In 2008, I helped with the project of renaming CP's on the Pittsburgh Division from numbers to words. When possible, we used the historic names of predecessor railroads. But there were a locations where we had to start from scratch. When nobody proposed a name for the signals at CP64, I wrote down the name of my son - ZACK. Nobody objected. Almost four years later, I was finally able to capture an image of him photographing a train at "his" control point.
