M.T.H.ís HO locomotives feature the firmís most sophisticated version
of its highly acclaimed Proto-Sound digital sound and command control
onboard electronics. The Proto-Sound 3.0 system found in M.T.H.ís HO
locomotives includes features not found in other firm's sound systems
and include a command control receiver that can operate with M.T.H.ís
DCS Digital Command System or any manufacturerís DCC system.
The SD70m-2 will feature an all-new Proto-Sound 3.0 feature never before found in HO products; remotely controlled couplers
that do NOT require an operating track section. Long a staple on our O
and One Gauge models, the HO scale Proto-Coupler features a scale
knuckle that can couple with popular scale couplers including Kadee and
McHenry models, yet can be triggered to automatically open anywhere on
the layout using M.T.H.'s DCS system or any DCC controller. When fired
open, the Proto-Sound 3.0 system plays a clunking sound effect to
simulate the sound of the knuckle opening, followed by air release
sounds of the brake lines breaking apart.
Unlike other HO sound-equipped locomotives currently on the
market, M.T.H.ís diesel locomotives include digital sound synched to
locomotive speed for an incredibly realistic operating experience.
Built-in speed control ensures that your engine travels at scale speeds
(1:87) regardless of changes in grade, load or through curves.
M.T.H.'s diesel locomotives are completely compatible with most
16 volt or higher analog DC power supplies. Under analog operation the
user retains direction control, directional lighting, squeaking brakes
and speed control and diesel engine roar.
When operated in command mode using M.T.H.ís DCS Digital Command System
(DCS), operators will have access to hundreds of features and sounds,
including crossing signals, triggerable operating ditch lights and much
