Built by the Pennsylvania Railroad in 1915, ALTO (JK) tower, in Altoona, Pennsylvania, remained in service for the next ninety-seven years, closing in 2012. Over that time it worked under the auspices of four different railroads, the Pennsylvania Railroad (PRR), Penn Central, Conrail and Norfolk Southern and each railroad, in turn, brought something new to the table. It is easy to think of railroad history over the last century to be one of subtraction; infrastructure being removed as a transportation monopoly yielded to competition from air travel and highways. However, for at least its ninety-seven years in service, ALTO’s story was one of adaptation to the ever changing times.
