Synopsis
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.
