I`m running conv. with batteries installed, have Z1000 trans. Using ogauge tubular. I have 3 TMCC engines when I shut them down the sound keeps running until I pick the engine up off the track, then they shut down. 2 Lionels and 1 Atlas with TMCC. I have other Lionels and MTH  with no problems, same track and trans.

Interesting, have never installed a battery for conventional running, Once the track and locomotive are powered up in conventional the battery is there to continue sounds over direction changes when the track has no voltage correct? Is there a time delay in the system? Otherwise it would just see the lack of track power and run the sounds until the battery is dead until you pick it up and break the common connection?

There is indeed a time delay built in, the RS on battery goes through the normal shutdown sequence after a second or two and then goes silent.

Are you hitting aux 5 for shut down? You need to make sure engine has gone down to idle speed/sound then hit aux 5 that puts into shut down sequence, and it should then shut down then turn power off to the track. 

I personally never have installed a battery. I get the effect your suppose to by doing it the way I said, and no battery. The battery is suppose to just let the engine go into shut down once you turn power off.

Thanks everyone for all your helpful comments. I use the battery as someone wrote so there is no interruption between FNR . Also the repeated startup when coming out of neutral with no battery. But i recently removed  a 022 swtch that was derailing a postwar passenger car, and the continued sound issue at least for the time being has stopped. Maybe wired wrong, maybe common neutrals????

When track power is removed, a TMCC or Legacy engine with a battery (or YLB) will continue making sound for about  5-10 seconds, then play the normal "shutdown" sound. There is no interaction between the battery circuit and the track. 

Maybe your switch was wired in such a way that even though your transformer lever was at minus, there was still enough voltage on the track to keep the sound system running.

 

Rudy, could the presence of the battery lower the threshold of required voltage to shutdown?  Obviously, without a battery of any kind, below around 5 volts, the sound cuts out.  Also, with a battery, just a stray leakage voltage might be enough to trigger it.  I didn't have a lot of luck simulating that, but every RS board is somewhat unique due to component tolerances, maybe some have that narrow band of uncertainty?

Just a thought...

Here is my theory, you said you removed an 022 switch and it seemed to cure the problem. If you are using fixed voltage on the switch, which it sounds like you are, it could be the fixed voltage is bleeding from the bulb in the switch to the ground outside rail, providing just enough power to keep the railsounds operating. Are you using the correct 18 volt bulb, or a LED type replacement bulb? Disconnect the fixed voltage plug and see if that fixes the problem.
