| AltoonaWorks added 5/2024 - Zoo interlocking is where Amtrak's Harrisburg Line diverges from the Philly/NYC main. It's quite a complex junction still today. Our followers state that ZOO is still manned. James McKee Ridgway Jr. New York Main barely connected to Harrisburg Main anymore. NY-Pittsburgh Subway track only used for wye moves. No freight connection at all. Harrisburg trains come in to 30th Street, change locomotives and/or direction, and proceed to destination… James Miccolis: James McKee Ridgway Jr. Freight connection was removed under Conrail because it wasn't needed any more. Freight from northern NJ uses the former LV and Reading lines to Philly. Freight going west of Philly uses former Reading lines, Freight going south goes via CSX. The goal was to get as much freight off of Amtrak as possible. That's why the 0 track connection at CP Park and the connection at CP Woodbourne were added. I know because I worked on those signal projects and many others. Tim Shanahan shared |

Once a sprawling plant, it controlled the junction of the West Chester branch, the High Line (elevated freight bypass around/over the 30th Street Station complex) and the Greenwich Yard line with the Main Line (Northeast Corridor). Counterpart to ZOO at southern end of 30th St. Station complex." |

We figured it out pretty quick! |
