Mine, too! One of my favorite books (I am into historical technology) is a reprint of a book entitled: "Interborough Rapid Transit" originally published in 1904, and reprinted by The Arno Press, LC number 71-90436. This book provides a number of fascinating photographs and details on the first New York City subway system; there is about 10 pages on the signalling system. > I can go on at any length or depth on this that anyone wants to hear.

I'd love to find out more details, and would like to get some further documentation for my "collection" if you have any sources. ==> Larry Lippman @ Recognition Research Corp., Clarence, New York ---------------- I suggest contacting the Electric Railroaders' Association, in Manhattan, in New York City . They have, or did have, an active publications department, with all kinds of good stuff. Another possibility is the public relations department of the new York City Transit Authority. Try Don Harold, if he still works there. (Say I sent you, but it's been some years now.) The TA used to give out these great 8 x 10 glossies of old subway cars. Another possibility is the New York Public Library on Fifth Avenue at 42nd Street, which has vast specialized collections. When I was a teenager, say 20 years ago [gasp !!!], I spent a lot of time in the New York History sections. They even have special folders on printed material on the subway system, including the predecessor Els. Other possibilities, which I have not explored personally include the New York Historical Society, the Regional Planning Association, the Port Authority and other government agencies. Another great source is old issues of the New York Times. Just look up the topics in the summaries, and then read the issues. Kind of depressing in a way. "Plus ca change, plus ca rest la memo chose.
