O Gauge 3-Rail Black Dwarf Signal (Single) (DVFLBS301) blocksignal and 3) how reflective theThis O scale Dwarf Block Signal is part of a prototypical system that a provides the ability to have a fully integrated Block Detection system when used in conjunction with detectors. It is designed to be used with either the DFL unit as a Block Signal, or with the Turnout Controllers for Turnouts. To mount the unit, just drill a 1 8" hole in the layout, insert the fibers and then the tubing to the desired depth. The size of this hole will provide a
