AC Sounder-Sound only Decoder for 3-rail AC EMD645 and 645E

MRC Diesel AC Sounder for EMD 645 and 645E:

Easy two-wire hook-up for conventionally controlled 2 or 3-rail O-gauge locomotives(Lionel, MTH, Williams, etc.).

We have often installed these modules in a dummy unit which has power pick-ups for the headlight. Plenty of room in most powered O gauge units as well. Comes with a 1.5" speaker wired to the sound unit.

MSRP is $45.98.
