Programming Track (for DCC operation)
Your MTH Proto-Sound 3.0-equipped locomotive does not program well on
Programming tracks due to the inclusion of super capacitors utilized in the locomotive's
electronic package. The super capacitors provide backup power to the electronics,
allowing the locomotive to better negotiate track sections suffering from poor electrical
conductivity. This ensures that sounds continue to play, the locomotive continues to
move forward and lighting remains lit. During power shutdowns, the super capacitors
provide power to allow the locomotive shutdown sounds to continue playing through
their conclusion. Unfortunately, the super capacitors require that operators ONLY
program engine CV’s using Programming on the Main (PoM).
Loading Engine Firmware
Your new MTH PS3.0-equipped engine affords you the ability to load Engine firmware.
Loader version 2.30 or later will allow you to do this. Please refer to the Loader
program’s instructions for more details. So, as MTH releases new features or updates
you will be able to take full advantage without having to ship your favorite engine
anywhere. All new updates are available on our website. MTH will make announcements
as they are available. Not all updates will apply to all engines.
NOTE: Requires a TIU w/version 4.20 or later firmware, and requires Consumer
Loader version 2.30 or later.
LED Lighting
Gone are the incandescent bulbs. Your new PS3.0-equipped engine has LED lighting.
MTH uses various colored LEDs to simulate the correct lighting on your engines from
the warm, yellow-orange colored light coming out of an old lantern on your favorite
steam engine to the high-intensity halogen lamp on the latest modern diesels, LED's
allow for various, correct colors. Also, they require less power and do not emit as much
heat as incandescent bulbs.

DCS/DCC Switch
Your MTH PS3.0-equipped engine has a
DCS/DCC selector switch located on the
underside of the chassis between the front
trucks. 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 switch in DCS
and try to operate the engine under DCC you
may notice a humming coming from your
engine and you will likely notice that your DCC
system’s overload light will be on.
