Inhaltsangabe

Excerpt from Railway Block Signalling<br/><br/>A considerable portion of this book appeared as a serial in Tim Electrical Engineer during the latter half of 1896. Since then the matter has been revised and considerably extended by the inclusion of descriptions of other apparatus, and by the insertion of examples of the codes used, and the regulations and rules under which signalling is carried out. Railway signalling appears to have now reached a stage at which some departure from the present methods seems probable. The lines upon which changes will be made will, in all probability, result in a greater degree of automatic control than obtains at present. The degree of control is, however, difficult to predict; and, moreover, the degree of such control desirable is a debatable subject. A study of the lines along which developments are proceeding shows at least two marked divisions. In one, the apparatus is entirely auto matic; in the other, the apparatus is so inter-connected with the operations involved in the movement of traffic, as to act as a check upon the actions of the controller of the traffic, for the time being, in such respects as experience shows to be desirable. The first is by far the more ambitious of the two, and adoption of such methods would constitute a revolution in signalling. The second is the most adaptable to present-day methods and apparatus. Which will be the survivor is difficult to indicate, but completely automatic systems admit of none of the selection which is the chief feature in the movement of heavy traffic of mixed character. The subject of signalling in all its branches is a most important one; and it is because of this importance and the difficulty of thoroughly estimating all the requirements in connection with railway signalling without an accurate knowledge of details, that the author has included the codes, regulations, and rules under which the work is carried out.
