M.T.H. Premier Bavarian Class 3/6 Express Operator's Manual page 17

Operation of your MTH Proto-Sound 3.0 engine in conventional DC is very similar to
operating a conventional AC engine. As you increase track voltage, engine speed
increases.
As the track voltage is decreased, engine speed is decreased. When track voltage polarity
is reversed using the polarity or direction switch on the power pack, the engine will run
in the opposite direction. The electronics in your MTH Proto-Sound 3.0 locomotive are
designed to slowly change direction without a need to change the throttle, if you so
desire.
Just change the polarity switch on your DC power pack and the engine will gradually
come to a stop and then automatically begin traveling in the opposite direction. The
speed will build up to the same speed that the engine was going in the previous
direction.When power is first applied to the locomotive, the engine's sounds will start
up when the track voltage reaches about 8 VDC. To get your locomotive moving, after
the startup sounds have finished and the locomotive is idling, slowly increase the track
voltage until the locomotive is traveling at the desired speed.
NOTE – If you apply more than 9.0VDC to the engine at start-up the engine will not
move. This is normal. We refer to this as "Anti-Jackrabbit" and this feature prevents
your model from taking off at high track voltages. Simply lower the track voltage down
below 9.0VDC and then back up to get your engine moving. This applies only when
you start up your engine.
DCS - Digital Command System
While the acronyms are close, this is where the similarity ends between DCC and DCS.
Yes they are both digital control systems. However, M.T.H. DCS is not DCC. There are
several proprietary versions of DCC on the market, but DCS is not one of them.
M.T.H.'s DCS System is a proven technology in the O Gauge, One Gauge, and HO
Gauge markets. First the power signal in DCS is not the command signal. Next DCS
employs a fully functional bi-directional communication scheme opening a vast range
of advanced features and yet so simple and intuitive that you can enjoy them. No
programming tracks, bits and bytes, or conversion of binary to hexadecimal numbers
here. To add an engine in DCS, press "ADD ENGINE". After that, if you want to start
your engine just press "START UP" or to turn the smoke unit on or off, just press
"SMOKE". No combination of letters or numbers to remember.
Additional details can be found in the DCS manual that accompanies your DCS system
or on the MTH Web site, www.mthtrains.com With DCS, you can have a whole fleet of
MTH PS 3.0 engines on the rails and they will remain shut down until you command
them to start up.
Your new Bavarian Class S3/6 Steam Locomotive has two new lighting features not
found on any other models.
