The white two-story building in the DPL picture shows up in the left edge of the picture I mentioned earlier missing its paint. But it appears to me that the stock pens in that picture aren't the stock pens that exist today. Look at the drawing on page 117 of "Chama-Cumbres" and the photo on page 116. The stock pens don't appear to match. Now add in the scene today, where the stock pens are much closer to the east switch. Could it be that there were three different generations of stock pens there?
