2009 Edition (Version 4.4) on sale while supplies last. Versions 4.0 through 4.3 available as custom orders only at full price.
Version 4.4 was released on January 1st, 2009. This is the last "version-numbered" release and is mostly a reprinting from version 4.3 with updates on South Ferry, the #7 extension, some more roster changes and a lot of added detail on East New York Yard. Going forward from here, barring any major infrastructure changes, Tracks of the NYC Subway will go to a yearly release cycle. The 2010 edition will go on-sale just after Thanksgiving 2009. I also plan on having multiple cover pictures (IRT and B-division) and may consider holding a contest during 2009 for the best pictures, with free books to the winners.
