Where did this tie plate come from?

[ComputerWhiz]

I found a railroad tie plate many years ago in the garden of my new house. I've always wondered where it came from, but I have no idea how to read the information printed on it. What does this diagram of the information tell you about it?

For the information I can tell, it's a piece of a CN rail. I can't quite tell, but I think that the 195 part might be a date where the final number has been removed over time. As I said, it's quite rusty.

Anything you can tell me about this section of track would be great. I live in Southern Ontario (in Canada) if that helps narrow your search at all.

CNR is almost certainly Canadian National Rwy. 

1 or 2 shoulders ('ribs') on the top ?  How far apart ?  

The 115 is almost certainly for 115 lb. RE section rail, with a base width of 5-1/2", which should be the distance between the shoulders (+1/8" or so).  The 100 may be for a similar 100 lb. rail section, or something similar.  100 lb. ARA Type A rail also has a 5-1/2" base. 

Overall dimensions and a description of the spike hole pattern would be helpful, too.

Thanks for the reply.

It is a double shoulder plate with four spike holes (two on each shoulder). The plate is symetrical quarters.

The plate is 7.5"x11" with a 5.5" gap between the sholders. It is not very thick. It's only 0.6" think and the sholders are raise about 0.4" higher than the rest of the plate.

I have one of the spikes because the plate was still attached to the tie in my garden (the other was likely lost when the track workers uprooted the track for removal).

Could the H-Z in the corner actually be HW?  I ask because tie plates that were "hot worked," meaning punched, slotted and sheared at a high temperature versus low carbon steel. The hot worked tie plates were to be marked HZ.  

Plates are to be marked with the tie plate section designation, name or brand of manufacture, the last two digits of the year of manufacture, and if applicable "HW."
