Re: Narrow Gauge or Standard Gauge?

I know that this forum is primarily about NG and these photos relate to the SG D&RG, but there are some really neat things in the two photos of #524, both apparently taken at Burnham, sometime in the late teens or early 1920's. In the lower picture, which appears to me to have been taken several years before the upper, a number of interesting details stand out. First, and foremost, there is NO crankpin on the main driver, nor an end on the main rod. Looks like the main rod bearing froze to the crankpin and both had to be cut off to allow the locomotive to move. Obviously the crew caught the problem before the rod broke, as there is no collateral damage to the side of the locomotive as would have happened had it broken off while running. The second thing that is interesting, is that in the second photo, the engine has a wood slat pilot, and in the first, it has foot boards, meaning that after the lower photo, it was converted to switching service. It is also interesting to note that the petticoat pipe is laying on the cylinder, meaning that there are plugged flues somewhere.

And last...... WHAT is that TANK engine parked behind the locomotive in the lower photo? Is it one of the Rio Grande's homemade shop goats from their original SG 2-8-0's (which like the first engine above were originally built to NG plans)?.
