Amtrak station map (2013-02-02)
A work in progress: This shows most Amtrak stations by ridership, though there is a significant amount of noise from defunct stations and bus stops that are or were part of the Thruway Bus network.
To me, this mostly underscores how low-frequency service (once daily per direction for many long-distance and corridor trains -- or even just 3x weekly for the Cardinal and Sunset Limited) is a major factor holding back the railroad. Simple lack of connectivity is another glaring problem.
Created with d3.js (d3js.org) -- I'm hoping to turn it into a dynamic web page at some point.
