Not very useful, particularly in Northeast

It seems that two of the largest commuter railroads in the country are missing! Wheres New Yorks Metro North and Long Island Railroad? Why are freight lines attributed to Amtrak only just because Amtrak runs a over them?
Labeling track ownership, trackage rights, tonnage volume, yards, major interchange points, abandoned historic routes are some of the data that would to make this app interesting.

(to Developer- there are very detained rail maps of NY, NJ, CT, MA, PA, Metro North, and LIRR available in pdf from state and MTA web sites. Maybe look at these for ideas on what could be included in future updates.)
