Thanks for the diesel origin explanation. I didn't realize that the NGDF turned my second picture sideways, so I will try posting again right side up if the NGDF will allow it (had to trim the vertical dimension to get it in a horizontal position)
It is my understanding that Railway Appliance Research (AL Proudfoot) performed the restoration of 2816 to operating status, so there is another connection to the photo of 2816 on the BIG bridge.
Below are a couple of shots 2816 on a run to Lethbridge, here south of Golden. Maybe not the greatest shots of 2816, but the British Columbia scenery is simply magnificent in my estimation.
Here is 2816 on it's inaugural run to Calgary on a sunnier day
