It is common practice to keep a spare set like these near crossings so that they can be easily replaced in case of a derailment, etc. The crossing angle is often very specific to a location and the lead time to manufacture a new set could be too long to tolerate. I saw a spare set near the crossing of the IC and the CB&Q in East Dubuque, Illinois, rusting away in the weeds, many years ago. Molybdenum alloy steel is often used in these parts.

I've never seen a diamond with this much extra metal around the frogs. There must be a reason for it but I'm at a loss.
