Mechanicville, NY to Chicago intermodal train CP 939-NS 205 rolls over the frozen Mohawk River with the Conrail heritage unit in charge. The power made a quick turn at Mechanicville after arriving early in the morning on 2-28 and has a long train of double stacks and auto racks. Normally this train runs from Ayer, Ma to Chicago but the long winter has things out of whack as NS plays catch up on the freight back log.
