I have a MTH PS1 diesel locomotive that runs very well in forward and reverse, but the sound doesn't work anymore.
I recently replaced the battery with a new J&W 9v BCR specifically for MTH PS1 and PS2 locomotives.
I am using a MTH Z-1000 transformer - and I have tried to reset the controls by throttling the voltage lever from low to high 18 times - then pressing the bell and horn buttons but that hasn't brought the sound back.
What am I doing wrong?

Since the engine is operating forward and backwards in a conventional manner...
I would be inclined to check the volume control/ potentiometer...cycling in clockwise and counterclockwise. If that doesn't help...you will need to trouble shoot the speaker to see if it is functional.
I had that symptom with an MTH PCC car. Turned out to be a bad speaker. Good luck.
Thanks for the tips.
I cycled the volume control screw, and that didnt solve the problem.
I checked the speaker with a multimeter. I get no ohm readings across the speaker terminals other than a "1". The continuity indicator also reads "1".
The meter is OK I checked it out with some other speakers I have on hand - where I was measuring both continuity and resistance.
The speaker is in a really tough location, and I suppose it wont be that easy to replace.
When you did the reset, did you hear the correct combination of clinks and clanks to indicate successful completion? (I don't recall the exact details, but it's in the manual.) The reset procedure is challenging, and if you make the slightest mistake you have to start all over again.

No clicks or clanks. Absolutely no sounds at all.

Kind of a catch-22 - no sound, so no way to know. I've done a few PS-1 resets, and I don't think I've ever done it right on the first try. Or the second...
It's especially challenging with the Z-1000, since it's hard to tell if you're hitting the right voltage range (IIRC, 6 to 10 volts). I used a multimeter to find the various spots on the dial and used a black marker to record where they are.
