HARRIS controlled only the western half of the Harrisburg station complex, the other half was operated from STATE, which was ensconsed in a room on the east (south) side of the station building. STATE also operated ROY interlocking at Royalton. It had virtually no view of the trackage it controlled, however. I'm fairly sure it's still operating, but the Reading line freight connection is, I believe, part of the newer, smaller CP-HARRIS.
What a revoltin' development this is! (William Bendix)
