This book provides a detailed run-through of the calculation of a headway. This difficult topic is covered in detail, with a discussion on different types of signals and how this affects a headway. Stations and their effect on headway are also covered, and the effect of a station on a headway can be major. Thoe formulas are presented to complete the calculations needed to understand how headways can be calculated for almost any situation. Tilt trains are a solution to getting trains faster, and this book details many of tyhe key equations to describe how fast a til train can go. In many parts of the world tilt trains have allowed big reductions in travel times, but how is it done? This book details how fast tilt trains can go. Speed is often a critical factor in many rail systems. But how is it determined for any rail system. It is of course the lowest permissible speed for many of the different constraints placed on a rail system by its infrastructure, but what are they? Curves both horizontal, and cant, all play a role. The equations that explain and describe the typical limitations on the speed on a rail system are in this book.This book provides a detailed run-through of the calculation of a headway.
