I have just acquired a MTH RR cantilevered crossing signal and the flashing electronics are caput. Will someone give me a suggestion of where I can purchase an electronic flashing unit to make this thing work? The lamps are LEDS and that's about all I know about it.

I beleive the flasher circut is internal in that unit. have you tried it?
The way this operates is that the LED's blink in pairs of two. The left pair(front & back) on the cantilever blinks with the left pair on the mast. the right pairs do the same, so that they alternate just like the real signal. The flasher is a 555 circuit , and if my memory serves me today
, there should be three wires that go up the mast to the leds. This should be easily adapted to an external crossing signal flasher (either home brewed or commercially obtained). I know that Dallee makes one, and that the flasher circuit diagram is easily found--- just Google "555 flasher circuit" and there will be hundreds(maybe more) hits.
MIKATT1 - Yes the unit is internal, it ain't no more. I need an electrical solution that I can attach under the table or an OEM replacement.
FEC Fan - great just what the response I needed.

I had one of these go bad and the best thing was to either plug so it can signal via track... all lights come on and off. Or unfortunately toss it into the bin...
All the electronic's for this signal are in the flasher base, I believe there are only 2 screws to remove to access it...
