Here's a shot of the switcher, hiding behind a collection of spare axles and parts, taken October 2013. The unit is obviously near the end of the line. At first glance, you can see that it is a General Motors SW model. You can make out the GM logo and the Electro-Motive logo on the cab, not to mention the Canadian Auto Workers logo to the side. The locomotive carries the No. 1. And then there's the inscription on the bottom of the hood.
Here's a more recent shot of the switcher, sandwiched in between the old Nova Chemicals 2003 genset locomotive and CN 7516, which is being used for parts. Not much to learn from this photo, which was taken by my brother this past November.
Last December 22, I made my annual visit to the Sarnia area and took some time to snap a few shots around Sarnia Yard. I was lucky enough to have a clear vantage of the engine from an access road near the old CN roundhouse. You can clearly make out the inscription on the hood, which reads "Quality Built Locomotives for the 21st Century." That suggests to me that this was the old switcher that was used at the old GM Diesel plan in London, Ont. That plant, as most rail enthusiasts know, was closed in 2013. Another curious feature on this engine is the style of trucks. They look much older than the trucks I've seen on SW1200s.
Compare the trucks on the engine above with the trucks on this SW1200, which was crossing Front Street in Sarnia in 1993.
The trucks on the GM Diesel switcher remind me of the trucks on this old MLW unit, from CP's Windsor Yard in 1991.
On Aug. 18 last year, I noticed that the trucks resemble some of these trucks that were lying around in front of Lambton Diesel switcher 0176. Does this mean that the old GM Diesel unit has modified trucks or were the trucks replaced? Are they simply just an older model used on early GM diesels? My guess is they are simpler an older model of trucks.
In many ways, the unit looks very similar to an SW1200, but a few of the features, including its trucks, modified smoke stack, hood vents, fuel tank, and sharp slant between the hood and the cab make me think it's an earlier model. Anyone have an idea what model this engine is and where it's from? I'm sure someone with an old Trackside guide can help.
