During a recent trip to St. Louis, Missouri, my wife and I used the local light rail line called Metrolink while we were there. We did this because we got tired of trying to find a place to park our car and paying for the parking place. Also, my wife has never ridden on a train before now and she was impressed by Metrolink. When she asked me what made the train run, I pointed out the catenary wire above the tracks and the pantographs on top of each car. I tried to explain how they supplied power to the motors to make the train run. No my wife isn't a railfan but I am trying to corrupt her and turn her into one. Since we were staying in a hotel in Illinois close to the Shiloh-Scott station, that is where we parked our car and purchased our tickets from the ticket vending machine. Both my wife and I were impressed by the fact that an All-Day Pass on Metrolink wasn't outrageously expensive ($7.50). We didn't have enough time to ride the Blue Line to Shrewsbury and back but we did ride the Red Line all of the way from Shiloh-Scott to Lambert Airport. Then we rode the Red Line back into downtown so we could visit the Convention and Visitor's Bureau before we went to some of the popular tourist distractions (detractions?) such as the Gateway Arch.
