My annual purchase of the latest edition of the geekiest book on my shelves arrived today, and I am fully nerded out.

@mattblaze I was today years old when I learned about this wonderful bit of geekery!!! Thanks, Matt!
@mattblaze I did not know this existed. Now I must have it.
I buy this every year because god forbid I might have an out of date guide to every switch and signal on the subway system in a city where I no longer actually reside.
@mattblaze I assume you also have this amazing book?
How much does it change each year?
@alienghic A little (but he added the LIRR this year, so this time there's actually a lot of new material).
@mattblaze Oooooo I don't live in NYC (or, America) but this is right up my geek street. I only wish there was one for London.
