You may have heard about the Modular Signal System – it’s been slowly gaining support in the Free-mo modular community for about a decade now. If you haven’t, read on – it’s an exciting new (well, somewhat new) option to bring ABS signalling and more to your model railroad.
The initial Modular Signal System (MSS for short) proposal was put forth by Gregg Fuhriman in the February 2005 issue of RailModel Journal. He’d developed the idea along with others to bring simple signalling capabilites to Free-mo modular meets. Traditional solutions, using pieces such as C/MRI or Loconet-based systems, are impossibly cumbersome to deal with in an infinitely-reconfigurable modular setup with participants coming from all over. What was needed was an acceptably realistic signalling system that was plug-and-play – no reconfiguration required for the myriad of ways their modules could be put together at each meet.
