PRODUCT OVERVIEW
Getting to Know Your M.T.H. HO Locomotive
Key Features
Your new HO Diesel Engine is equipped with the exclusive M.T.H. Proto-
Sound® 3.0 digital sound and control system. In plain English, this means your
locomotive contains state-of-the-art electronics providing realistic digital sounds,
precisely controlled speed in increments of 1 scale mile per hour, and much,
much, more.
Compatibility
The Proto-Sound 3 system is universally compatible with track power and/or
signal combinations including analog DC (regular DC power pack), DCC
(NMRA Digital Command Control), or DCS (MTH Digital Command System).
Simply set your Engine on the rails, apply any one of these power/signal sources,
and move out! The Proto-Sound 3.0 system automatically senses the track
environment and adapts accordingly. No hidden jumpers, switches, magic wands,
or programming required!!! A vast array of realistic operation is automatic when
the Engine is run on analog DC. You can expand access to features in a DCC
environment. Experience the most your new locomotive has to offer in the
simple to use yet powerful world of DCS. To be clear, DCS is NOT a
proprietary version of DCC, as some other manufacturers offer. DCS is a
comprehensive layout control system designed with one primary goal:
make model trains do amazingly realistic things using a simple and
intuitive controller. We put the complexity on the inside, and the fun in
your hands!
Digital Sound
Your Proto-Sound 3 (PS 3) equipped Engine contains over 100 individual
recordings. These recordings are played back dynamically at appropriate times to
create a symphony of realism for your ears. Hear the diesel roar automatically
intensify or lighten when speeding up or slowing down, listen to the sounds of
brakes squeaking and squealing as you come to a stop, or enjoy the random
conversations of railmen working as your model sits at idle. It's all there and it's
incredible.
Your HO diesel includes built-in realistic horn sound effects, including forward
(two blasts) and reverse (three blasts) signalling and crossing signal sounds, all
available with one-touch control from a DCS controller or through any DCC
controller capable of accessing up to F28.

Digital Control
In standard analog DC mode, your model still operates under digital control. The
PS 3 advance speed control system converts track voltage into digital speed
commands. Your model will run smoothly and consistently at any speed
regardless of load, hills, or curves. If you are a DCC user, you'll quickly learn to
appreciate the precision of our speed control and linear speed curve. DCS users
will enjoy the added benefits of controlling speeds in increments of 1 scale mile
per hour displayed on DCS controllers or easily changing acceleration and
deceleration rates independently without any discussion of bits or bytes. To be
clear, DCS is NOT DCC.
Lights
As you read on, you'll notice there are no instructions for replacing light bulbs in
your diesel. That's because there aren't any. We use specially designed and
controlled LEDs to create realistic lighting effects that occur automatically.
Again, NO PROGRAMMING!! Just come to a stop and watch as the headlight
dims automatically in accordance with rule 17. Of course, as you pull away, the
headlight returns to it's fully bright, yet warm, glow. We even included a light in
the cab so the engineers can see to do their jobs!
More…
In analog DC operation, just flip the track polarity or direction switch at any
speed and watch your Engine gradually come to stop, turn on the appropriate
directional lighting, and smoothly accelerate back up to speed. No other HO
locomotive has features like these. There are so many more things to learn and
enjoy about M.T.H. HO Engines, we could write a book. But, that's no fun. So,
if you haven't already done so, flip to the Quick Start Guide and let's run your
new engine!!

Installing Couplers
Your locomotive comes equipped with remotely controllable scale proportioned
operating Proto-Couplers that can be triggered from any DCC controller or the
M.T.H. DCS Digital Command System. Both the front and rear couplers can be
individually triggered. These couplers will not work in conventional operation
with magnetic arms. We have included a set of magnetic arms that can be
installed into the coupler head if desired for aesthetic purposes.
For those who prefer standard mechanical couplers, we've also included a pair
inside your locomotive's box. Follow the steps below to remove the remote
control couplers and install the mechanical couplers in their place.

following the steps below.

Lubrication
Using light machine or household oil, apply a very small amount to all axles
points as shown.
Your gearbox is properly greased at the factory and probably never needs service
however, if you run excessive hours pulling heavy loads, it's a good idea to
remove the 2 screws from the gearbox cover and re-grease using M.T.H. gear
grease or equivalent.

FEATURES AND OPERATION
Now, for the fun stuff! Your new M.T.H. HO Diesel Engine has more features
and operating capabilities than any HO engine ever built by any manufacturer.
We're going to walk you through everything she does in general but, you'll
probably find a few we forgot to mention on your own.
Modes of Operation
There are 3 modes of operation with different levels of features accessible in
each. We refer to them as analog DC, DCC, and DCS. Here's a little more
explanation before we get into the features of each mode.
Analog DC
This is when there is nothing connected to the rails except a conventional DC
power pack. These power packs generally have at least one variable output
controlled by a throttle of some sort and a means of reversing DC polarity on
the track to change the direction of your engine.
DCC or Digital Command Control
DCC is a popular digital command control scheme wherein the track power is
also a digital control signal. That is, using a DCC controller, you can
communicate with multiple engines and have them all moving at different speeds
or moving in opposite directions on the same track at the same time. The
power/command signal remains constant and engines are “commanded” to
perform as desired. M.T.H. is new to DCC but, we recognize it's importance to
many HO operators. So, we loaded our engine with more DCC features easily
accessible to the operator than any HO engine ever built previously. You DCC
guys are in for a real treat!
Please note, when making setting changes in DCS or DCC, such as address,
please wait a minimum of 5 Seconds after removing power to insure the settings
are stored in the engines memory. Reapplying power in less than 5 Seconds may
result in losing the setting changes.

FEATURES AND OPERATION
DCS or Digital Control System
While the acronyms are close, this is about where the similarities between DCS
and DCC end. 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
friend, this is NOT one of them. M.T.H.'s DCS system is proven technology in
the O and One gauge markets and now, we've brought its power and simplicity it
to you.
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, is so simple and intuitive, you can enjoy them! No
programming tracks, bits and bytes, or conversion of binary to hexadecimal
numbers here! To add an engine in DCS, just press “ADD ENGINE.” After
that, If you want to start your engine, just press “START UP” or, to turn the
sound on or off, just press “SOUND.” No combinations of letters or numbers to
remember! We think you're really going to like this!
Please note, when making setting changes in DCS or DCC, such as address,
please wait a minimum of 5 Seconds after removing power to insure the settings
are stored in the engines memory. Reapplying power in less than 5 Seconds may
result in losing the setting changes.

Analog DC
Not much explanation is required here, and that's exactly why you run your trains
this way! Here's the good news, even if you like to keep it simple, your MTH HO
engine is packed with cool sounds, lights, and operating features, that you're going
to love.
Running the Engine
Set the engine on the rails, and apply DC power. Refer to the Set-Up section of
this guide for instructions on how to lubricate the chassis.
As you increase power, at about 6 volts, the lights and sounds will come on.
Keep going on up to about 8 and she'll move out! About 16 volts DC is adequate
for prototypical speeds however, your engine can handle up to 24 volts DC if you
feel the need for speed!
Changing Direction
If you flip the direction (polarity) switch on your power pack while the engine is
moving, it will gradually slow to a stop, and slowly accelerate back up to speed in
the opposite direction. This is an exclusive feature of MTH engines that we're
sure you'll enjoy. You can also change direction the old fashioned way by
reducing throttle until the engine stops, flip the direction switch, and then increase
throttle again. Either way is OK, we just thought a graceful transition from any
speed would be cool.
If you switch track polarity too slowly, the engine may stop abruptly and not
move in the reverse direction. This is normal. There is a feature we call “anti-jack
rabbit” that prevents the engine from taking off at high speeds when high voltage
is applied to the track instantly. Some direction switches have a “dead” spot
where the power is completely off during polarity changes. This can invoke the
anti-jack rabbit feature. The solution is to flip the direction switch more quickly.
Don't worry you won't hurt the engine.
Speed Control
Your engine is equipped with speed control. This feature is always active, even in
analog DC mode. Basically, your engine constantly measures track voltage and
converts this to a digital speed command. You should notice the speed remains
constant up and down grades, around curves, and with varying loads. This is no
accident. You've got the most precise speed control system available today.
M.T.H. HO SD70ACe & SD70M-2 Diesel Engine
12

Sounds
In this mode, sound are pretty much automatic. If you're moving, you'll hear
diesel sounds.
When your sitting at idle, there may be some maintenance done. You could hear
someone calling for help on the radio. Don't worry, all of this and more is just a
normal part of everyday operations.
When your moving at a pretty good clip and you reduce the throttle quickly, you
may hear the brakes squeak and squeal as the engineer applies them. Of course,
they'll stop when the engine does.
If things get too noisy, just locate the sound volume pot under the rear roof
adjust the volume from maximum down to off, whatever suits you. Turn it
counterclockwise to reduce the volume or clockwise to increase it. Refer to page 7
for volume pot location.
Lighting
Now, this is an illuminating section (we couldn't resist). Your model is equipped
with a headlight, marker lights, operating ditch lights, and cab interior light.
The first thing to know about the lighting is there aren't any bulbs. It's all LEDs
so, if you look for a section on how to replace them, you won't find it. You
should never have to.
As with sounds, in analog DC mode, lighting operation is fully automatic.
They're always on and behave appropriately.
The headlight functions under rule 17 and dims when stopped for a time or while
backing up. Of course, just as you begin to move forward, it goes bright to show
the way.
The cab light is always on so the engineer can always see clearly.
M.T.H. HO SD70ACe & SD70M-2 Diesel Engine

DCC Digital Command Control
Now, if your operating in this mode, you may very well know more about DCC
than we do so, we're going to stick to telling you about our engine in this
operating environment. First of all, in DCC mode, we brought all the features of
analog DC along and of course, added to them. Your new engine has more user
features than any DCC engine ever built. Some of them are even ahead of the
world of DCC!!
Running the Engine
Set the engine on the rails, and apply DCC power. Refer to the Set-Up section of
this guide for instructions on how to connect the boiler and tender.
The first thing you will notice is the engine does absolutely nothing! Don't panic.
This is by design. M.T.H. HO engines never do anything in command mode until
told to do so, regardless of what brand DCC controller you use. In this way, you
could have a fleet of M.T.H. HO engines on the rails and they will remain
shutdown until you command them to start up.
F3 Start up/Shut Down
Select engine address 3 (factory default), press the F3 (Start Up/Shut Down) key,
and your engine will start-up. Lights, sounds, ACTION!!! Roll the throttle and
away you go. Our models are compatible with 14, 28, and 128 speed steps. We
strongly recommend 128 because in this mode, speed steps correspond directly to
scale speeds. That is, speed step 10 = 10 smph, speed step 47 = 47 smph, etc.
You get the idea. When your done, press the F3 key again, your engine will shut
down.
To be clear, pressing F3 when the engine is shut down will start it up. Pressing F3
when the engine is started up will shut it down. Pretty clever, eh?
M.T.H. HO SD70ACe & SD70M-2 Diesel Engine
14

Sounds
As in analog DC mode, the default sound arrangement is automatic. So, you can
just run your engine and its sounds will follow the action. But, you operate in
DCC for a reason. You want access to more features, right? Well, depending
upon the capabilities of your DCC controller, you now have access to a range of
sound features including bell, horn, PFA, engine sounds on/off, master volume,
Doppler, and more.
Here's a brief description of commonly used sound features.
F1 Bell
Toggles bell sounds on/off. Listen to the last half ring of the bell when it stops!
F2 Horn
Blows the horn, for as long as it's on. There are several different ending
signatures depending on how long you hold the button down. Check it out!
F3 Start-up/Shut-down
F4 PFA
PFA in MTH lingo stands for passenger and freight announcements. Since your
engine provides freight service, you'll hear freight yard sounds.. PFA is a very
popular sound feature that's a staple in almost all MTH products. We had to give
you this!
There are 4 sound sequences or segments in PFA. You advance through them at
your command. Each segment has a minimum time of ~10 seconds but more
sounds play the longer you listen.
When running the engine, simply press the F4 key to activate PFA. When you
bring the engine to a stop, the arrival sequence will play. You can remain in this
segment as long as you like.
Press F4 again, and advance to disembarking sequence. Again, you can listen to
this sequence as long as you like.
Press F4 again, and advance to the embarking sequence. Again, you can listen to
this sequence as long as you like.
Press F4 again, and advance to the departure sequence. After a short period the
engine will automatically pull out and resume the speed and direction of when
you entered the feature. The bell will ring for a short while and then turn off
automatically.
M.T.H. HO SD70ACe & SD70M-2 Diesel Engine
15

F6 Master Volume
This command cycles through 9 volume settings from off to max. Each press
advances to the next cycle. Unlike the F6 engine sounds command, when the
master volume is set to off, no sounds can be heard.
If your DCC controller has more F functions, you can access even more features.
Check out the complete list in the chart at the end of this section.
Lighting
As with other feature categories, lighting in DCC mode operates just like analog
DC with regard to rule 17, constant brightness and directional behavior. See that
section for details. DCC provides some additional control to suit your
preferences.
F0 Headlight (also toggles Ditch Lights)
Toggles the headlight on/off.
F5 Lights (Ditch and Number Board)
Toggles all lighting on/off, including Marker and Classification LED's. When
on, all lighting behaves automatically as described elsewhere. When F5 is off, all
lighting is off.
Flashing Ditch Lights
Your locomotive is equipped with flashing ditch lights that flash when the horn
is blown. The engine must be moving in order for the lights to flash when the
horn is blown. Prototypically, when one presses the forward or reverse signal the
engine would be sitting still (the signal is to warn anybody on the track that the
locomotive is getting ready to move). Consequently, the ditch lights would not
flash. However, you can trigger the forward and reverse signals to play when the
engine is moving. In that scenario the ditch lights would flash. The ditch lights
will also flash when the crossing signal F12 is activated.

More DCC
Okay, we've walked you through the basic features and functions available in
DCC (F0..F8) but, there is much, much more. In fact, we've filled up functions
F9 through F28. Some controllers are available today that provide easy access to
F9 through F12 however, we don't know of any that allow you to press a button
for F13 through F28. When the DCC controllers expand to include these
functions, your MTH HO engine will be waiting. Here is a list of the F9
through F28 functions present in your engine with a brief description of how
they work.
F9 Forward Signal
Plays 2 short horn toots to signal the engine is moving forward
F10 Reverse Signal
Plays 3 short horn toots to signal the engine is moving in reverse
F11 Coupler Slack
When sitting still, arms the system to play the sound of coupler slack being
pulled out as the engine moves.
F12 Grade Crossing
F13 One-Shot Doppler (On/Off)
F14 Extended Start UP
Plays a longer, more detailed and realistic start up sound sequence.
F15 Extended Shut-down
Plays a longer, more detailed and realistic shut down sound sequence.
F16 Rev Up
Increases the diesel revs. Each press of F15 r uns the revs up another notch.
There are 8 settings.
F17 Rev Down
Decreases the diesel revs. Each press of F16 lowers the diesel revs a notch.
F18 Engine Sounds (On/Off)
F19 Horn Blast
Plays a single short horn blast so you can make up your own signal patterns.
F20 Coupler Close
Plays the sound of 2 couplers crashing together and closing.
F21 Feature Reset
Resets the engine back to factory defaults with the exception of the address.

M.T.H. HO SD70ACe & SD70M-2 Diesel Engine
18
F22..F24 Idle Sounds 1 - 4.
Plays what we call idle recipes 1 through 4. These sound sequences play
randomly when the engine is at idle but if you have these F functions, you can
trigger them whenever you like.
F26 Brake Sounds
Toggles brake sounds between auto and off. They are on by default but you can
turn them off.
F27 Cab Chatter
Toggles random voices between auto and off. They are on by default but you can
turn them off.
F28 Clickety Clack (On/Off)
Toggles the sounds of sustained speed inside a passenger train between auto and
off. This sound is off by default but you can turn it on (auto). Once on, if you
maintain a steady speed of ~30 smph or higher for more than 30 seconds, the
effect automatically turns on.
Please note, when making setting changes in DCS or DCC, such as address,
please wait a minimum of 5 Seconds after removing power to insure the settings
are stored in the engines memory. Reapplying power in less than 5 Seconds may
result in losing the setting changes.

DCS Digital Control System
As you may have gathered by now, DCS is an M.T.H. exclusive Digital Control
System that provides easy access to dozens and dozens of features in our models.
We developed DCS to provide a powerful and advanced model train control
system that was simple and enjoyable to use. We've accomplished that goal. DCS
further expands the features available far beyond that of DCC. After all, in DCC,
we only had a limited number of “F” commands to fill.
As with DCC, we'll leave the detailed “how-to” system explanations to the DCS
system manuals. What you should know are all the cool features your engine has
built-in, waiting for you to experience.
Running the Engine
In DCS, you simply place your engine on the rails, press “ADD ENG” and the
system will scan the track and automatically upload your engine into the
controller. At this point, you can press “START UP”, roll the throttle and pull
out! That's it!
Speed Control
DCS engines are controlled in scale miles per hour (smph) and increments of
one. So, that means if you dial up 10, your engine will smoothly accelerate to 10
smph. There is no need to select a speed step setting, there's only one precise
linear control at scale speeds. See, powerful yet simple.
Sounds
Independent Volume Settings
Using DCS, you independently adjust the bell, horn, engine, and accent sounds
volume. This is like a mixer so you can set up the engine fit your specific tastes
and sense of realism. Oh, they all move relatively up or down with the master
volume settings.
Doppler Loop
You can either press the Doppler button on the remote to activate what we refer
to as “one-shot” Doppler or, using DCS, you can program a Doppler loop that
will peak at the same point on your layout, over and over.
Custom Sounds
You can fire any of 10 individual sound bites pre-loaded into your engine. These
are typically, diesel idling sounds. Each one at the press of a single button. You
can also make voice or other audio recordings and play them back on command
with ease.
