that one crew was already assembling a train on the east side of the Indian Road overpass, as it shunted autoracks into place. I was not able to catch this train as it made its way west to the tunnel, since my time had run out.
Here's another shot of the train being assembled, framed by a line of tank cars and a buffer car at the front of what will likely be a petroleum train headed somewhere east.
All in all, it was a quiet and disappointing morning. But for me, something is better than nothing. I have not been able to venture out in Ottawa for any train watching in a while. Such is life sometimes.
