Extensions for the CSX Hanover Subdivision route?

[Mikeov1985]

Does anyone know of any extensions or backdating packages that have been or are being created for the CSX Hanover Subdivision route?

With the recent release of Western Maryland, B&O, and Chessie System expansion packs, my interest has peaked on how that line and its surrounding lines may have looked back in the 1950s, 1960s, and 1970s, especially around Hagerstown and Hanover. Extending the route would allow scenarios with B&O, PRR, N&W, and Reading.

Any info is greatly appreciated. Thanks so much!
