Hudson River Depths Near Lower Manhattan

In the map below, I included a new shapefile that I got from New York State dealing with Hudson River depths.  It is interesting to see how deep the transit tunnels must be to clear the river floor.  The other New Jersey files I posted the source already from an earlier posting.  Hudson River depths are in meters.  This is only a test and the data should not be used for any type of analysis or construction.  Data may be from 2007.

Lower Manhattan Trackage Map from New York Division Bulletin, January, 1987

This trackage map was drawn by B. Linder showing streetcar trackage below 23 Street and does not shown the tracks of the Third Avenue Railway System.  Although is is not clear on the map, not all trackage was electrified.  In the downtown and lower east side areas, some trackage was never upgraded to electric conduit track from the time of horsecars because some of the routes did not have enough passengers to warrent the upgrade.  Some line management experimented with battery and compressed air cars.  I believe that some of the battery operated cars lasted until the early 1930's but I am not sure.
