If you are looking for a good all-around explanation of model railroad signaling, I recently came across this PDF by Richard Johannes: http://www.hubdiv.org/articles/signalsClinic.pdf.
21 lip 2023 · Absolute signals are found at railroad crossings and drawbridges, and at places where trains pass over powered switches, such as at the ends of sidings or at main track crossovers. For two lightly trafficked rail lines in a remote area, stop signs may be sufficient as a type of absolute signal.
By definition, the signaling principles are the underlying principles of a signalling-based safeworking system that are based on the national standards but are independent of the requirements of a specific railway operating company and of the technology used.

This document provides definitions and explanations of key terms used in railway signalling, including: - Service braking distance (D) is the distance needed for a train to brake safely from line speed.
10 maj 2020 · It explains the fundamental principles behind railway signalling systems a generic way that does not focus on specific national solutions.
In the US, signals show engineers the speeds they are allowed to go. This is known as speed control signalling. They do not actually need to know how far ahead the line is clear. The speed they are allowed to do will depend on the type of train the driver is controlling.
