Signals of German railways


This is a handy little reference book we added to the library about 5 years ago.  Every country has had its own systems, and there has never really been a unified international railway signaling system, beyond the basic horizontal versus diagonal semaphore signal arm and the red, amber and green colors.

This is a smaller format softcover book of 144 pages all printed in color.
