A Pennsylvania Railroad Pacific passenger steam locomotive is headed your way. This one, however, is only a model. You'll find it on display in the Ada railroad depot. The 4-6-2 wheel-alignment locomotive was once a familiar site in Ada, as it carried passengers from New York to Chicago in the 1940s and 1950s. Karl A. Roider, Jr., donated this locomotive to depot display. Click for a photo of a real version.
