Researching trains in Weston Ontario

I am trying to find out about frieght and passenger trains that used to run through Weston, Ontario. Their frequency, size and weight of the engines. I have a couple of pictures that show the numbers 2525 (on the engine) and 374 (on the coal car). I believe they would be either Canadian Pacific or Canadian National. The information could be anywhere from 1856 to 1960.
If anyone has any knowledge of these I would greatly appreciate it.
Thank you.
