Enola's South End
Situated at the southern end of the Enola Yards, Day Tower was responsible for movements in and out of the sprawling facility, handling traffic off the Atglen and Susquehanna, Columbia and Port Deposit, Columbia Branch, Northern Central, and Cumberland Valley Division. At one time the tower controlled four electrified running tracks that fanned out to the Westbound Relay and Receiving Yards, and the departure end of the Eastbound Hump and Relay Yard. Located in the West Fairview area along the Susquehanna River the tower was situated on the northern side of the State Route 11/15 overpass between the number 2 and 3 tracks into the yard. The eastern most tracks into the terminal, sometimes referred to as the Northern Central or Baltimore Old Line (tracks 3 and 4) were part of the original NC alignment prior to the 1905 opening of Enola and actually provided a bypass along the eastern side of the yard to Rockville West in Marysville. The western tracks (1 and 2) were built as part of the original construction of the Enola facility.
Day Tower, responsible for both yard moves, westbound arrivals and eastbound departures utilized electro-mechanical, electro-pneumatic and and mechanical (armstrong) machines to control switches and signals in the interlocking. To the south (railroad east) the four tracks narrowed to two in order to cross the Conodoguinet Creek until 1964 when a third span was added to relieve the bottleneck in the busy area. South of the creek the railroad enters the town of Lemoyne where the railroad once again split into multiple tracks under the control of Lemo Tower (previously known as J tower). Today this location, referred to as Stell interlocking marks the end of yard limits and beginning of the Enola Branch which is controlled by the NS Harrisburg dispatchers.
While at the time of this post it is unclear how and when Day met it's demise, today all that remains is the foundation north of footings for the 11/15 overpass. Various sources report conflicting information stating it was closed and demolished in the 1970's while other images clearly show the facility still active in the mid-1980's. One report mentioned it was destroyed while in service as a result of a derailment sometime in late 1986/early 1987, which is not hard to believe considering the location of the structure. Today the interlocking has been removed with all tracks under the jurisdiction of the Enola yardmaster utilizing hand operated switches north of Stell Interlocking. Though not as busy as it was in the PRR era, the area still sees coal traffic to PP&L's large Brunner Island Generating Station and a fleet of nocturnal north and southbound trains heading to Baltimore via the C&PD and Northeast Corridor in Perryville MD.
