Here’s the seventh NP Mystery Photo in the series is a pair of photos taken moments apart. The solution appears in Mainstreeter issue 2011-1 (30-1). Click the Hi-Res Photo 7s link on the right once to view a larger image, then put your cursor on the lower right corner of the image and click around till the Orange circle appears. Then click the circle to see the detail of largest image. Questions:• What train is it?• What diesel units comprise this locomotive (model and road numbers)?• When was this photo taken?• What is the location?• Who are the three men?• What are the circumstances?Bonus question:• In the photo with only two men, why would the man on the left look so unhappy? Hint: He was a very likeable fellow with a fine personality. It was not like him to be unhappy.I wouldn’t exactly offer a free dinner at a fine steakhouse for the first person (besides Telltale list members) to answer the bonus question correctly, but I’d sure be tempted to make such an offer! The answer entails a subtle fact and a very interesting story. Drop me a line with your thoughts.
