Welcome MRH Readers!

Block Detection - A Brief Introduction

Block detectors sense the presence of a locomotive or other rolling stock on a section of track.  They are used as inputs to signal systems and control panels, and to indicate occupancy on hidden track and staging yards.  Our easy-to-install DCC Block Detector senses the current drawn by a locomotive, lighted car, or resistor equipped wheel set.  Simply run the track feeder wire through the hole in the current sensor - no electrical connection to the track is required.  Connect the output, provide power, and adjust the sensitivity - now you're ready to go!  An advanced digital design makes sensitivity adjustment easy and reliable for years of trouble-free operation.

Signals Made Easy

Looking for an easy way to add Automatic Block Signaling (ABS) to your layout?  Involved in Free-Mo or another modular group and want to add signals to your module?  The Modular Signal System (MSS) is the answer.  Defined as a plug-and-play signal system, MSS allows you to add realistic signaling with no programming required!  Our cost-effective MSS modules come complete with everything you need: block detectors (DCC and optical), pre-programmed control logic, LED signal drivers, and a rugged and reliable MSS bus interface.
