Comments on: Chart of the day: NYC subway ridership A slice of lime in the soda Sun, 26 Oct 2014 19:05:02 +0000 hourly 1 By: Nic Fulton Tue, 12 May 2009 01:34:19 +0000 The graphs also get influenced by the potential connections available. The B and D trains have become much more significant, and others less so. J, M and Z lines are not very connected to other parts of Manhattan, although they might have been routed differently in the past. Perhaps a better graph would be the ridership on the lines (normalized since lines change name) rather than specific stops.
