Hi All.....
Has any encountered the following?
I was running my MTH 20-20093-1 Rock Island ES44AC PS3 diesel pulling a fairly long string of freight cars. The engine was running well without issues....then I experienced a "minor" derailment. The 7A circuit breaker immediately "popped" and power was cut to that block of track.
After fixing the derailment, I reset the circuit breaker, did an engine "Start Up" thru the remote and continued running the train.
But.....when I pressed S01 on the MTH remote to blow the diesel horn once, it blew twice? Hmmmm....weird! I pressed S01 once again and the horn blew twice again. I pressed SFS on the remote once and that horn sequence blew twice. I pressed SRS on the remote once and that horn sequence blew twice! Uh-oh.....
I tried doing a Feature Reset for that engine, but the remote displayed the dreaded "Out of RF Range" message.....then the engine RESET (I know it reset because the sound volume increased to Maximum and the Smoke unit came on)! After starting the engine, all horn functions still sounded twice. I tried doing a Factory Reset, but the remote displayed the "Out of RF Range" message again and the remote locked up for several minutes; the engine never reset.
After doing a Remote reset and a TIU factory reset, I tried to "add" the engine. The remote displayed the message "No Engine on Track", but then added the engine! 
To aid in determining if this was an Engine issue or TIU issue, I tried and successfully added a different MTH engine and it added without any issues. This other engine ran without any problems and all sound functions worked properly. I also was able to Feature and Factory reset this engine without any "Out of RF Range" messages; it successfully reset both ways.
Note that The ES44AC diesel DOES respond to Start Up and Shut Down commands and does run well when varying speed.
Has anyone encountered such a weird set of symptoms? Any thoughts or input on this weird problem would be greatly appreciated!
