New this year

This year's biggest changes are inclusion of the entire track map of the Long Island Rail Road. This includes all-new drawings of the Main Line, Montauk Branches and everything out to Greenport, Montauk and everything in between. Detailed freight sidings and operations of the New York & Atlantic are also included this year, plus the Bushwick Lead and the full Bay Ridge Branch.

Every LIRR station, past and present, has been linked to its Wikipedia entry in the same fashion as the subway system's stations were in previous years. Of course, all the latest changes have been incorporated, including more signals, more historical notes, station numbers, and a handful of corrections were added this year. Over 800 hyperlinks were added for readers of the PDF version, and navigation within the PDF version was improved substantially.

Finally, a new PDF-only file of LIRR Extras was included that shows signal details in F, Harold, Dunton, Jay and Hall interlockings.
