Excerpt from The Block System of Signaling on American Railroads: The Methods and Appliances Used in Manual and Automatic Block Signaling The block system is now in use on over 25,000 miles of railroad in America, and it seems likely that this mileage will be steadily increased. Ten years ago, when "American Practice in Block Signaling" was issued, only about one-tenth this number of miles of railroad was worked in this manner; and but few railroad companies appeared to deem block signals necessary. Now, over fifty roads have adopted the system for at least a short length of line, and 27 of them have it in use on over 100 miles each. This fact - that prominent companies all over the country now fully appreciate the value of the space-interval principle, and are putting it in use on their busiest lines - is the most important one to be noted in this revised edition of "American Practice." But the numerous modifications and improvements in electrical and other machinery used in block signaling, which have been made since 1890 are of at least equal interest; and the bulk of the book is, of course, taken up with these. The matter has been entirely rewritten. Nearly or quite every mechanical or electrical device described in the former work has been improved or superseded, and the illustrations now given are all new. Illuminated semaphores have made no progress and are omitted. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from American Practice in Block Signaling: With Descriptions and Drawings of the Different Systems in Use on Railroads in the United States There are practically two systems of block signaling, of which we may call the first the simple block system. Assuming that every railroad is properly supplied with telegraph offices, this may be said to be merely a code of rules by which the attendant at a given station exhibits a signal to hold all trains moving in a certain direction until he receives word by electrical communication that the last preceding [train has reached another station and gone out of the section of track intended to be protected. This is an absolute block system. When the regulations permit a second train to be sent over the road before the first one has gone out of the block section, but under instructions to run slowly, the term permissive blocking is used.
