O Gauge Working Dwarf Signal from Lionel.
Dwarf signals are generally used in slow-down areas, such as yards,
sidings and terminals and also as "back-up" signals for trains
going the "wrong way" on main lines.
The dwarf signal is modeled from a type of two-light signal which
finds many uses in real railroading.
Does not require expensive overhead structures and can be convenient-
ly located between close parallel lines of track.
Lights change from green to red when train occupies its block.
Automatically resets to green when train clears its block.
Black plastic contruction.
153C contactor included.
Includes installation instructions.
