The 2020 edition encompases the latest capital improvements, signal changes and track/signal renewal, including the TS-GCT Shuttle reconfiguration, Second Avenue Subway and more signaling details. As with past editions, Grand Central, the Park Avenue tunnels and Penn Station maps are also included.
Yard notes have been changed to reflect fleet changes on all divisions, signal numbers have been updated and notes on ongoing construction projects have been made.
As always, the main thrust of the book are the black & white track maps, showing every station, every track and all yard leads, all with their respective track numbers. The book is now 160 pages in length, spiral-bound in 8 1/2 x 11" format.
Note that the PDF is at lower resolution and is not printable.
