Planning for the Pittsburgh Main Line started on scraps of paper over the years. As the ideas poured in, it evolved into a CAD file. Today, the Johnstown area is near the last changes before actual construction begins at that end.
The layout is a double track Conrail continuous mainline with interchanges to the AVR, Union and CSX.
It has a helix under Johnstown that goes down to staging yards. The helix was added to get the necessary clearance between levels.

The Current Layout Plan is an Adobe PDF file and requires Adobe Reader to view.
