Passenger Station Announcements (PSA):
Your engine is equipped with a sound package of passenger station
announcements that you can play when you pull into a passenger station.
Each sequence described below will play as long as it is left on, randomly
generating sounds, but be sure to allow approximately 30 seconds
between the button pushes described below to allow the PSA sufficient
time to run through each sequence.
1. To cue the sound system to play the PSA, quickly but firmly press the Bell
button once followed by 2 quick presses of the Whistle button while the
engine is moving. As soon as you have keyed in this code, you will hear the
announcement for the upcoming stop and the bell will begin to ring.
2. Press the Direction button or drop and advance the throttle once to stop the
engine. This will trigger the first sequence of PSA. The reverse unit is
temporarily disabled so that the train will not move as you use the Direction
button to trigger the sounds, and Proto-Sound 2.0 has disabled operator control
over the Whistle and Bell buttons until the full PSA sequence is complete.
3. After waiting about 30 seconds for that sequence to run, press the Direction
button again to trigger the second sequence of PSA.
4. After about 30 seconds, press the Direction button again to trigger the third
PSA sequence.
5. Again, after allowing about 30 seconds for that sequence to run, press the
Direction button one more time to trigger the fourth and final PSA sequence.
You will know it is the final sequence when you hear the “All Aboard!” call.
The bell will begin to chime and within a few seconds, the engine will start
and move out on its own at the current throttle setting, in the same direction it
was traveling when you began the sequence. Once the bell turns off, the
operator regains control of the transformer’s bell and whistle buttons and can
ring the bell or blow the whistle as usual.
7
RailKing PA AA Diesel Engine
Tips on Using PSA
• You can terminate PSA at anytime by turning off power to the
track for 15 seconds.
• You do not have to be in Forward to use PSA. At the
conclusion of the full sequence, the train will pull away from the
station in whatever direction you were going when you activated
the feature.
• You can use PSA even if you are double-heading with another
engine. If the second engine is not equipped with PSA at all, you
must remember not to leave the throttle at a high voltage level
once you have stopped the engine to run the PSA. Otherwise, the
engine without PSA will begin vibrating on the track as its
motors strain to move the train, since they cannot be
automatically disabled during the PSA cycle. If the second
engine is an original Proto-Sound engine equipped with PSA,
you may choose to disable it when used in double-heading
operations, so you will not experience competing PSA sounds.
To disable PSA in an original Proto-Sound engine, see the
operating instructions for that engine.
• PSA can be triggered from Neutral. It will operate the same as
if triggered while in motion except that, at the conclusion of the
PSA, the engine will depart in the next direction of travel, as
opposed to the direction it was traveling before entering Neutral.

RailKing PA AA Diesel Engine
Proto-Coupler® Operation
This locomotive is equipped with two coil-wound Proto-Couplers for remote
uncoupling action. Because the Proto-Coupler is controlled through the
Proto-Sound 2.0 microprocessor, it does not require an uncoupling track
section or modification to your layout to function. Use the codes listed below
to fire the coupler (also listed on page 5).
Rear Coupler:
To fire the rear coupler, press the Bell button once followed immediately by
three pushes of the Whistle button. The sound of the liftbar and air line
depletion will play, and the knuckle will be released.
Front Coupler:
To fire the front coupler, press the Bell button once followed immediately by
four pushes of the Whistle button. The sound of the liftbar and air line
depletion will play, and the knuckle will be released. Note: If the coupler is
activated, the sounds will play even if the knuckle is already open.
Speed Control:
M.T.H. engines equipped with Proto-Sound 2.0 have speed control
capabilities that allow the engine to maintain a constant speed up and down
grades and around curves, much like an automobile cruise control. You can
add or drop cars on the run, and the engine will maintain the speed you set.
While the engine is programmed to start with the speed control feature
activated, you can opt to turn it off. This means the engine’s speed will fall as
it labors up a hill and increase as it travels downward. It is also affected by
the addition or releasing of cars while on the run. To maintain a constant
speed when speed control is turned off, you need to adjust track voltage
yourself. When speed control is off, the volume will drop to allow for better
low voltage operation. Full volume is restored upon reactivation of speed
control.
To turn speed control on and off, put the engine in neutral, then press the
transformer’s Whistle button one time then immediately press the Bell button
two times. Two horn blasts will indicate that the engine has made the change.
Repeat the 1 whistle, 2 bells code to return it to the other state. You will want
to do this during the initial neutral upon start-up if you ever couple this
engine to another engine that is not equipped with speed control to avoid
damaging the motors in either engine. Each time you shut down the engine
completely, it will automatically turn speed control on.

Maintenance:
Lubrication and Greasing Instructions
The engine should be oiled and greased in order to run properly.
You should regularly oil the engine and pickup rollers to prevent them from
squeaking. Use light household oil and follow the lubrication points marked
“L” in Fig. 2. Do not over oil. Use only a drop or two on each pivot point.
The locomotive’s internal gearing was greased at the factory and should not
need additional grease until after 50 hours of operation or one year, whichever
comes first. Use a lithium based grease and follow the greasing instructions
below.
1. Remove the six Phillips screws from the chassis, as seen in Figure 3, then
lift the body away from the chassis.
2. Remove the truck blocks from the chassis by unscrewing the large Phillips
motor mount screw on the bottom of each truck block, as shown in Figure 3.

3. 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 (see figure 3a).
4. Reassemble the truck and motor, being careful not to pinch the pickup and
ground wires between the truck block and motor mount.
5. Repeat the procedure for the other motor and truck
6. Reassemble the chassis and body, being careful that the wires are not
caught between the body and chassis, as this can lead to a short that may
damage the electronics beyond repair.
It is also a good idea to lubricate the outside truck block idler and drive gears
with grease occasionally. Add grease to the points marked with “G” in Figure

RailKing PA AA Diesel Engine
Cleaning the Wheels, Tires and Track
Periodically check the locomotive wheels and pickups for dirt and buildup,
which can cause poor electrical contact and traction and prematurely wear out
the neoprene traction tires. Wheels and tires can be cleaned using denatured
(not rubbing) alcohol applied with a cotton swab.
Occasional cleaning of the track will also help to ensure good electrical
contact and to prolong the life of your engine’s tires. To clean the track, use a
clean rag and denatured alcohol (not rubbing alcohol). Unplug the transformer
and wipe the rails of the track, turning the rag frequently to ensure that you are
using clean cloth on the rails.
Traction Tire Replacement Instructions
Your locomotive is equipped with two neoprene rubber traction tires on the
rear set of flanged drivers. While these tires are extremely durable, you may
need to replace them at some point.
1. Remove the truck sides from the truck block in order to slip the new tire
over the grooved drive wheel. To do this, remove the screws as shown in Fig.
4.
2. Make sure the old tire has been
completely removed from the groove in
the drive wheel, using a razor blade or
small flathead screwdriver to pry away
any remains.
3. Slip the new tire onto the wheel. You
may find it useful to use two small
flathead screwdrivers to stretch the tire
over the wheel.
4. If you twist the tire while stretching it
over the wheel, you will need to remove and reinstall the tire. Otherwise your
engine will wobble while operating.
5. Make sure the tire is fully seated inside the groove. Use a razor blade to
trim away any excess tire that doesn’t seat itself inside the groove properly.
6. Reassemble the truck sides to the truck blocks.
Replacement Tires are available directly from the M.T.H. Parts Department.

Self-Charging Battery Back-Up
The special NiCad 7-cell 8.4v self-charging battery in this engine improves
performance at any speed. It ensures that power to the sound system will
remain on during directional changes, or when traveling over dirty track or
switches. The self-charging battery system is automatically turned on or off
whenever track power is turned on or off.
Track power (when applied) recharges the battery, which should last for up to
five years. The special NiCad battery is a dry battery that should not leak or
cause any damage to your engine. However, even this special battery will
eventually wear down and need to be replaced. When you notice that your
engine sounds seem distorted or garbled at low voltages or become silent
when power from the transformer is turned off, test the battery to determine
whether it should be recharged or replaced.
• Put the engine in neutral and leave the track voltage at 12 volts for 15
minutes
• If the garbled or distorted sounds are reduced, the battery charge has run
down and can be recharged. Do this by leaving the engine in neutral with
track voltage at 12 volts for 6-7 hours so the battery can fully recharge (if your
engine has a smoke unit, be sure it is turned off). Or you can remove the
battery (as described below) and charge it in any standard slow charge battery
recharger, following the recharger’s directions.
• If the sounds are not improved at the end of the 15 minute test charge, it is
time to replace the battery (see directions below). Contact the M.T.H. Parts
Department (phone: 410-381-2580; e-mail: parts@mth-railking.com; mail:
7020 Columbia Gateway Drive, Columbia MD 21046-1532) for a replacement
battery. A standard 9v alkaline battery can be substituted until your
replacement arrives, but since alkaline batteries cannot be recharged, it will
eventually wear down. Do NOT use a 6-cell 7.2v battery like those found in
most convenience stores.

Sometimes the Cab Chatter sounds
don’t play.
I can’t get the engine to run after I
power up the transformer. It sits still
with the engine sounds running.
The engine won’t lock into forward,
neutral, or reverse.
The sounds seem distorted, especially
when the whistle or bell is activated.
The engine will not leave the initial
neutral setting
The PSA sounds occasionally repeat
themselves.
I get no sounds when the engine shifts
between directions.
After I turn off my transformer, my
engine continues to make sounds
before quitting.
Cab Chatter plays only in neutral.
The engine is locked into the neutral
position. Follow the procedure in the
“Lock into a Direction” section.
Engine speed must be below 10 scale
mph (approx. 10 volts or less in
conventional mode).
Proto-Sound 2.0 volume is set too
high. Turn the volume control knob on
the bottom of the chassis counter-
clockwise to reduce the volume.
Check to be sure the battery is
installed and fully charged. See the
“Self-Charging Battery Back-Up”
section.
The battery may be dead or need to
be charged. See the “Self-Charging
Battery Back-Up” section.
Proto-Sound 2.0 is designed to
continue to sound for a few seconds
after power to the track has been shut
off.
Proto-Sound 2.0 has a built-in random
number generator that randomly
selects each sound clip to play.
Because there are a limited number of
sound clips available in each PSA
sequence, it is probable that some of
these sound clips will be repeated
from time to time.
17
RailKing PA AA Diesel Engine
PSA Remedy
Once in PSA, the engine doesn’t go
into reverse.
When the PSA enters its last
sequence the bell automatically
comes on.
When PSA is enabled, pressing the
whistle and bell buttons has no effect.
I push the direction button but the next
sound clip in the sequence does not
play or the engine does not come out
of PSA after fourth press of the
direction button.
So that PSA effects can be as realistic
as possible, Proto-Sound 2.0
disables the reversing unit
whenever PSA is enabled. This
way the engine remains still at its
stop as the operator cycles
through the PSA sequences.
PSA is programmed to start ringing
the bell at that point. After
approximately 12 rings of the bell, it
will automatically turn off.
Because PSA must control various
effects in each sequence, ProtoSound 2.0 takes control of these
sound effects until you exit PSA.
Each PSA clip must play for approx.
30 seconds before PSA will advance
to the next step in the PSA cycle. Wait
at least 30 seconds in each PSA
sound clip before pressing the
direction button.
Compatibility
This engine will operate on any traditional O-31 or larger O Gauge track
system, including M.T.H.’s RealTrax® or ScaleTrax™ or traditional tubular
track. It is also compatible with most standard AC transformers. (See page 18
