Marklin 03402 - The H0 Signal Book
Complete explanation of signal technology in the prototype and as models. English Language (picture shows German version). Sample applications for semaphore/target and color light signals.
This book is from 2003, so the newest MFX signals are not in this book. I do find it very useful, since it explains where to use the signals, and how to create stop sections.
Presentation and applications of the newer color light signals.
Contents approximately 100 pages.
Format approximately 26.4 x 22 cm / 10-3/8 x 8-11/16 inches
