Thanks, Frank. Me, not being a railroader but having a lot of curiosity about things "rail", I appreciate these shots and especially the explanations.....

Why the uneven wear on the near part of the frog? Neat detail on this photo.

The wheel of a railcar & locomotives are beveled to match the contour of the rail, not flat with a flange. The front of the frog has to be flat, then transition to to meet the rail otherwise the wheel would bounce over the high spot trying to get to it's route.

The railroad wheel is beveled to match the contour of the rail, not flat with a flange. The front part of the frog is flat, then transitions into the shape of the rail at the end so when the wheel rolls over the frog on it's route, it doesn't hop over causing damage to the frog, wheel, or even causing a derailment. You can see at about the halfway point on the frog how it changes shape.
