There wasn't a lot of change to the system during 2011 other than a few station names and progress on a couple of track and structure renewal projects. The biggest change for the 2012 edition was the complete reconfiguration and resignaling at East 180th St. The Brighton line rebuild is now complete, the Gowanus Canal Culver Viaduct project continues and station renaming continues unabated. CBTC is fully operational on the L and coming soon to the 7. Rolling stock details were stable this year and for once didn't require extensive re-writes as fleets moved hither and yon
