PS 3.0 Enhancements
Here are some of the exciting changes incorporated into your new MTH Proto-
®
Sound 3.0 Locomotives. More advanced features such as Custom Speed Tables and
Advanced Consisting can be found in the DCC section of this manual.
Conventional (Analog) AC/DC Start-up/Shut-down
Your new MTH PS3.0-equipped locomotive no longer has batteries. It uses Super
Capacitors to hold the engine board alive for a short time when you shut off or
interrupt track power. Because of this, when you first apply track power to your
PS3.0-equipped O Gauge engine, you will notice the headlight comes on but nothing
else. This is perfectly normal. The capacitors are charging up during this time. The
wait time depends upon how long it’s been since you last applied power to the
engine. Typically it will take 1-15 seconds to fully charge.
NOTE: The 1-15 second
charging wait time ONLY applies to conventional AC track power.
Once the headlight shuts off, the engine will play its start-up sounds and all the lights
will come back on, simultaneously. Smoke too if you have it turned on.
The capacitors hold enough charge to play the full shut-down sounds. Also, the
capacitors allow you to operate your engine in conventional mode just like you would
any other conventionally-controlled engine. Finally, because there are no batteries,
you will notice there is no external charge jack on the engine.

DCS/DCC Switch
Your MTH PS3.0-equipped engine has a DCS/DCC selector
switch (located on the underside of the tender in steam
engines). To operate the engine in DCS mode, ensure the
switch is set to DCS. If you wish to run the engine in DCC
mode, ensure the switch is set to DCC.
If you inadvertently leave the switch in DCC it won’t hurt
anything, you just won’t be able to communicate with your
engine with your DCS system. Likewise, if you leave the
