Safe Harbor step down transformer and the fact that the schematic looked like the tracks around there: Is it still intact? Is it used by Amtrak? I would have thought they'd have some sort of SCADA system operated from a central location. |

Yes the Harrisburg Power Control Room is kept intact by the local NRHS chapter. Operations were transferred to another location (Wilmington?) 20 or so years ago. I'm not sure who ran the control room, if it was Amtrak exclusively in the later years or a joint authority of Amtrak, Conrail, SEPTA. |

The power director's room is open only by special request through the local NRHS chapter. It was opened for us attending a joint NRHS and Association of Tourist Railroads and Railway Museums conference. In addition to having the room open, also present to explain things were two people who had actually worked there during the Penn Central era. |

I've sent you an email.Just to the right of the Safe Harbor step down station that Will spotted is the larger Safe Harbor step up station. In the middle of the large vertical box representing the 13.2kv ring are inputs labeled 1, 2 and 27. These are the leads from the two Safe Harbor generators and the frequency changer. There was some arbitrary numbering of major components in the generating station and the FC happened to get #27. Safe Harbor Water Power Corporation drawings refer to the step up station as Conestoga Substation. The P4 - P8 transformers to the right of the 13.2kv ring connect to the outgoing 132kv lines. PRR's electric system was controlled by 5 offices: Power Dispatcher -controlled loading of the generators & frequency changers and operation of the 132kv transmission system. Located upstairs at 30th St Phila.. Power Directors -controlled catenary in their region. Located at the NYP service building (moved there from Exchange Place?), 30th St Phila., Baltimore Station, and Harrisburg Station. All of these still exist but are long unused. Amtrak had a photo record of the NEC made in the 80's-90's and it is available at the Library of Congress. As Evan linked to, look at WWW.loc.gov under American Memory, search the Architecture HABS/HAER collection for PA-404-B (30th Dispatcher), NY-5471-A (NYP Service Bldg), PA-404-A (30th Director) and PA-85 (Harrisburg). Baltimore was not documented. When Amtrak built its Wilmington Control Center the original Westinghouse Visicode brand, telephone relay style, remote control from each of the old offices was overlaid with computer based CETC (SCADA). Initially the old offices provided a backup but the relay control is presumably disconnected at the substation end now. Amtrak would appear to have become responsible for the overall ex PRR electric system as the supply stations, transmission lines, the bulk of the catenary and the bulk of the load are theirs. Conrail, SEPTA and NJT would have just paid for a supply of power as part of their trackage rights. SEPTA of course now looks after the catenary on SEPTA only routes and has built one PRR side switching station at Powelton yard. Bill |
