WSOR 1503 pulls a short freight train past the Public Utilities Commission building in Madison. I saw this train on the Isthmus and chased it across the city. At this point the train is moving along at around 40 mph on its way to do some switching in Middleton. I was able to get here in time to set up, but I couldn't get to the Middleton station before it. Any day that I get to chase a train around town is a good day. Today was a good day.
