Homemade New York Subway Map

A homemade New York subway map that includes other railroads and is based on the London diagram. Says the designer:

My design goals were to present a simple, clear diagram of all the passenger railroads in the city and just beyond, including all of the subway, PATH, the Newark subway, and the Staten Island Railway, and showing their relation to the Long Island Rail Road, Metro North, New Jersey Transit and Amtrak. I chose to use a very limited set of symbols to portray a very limited set of data, namely just the railroads and stations, station names, waterways. Use of a diagram allows enlarging of tangled areas to show the routings operated, making this more clear than a scale map.
