OPERATING INSTRUCTIONS
Thank you for purchasing the MTH Electric Trains DL-110 locomotive.
This ¼” scale reproduction of the famous DL-110 locomotive measures
over 19” in length and weighs almost 5 pounds. Despite its scale size, the
locomotive is capable of operating on O-42 3-rail track with most
compatible AC transformers (see the chart on page 9 for a complete list of
compatible transformers and wiring instructions) and is completely
compatible with the DL-109 A unit diesel.
The locomotive is equipped with several deluxe features that are simple
and fun to operate. Each feature is described among the following pages
which should be read before the engine is operated. For those of you who
can’t wait to get started, the Quick Start Basic Operating Instructions
found on Pages 3 and 4 should be read so that you understand the basics of
the operating system.

MTH DL-110 Operating Instructions
QUICK START - BASIC OPERATION
The MTH DL-110 B Unit contains state-of-the art electronics with several
built-in automatic features for incredibly realistic operation. The DL-110
B-Unit is easy to operate with your existing MTH DL-109 A unit using any
compatible standard AC transformer (see the compatibility chart on page 7).
All models are equipped with an operating smoke system that should be
primed with smoke fluid before operating. Adding 20 - 25 drops of fluid
through the smoke stack should be
sufficient. If you choose to not prime the
units with fluid, turn the smoke unit
switch located under the trailing truck to
the OFF position. (See Figure 1) This
will prevent any damage from occurring to
the smoke unit when running the engine
without a primed smoke unit. For more
information see the section on page 4 on
Smoke Unit operation.
The DL-110 powered B-Unit is controlled
by a DCRU® electronic reverse unit which unit operates in the same
manner that all reverse units function by using forward, neutral and reverse
states that are entered each time the throttle is turned on and off or by using
the transformer direction switch (if so equipped). Simply plug the B-Unit
wire harness into the existing sockets of the DL-109 A Unit set to allow
Proto-Coupler® equipped engines and directional lighting systems to
function. Once connected, advance the transformer throttle to cycle all A
and B units together from RESET to Forward as explained in the DCRU
section below.
DCRU® REVERSE UNIT
As mentioned in the Basic Operating section, the engine is controlled by a
DCRU® reverse unit that contains the standard forward-neutral-reverse
states found on most reverse units.
However, when power is first applied to
the track, the reverse unit begins in
RESET or what seems like a neutral
state. Power must be interrupted again
to get the locomotive to enter the
forward state. The system will enter
RESET whenever power to the track is

PROTOSMOKE™ UNIT OPERATION
The DL-110 contains a self-powered smoke unit that outputs a steady stream of smoke
through the smoke stack on the roof of the engine. The ON/OFF switch located next to
the power truck must be in the ON position in order for the smoke unit to function. See
Fig. 1 on page 3.
The smoke unit is essentially a small heating element and wick which soaks up and
then “cooks" a mineral oil-based fluid that omits a harmless smoke. The smoke is then
forced out of the stack via a small electric fan which runs at a constant speed. However,
the smoke intensity can be varied by increasing the transformer voltage setting. The
higher the setting, the more intense the smoke output.
For best results, we recommend that you add
20 - 25 drops of ProtoSmoke™, Seuthe, LGB
or LVTS fluid before you run the engine. If
you don’t choose to add the fluid, then the
smoke unit switch should be turned off.
Failure to either add the fluid or turn the
switch off could lead to damage to the smoke
unit heating element and or wicking. Add the
fluid through the smoke stack hole. After
adding the fluid, gently blow into the stack to
eliminate any air bubbles. Do not overfill the
unit as overfilling can cause the fluid to leak
out and coat the interior engine components.
When the smoke output begins to diminish
while running the engine, an additional 20-25
drops of smoke fluid should be added or the

off for three or more seconds. NEUTRAL should be referred to as the
state between Forward and Reverse.
Because the ProtoSound® system or DCRU® reverse unit found in
your powered MTH DL-109 A unit is not directly connected to the
DCRU® unit in your powered DL-110 B-Unit, you must cycle the
power on and off slowly to maintain proper synchronization between
each powered unit’s reverse unit. If the units should become
unsynchronized, simply shut down power for three or more seconds.
Upon repowering, each unit should come up in RESET. If you choose
to operate your existing DL-109 A units in a “locked-out” state, a
lockout switch on the powered DL-110 B-Unit has been provided so
that you can manually “lock-out” the B-Unit in the same direction the
powered A Units are configured.

MTH DL-110 Operating Instructions
smoke unit switch should be turned off. When storing the engine for long periods of time,
you may want to add at least 20 drops of fluid to keep the wick soaked with fluid and
prevent it from drying out. After removing the engine from storage, it is advisable to add
another 25 drops of fluid, letting the wick soak up the fluid for 15 minutes prior to operation.
SMOKE UNIT MAINTENANCE (2 and 3-Rail)
CAUTION: Operating the engine without smoke fluid and with the smoke unit switch in the
ON position can damage your smoke unit wick, causing the wick to become hard, blackened
and unabsorbant around the heating element. When this occurs, it may be difficult for the
wick to soak up the smoke fluid resulting in poor or no smoke output. If that occurs, we
recommend that you inspect and/or replace the wick taking care to not run the engine
without fluid in the future. You can inspect the wick to see if it needs replacement by
removing the smoke unit circuit board from the smoke unit body as seen in Fig.2. After
removing the circuit board screws lift the circuit board away and inspect the wick. If the
wick is darkly discolored and hard, it should be replaced.

OIL & LUBRICATION INSTRUCTIONS
In order for the engine to perform correctly and quietly, it is important that
the chassis be lubricated before operation. Lubrication should include all
truck block bushings and pickup rollers to prevent them from squeaking.
Use light household oil and follow the lubrication points marked “L" in Fig.
3 below.
The locomotive’s internal gearing in both power trucks has been greased at
the factory and shouldn’t need additional grease until after 50 hours of
operation or one year whichever comes first. Grease cannot be added to the
internal gearing until the body is removed from the chassis which is held in
place by four Phillips screws. The screws are located on each end of the
chassis as seen in Fig. 5 on the following page. After removing the screws,
lift the body away from the chassis and lay the body next to the chassis.
Next, remove the truck blocks from the chassis by unscrewing the large
Phillips motor mount screw on the bottom of each truck block (See Fig. 5).
Once the motor mount screw has been removed, pull the motor away from
the truck block and lightly coat the motor worm gear and bronze drive gear

(in the truck block) with grease. Reassemble the truck and motor, being
careful not to pinch the pickup and ground wires between the truck block
and motor mount. Repeat the procedure for the other motor and truck and
then reassemble the chassis to the body. When reassembling the chassis and
body, be very careful that the lighting wire harnesses are not caught
between the body and chassis as this can lead to a short which may damage
the electronic circuit boards beyond repair.
In addition to the truck block internal gearing, it is a good idea to lubricate
the outside truck block “idler" and “drive" gears with grease. Use the
diagram shown in Fig. 4 on page 6 as a guide and add grease to the points
marked with a “G".
Periodically, check the locomotive wheels and pickups for dirt buildup as
this can significantly affect the engine’s ability to perform properly. Dirty
track and dirty wheels can cause both poor electrical contact as well as poor
traction, especially on elevated track sections. Finally, dirt and oil build up
can prematurely wear out the neoprene traction tires.
TRACTION TIRE REPLACEMENT
INSTRUCTIONS
Your locomotive is equipped with two neoprene rubber traction tires on
each power truck. While these tires are extremely durable and long-lasting
there may arise a time where they will need to be replaced. Should this
occur, you will need to remove the trucks and truck sides on the truck block
from the chassis in order to slip the new tire over the grooved drive wheel.
We suggest you follow the disassembly instructions found in the
Body Mount Screws

Lubrication section on the preceding pages to dissemble the chassis and
truck blocks from the body.
Before the new tire can be installed, you must make sure the old tire has
been completely removed from the groove in the drive wheel. Use a razor
blade or small flatblade screwdriver pry away any remains left from the old
tire that may still be in the drive wheel groove. Once the old tire has been
completely removed, slip the new tire onto the wheel. You may find it
useful to use two small flatblade screwdrivers to assist you in stretching the
tire over the wheel. Be careful to avoid twisting the tire when stretching it
over the wheel. If a twist occurs, the tire will have to be removed and
reinstalled or a noticeable wobble in your engine will occur when operating
the locomotive. In addition, it is important to make sure that the tire is
fully seated inside the groove. Any portion of the tire extending out of the
groove can cause the engine to wobble. A razor blade can be used to trim
away any excess tire that doesn’t seat itself inside the groove properly.
Once the new tire(s) are in place, reassemble the truck sides to the truck
blocks and then reassemble the chassis to the body. Replacement tires are
available directly from MTH Electric Trains.
O-42 OPERATION
While the MTH DL-110 B-Unit is more than capable of operating on O-42
curves and switches, you may find that certain light freight cars are prone to
derailing when being pulled or pushed by the MTH DL-110 through O-42
switches. Should this occur, we suggest adding weight to the cars making
them heavier and less likely to derail.

TRANSFORMER WIRING CHART
ProtoSounds® is designed to work with any standard AC transformer that
uses a “Pure Sine-Wave" format. The chart below lists the many Lionel®
compatible transformers, such as the Lionel KW or ZW models. In
addition, the chart details how the terminals on these compatible
transformers should be attached to your layout. The Trainmaster system
from Lionel® (marked with an asterisk below) will not function correctly
with ProtoSounds without disrupting the sound effects. Therefore,
whenever ProtoSounds senses that the Trainmaster system is being used, it
automatically disables ProtoSound’s sound effects. The operator retains
control over the engine, but no sound effects will play.
*ProtoSounds needs over 14 volts of power to work properly. Overloading or using in-line
accessories with this transformer may lower the peak voltage below ProtoSound’s
requirements.
