Legacy Issue after Accidentally Unplugging

I would try  the reset procedure for your engine with the Lionel  procedure, I'm sure some one on here might be able to tell you the procedure or you can download from Lionel !

Is the wire from the base still attached to the layout? 

Do the red lights on the base flash when you send a command?

BobbyD: yes it is. Well at least it is to the base. I wonder if maybe it got disconnected underneath the fastrack? That is a good question, I will have to look tonight.

Try pressing the reset button on the remote.  With power on and the engine addressed on the remote, press AUX1 then R (the 0 button).  Was the train running when the base was unplugged?

JFC454: No the train was not running nor was the power strip turned on that connects it all to the wall at the time that it happened.

If the train initially started up in conventional then base was not connected to the ground.  If you have a meter, check the continuity between the base and the outer rail of your track.   How do you physically have the brick connected to the track.  If everything checks out and AUX1, R didn't work, try reprogramming the engine.

 

So I unplugged both the 180w Powerhouse brick and the Legacy command and plugged in the base first and then the brick. Now, when I turn on the Legacy command and then the brick, the train turns on (lights up and makes diesel idle noise) but does not run nor respond to any controls on the command pad

What you are describing is the engine still in conventional mode (lights up and idle noise).  If I pull my ground wire from my base and turn on track power, the engine starts up in conventional.  It can't respond to any commands from the base.  As soon as I plug the ground wire back into the base, the engine goes silent and is waiting for commands from the remote.  So, assuming the power cord is plugged into the base, what you are describing sounds like you have no ground connection to your base.  Most likely it is the base to outer track connection that is bad if that is how your base is wired.  I have my base ground connected to the common terminal of my power supply.

Try plugging the base directly to the outlet or a known good grounded extension cord. TMCC/Legacy don't always work well with power strips.

TRNLVR: I do not think it is the power strip. It is a very expensive one and the set up with the #990 Legacy command set has been ok with it since I bought it. Well, until now....

If all you did was unplug stuff to paint the layout, my guess is still the base wire is no longer attached to the common or track.

Since the ground wire on the base connects to the house ground through the common terminal of the layout's power supply, that main power supply needs to be plugged into a good grounded outlet.   I don't know if the base's own power supply is sensitive to ground problems as well.  

Update: Last night I pulled up the track where the base connects and indeed the black wire was disconnected from the outside rail. So now when I address the engine, all functionality works (lights, sounds etc) but it will not move. When I turn the knob up, it makes a buzzing noise internally and get louder as I turn it up but it does not move. I did check to make sure that it is on the track correctly and the pickups are touching the 3rd rail properly, Thanks to all for getting me this far, any other advice? This is getting so frustrating....

BTW: the engine is a Lionel TMCC and has worked perfectly on my layout in the current configuration.

why not try a reset now that it's working should correct the reset of your issues! reset and reprogram the engine!

The "buzzing noise" sounds like the motor is running but it's not making it to the wheels.  Perhaps you have an engine failure, try running the engine in conventional mode with just a transformer.

Also, the exact model of the engine would be useful here.

GunrunnerJohn: It ran fine in conventional mode. Oddly before I accidentally pulled the wire from outside rail, it only had been around the track 2 times and ran flawlessly using the Legacy command set for that run. Maybe 1 minute of run time. It is a Lionel Dash 8 from the 6-21752 Conrail trailer train set. I bought it from someone that never unpackaged it.

I'm at a loss, I think that's one I'd have to see to understand what is happening.  The buzzing noise that gets louder with the throttle screams out motor running and not connected to the wheels.  If the motor that has the odyssey sensor on it is the one slipping, in command mode it would be quite possible the other motor wouldn't get enough power to move the locomotive.  If this has the LionDrive twist-off trucks, the little nub that links the motor to the truck may have come loose, I've seen this several times.

If you disconnect the base wire from the track, does the engine still run in conventional mode?
