Trains 7

April 14, 2012, a train approaches.

A few hundred feet down the track and a half-hour later, another train.  This is an older design.

April 28, 2012, I moved down the tracks about a hundred feet and photographed another train.  Notice that the second engine is the same one as last week.  Also note that the first engine has air horns, but the next two engines have bells.
