The ALL NEW Atlas Interlock Control Module, (ICM), item # 70 000 047 is set to arrive in initial limited quantities this month. This module adds the advanced capability of “route-based signaling” to the All Scales Signal System. The ICM serves as an interface between Atlas Universal Signal Control Boards and a turnout, reporting the turnout position and setting the proper aspects of all affected signals. More information on complex interlocking track schemes and signal configurations can be found in the signaling documentation on the Atlas website,
