More Grand Trunk Pacific Photos -- 1913

I'd really like to be able to give you a description of the exact location of these photos or even better, who's in them... But it's all a mystery! All I know is that they came from my grandfather's album of his days working with the Grand Trunk Pacific Railway in Western Canada in 1913. I never heard of any stories from any family members, so I'm pretty lucky to at least have the album and the diary!
