Building a Simple Intermediate Signal System

Let’s take some of the mystery and confusion out of signaling systems. Starting with intermediate signals is an easier first step with good functionally that can be readily expanded. Watch the signals follow a train and automatically change the aspects. My PRR system uses bi-directional (two-way traffic) position light signals with purchased components and does not require programming, switch point position contacts, resistor wheelsets, or any type of block current detection. No need to cut rail gaps or modify the track feeders; the track power wiring and the signal wiring are independent, utilizing reliable infrared detection. The signal heads are highly detailed and built using available kits from a US-based vendor. Construction photographs detail the entire installation process.
