This book analyzes and compares two principal methods of organizing train movements: the time interval method and the space interval method, also known as the block system. The first part of the book describes the time interval method, which relies on timetables, train orders, train order signals, and train dispatching. This method has inherent disadvantages that make it less efficient for directing train movements. The second part of the book describes the space interval method, which uses timetables, train orders, train order signals, train dispatching, and the block system. The block system enforces an interval of space between trains moving in the same direction, regardless of the time interval. The author argues that the space interval method is more efficient, safe, and reliable than the time interval method. The book provides a detailed comparison of the two methods, including their operating efficiency, relative safety factors, and relative operating efficiency of the three block systems: manual, controlled manual, and automatic. The author concludes that the space interval method, with its superior simplicity and safety, is the most efficient method for directing train movements.
