QUICK START - BASIC OPERATION The RailKing Doodlebug contains state-of-the art electronics with several built-in automatic features for incredibly realistic operation. Despite these advanced features, the Doodlebug is easy to operate with any compatible standard AC transformer (see the compatibility chart on page 35). All models are controlled by a ProtoSound® DCRU® electronic reverse unit.

system, transformer and engine are operating correctly. This takes approximately 2.2 seconds during which you will hear the engine’s startup sounds begin. In order for ProtoSounds to properly initiate the system check, do not advance the transformer throttle past 10 volts when you first enter RESET, wait for the diesel startup sounds to begin and then slowly turn the transformer throttle to the off position and then back on again to enter the forward phase.
like the Lionel® Railsounds® No. 5906 Bell Button, by simply pushing the button. If you don’t have a separate bell button, the bell can be controlled through your transformer’s whistle button whenever the engine is in NEUTRAL. The bell will never ring continuously in RESET (Remember NEUTRAL is the state between Forward and Reverse).
When the knuckle fires open you will hear the buzzing of the coil energizing and the sound of the air lines coming apart. It can best be described as a CHA-CHUSHHH sound. The coupler doesn’t have to be fired in NEUTRAL. Once the coupler is armed it can be fired in Forward, Neutral or Reverse. However, you may find that the coupler doesn’t open when firing the coupler at high speeds. Reduce the voltage setting on your transformer if this occurs and run your engine at a slower speed before firing the coupler.
time the voltage is reduced from high to low. Some practice may be required to synchronize the playing of the brake sounds with the movement of the engine. It is not uncommon for the engine to stop before the brake sound is completed. Operators will find that by coordinating the movement of the throttle setting from 8 volts to off will allow the engine to maintain its movement while the brake sounds play.
PASSENGER ANNOUNCEMENTS (PFA) ProtoSounds is now equipped with operator controlled passenger station announcements, hereby known as PFA. This easy to use feature plays digitally reproduced passenger station sounds whenever your engine stops at a train station on your layout. No additional wires or modifications are needed on your layout to enjoy these amazing sound effects. The sounds themselves are randomly generated and randomly “shuffled” on the ProtoSounds software chip.
the bell chiming turn on and if you listen carefully you should hear an air release sound after three seconds have passed at which time you can release the bell button. (Note: because the air release sound is hard to hear, we recommend that you count out a full three seconds before releasing the bell button.) The bell will continue to chime, so if you want to turn off the bell ringing, simply press and release the bell button a second time.
ACTIVATING AND TRIGGERING PASSENGER STATION ANNOUNCEMENTS Before PFA can be heard the feature must be activated first. Activation is accomplished by holding down the bell button for three or more seconds as described in the Activating and Triggering The Passenger Station Sounds section found earlier on page 8. Once the feature is activated, PFA will be played the next time the engine enters the neutral position. In order for PFA to begin, power must remain on once the engine enters the neutral position.
message. The arrival message lists the train by name and the track it arrived on (the track is identified as either track 1 or track 2, alternating each time during the current operating session). Immediately Listen For Air Release Sound And Cab Chatter Message following the arrival message, the sound hhee Pssh of the trains’ doors opening can be heard, followed by a conductor’s warning to passengers to “watch your step.
is followed by a public address message that the train on track 1 or 2 (whichever track number the arriving public address message stated) is now boarding. Upon completion of the PA message, two conductor voice highlights randomly begin playing. These conductor voices include “Welcome Aboard” and “Tickets Please”.
TIPS ON USING THE PFA FEATURES PFA is a unique feature of ProtoSounds that is completely controlled by the operator. You decide how, when or if you want to utilize the feature. By reviewing following tips you should find solutions or suggestions to the various operating scenarios you might encounter when using PFA. Tip #1: You can escape the PFA sequence by interrupting the transformer throttle before the first PA arrival message plays in Event 2 (neutral before reverse).
SELF-RECHARGING BATTERY BACKUP SYSTEM ProtoSounds® state-of-the-art design includes a self-recharging battery backup system for improved performance at any speed. The self-recharging battery backup system is automatically turned on or off whenever track power is turned on or off. There are no switches to turn on or off to enjoy the benefits of the automatic battery backup system.
PROTOSOUND® VOLUME ADJUSTMENT RAILKING Your ProtoSound® system has two types of volume adjustment. A manual turn knob on the bottom of the chassis (See Fig. 4 below) allows you to control all the sounds in the system and a remote control “RESET" option (Option # 6), allows you to control the volume level of the engine sounds remotely from the transformer.
USING “RESET" TO PROGRAM PROTOSOUNDS® As mentioned earlier, there are several programmable options in each ProtoSound-equipped engine that can be remotely set from any compatible standard AC transformer equipped with a whistle button. For a list of compatible transformers, see the chart on page 35. This hands-off approach gives you unprecedented control of your railroad empire’s motive power never before seen in model railroading.
times the throttle is advanced by playing back the number of “Clinks" and “Clanks" to confirm the feature you’ve selected. SETTING THE ENGINE VOLUME Of all the sounds that come with each ProtoSound-equipped locomotive, the one most often turned down is that of the engine volume because it is the one sound normally heard whenever the engine is running and is what usually can become tiresome to the ear over prolonged running sessions. The volume adjustment is controlled through RESET Feature 6.
PROGRAMMING FOR A SEPARATE BELL BUTTON CONTROLLER To operate ProtoSounds with a separate bell button controller, like the Lionel® No. 5906 bell button, you will need to wire up Common the controller to your U U U U transformer and track as shown A B C D RED Wire in Fig. 5. Once the button is BLACK Wire wired, ProtoSounds comes preprogrammed to allow you to operate the bell by simply Figure 5: Wiring Up A Bell Button pushing the bell button once. To turn the bell off, push the button again.
Feature 45. (See the section Using RESET To Program ProtoSounds® on page 17). Once in Feature 45, press the whistle button and wait for the module to sound a bell ding(s). Continue pressing the whistle button until the module plays back one ding for option 1 - Squeaking brakes are activated by the bell button.
you are in neutral, you can blow the horn with the transformer whistle button. To reset ProtoSounds to its original factory setting of no horn in neutral, repeat the above procedure but keep pressing the whistle button in Feature 25 until ProtoSounds only dings once instead of twice. Note: When “Horn In Neutral" is set, the bell will only operate with a separate bell button and the horn will not sound in neutral if the transformer throttle setting is over 11 volts.
PROGRAMMING FOR PROTOCOUPLER OPERATION ProtoSounds comes with a RESET feature that allows the operator to remotely turn off the ProtoCoupler functions. This is especially useful when double or triple-heading ProtoSound equipped engines since every engine equipped with a ProtoCoupler will fire when prompted to by the operator. By turning off the ProtoCoupler operation on certain engines, you can fire the couplers open on the other engines without uncoupling the engines from each other.
that the PFA features have been turned off). Simply turn the transformer throttle OFF and then ON again to lock in the new setting. To reset ProtoSounds™ to its original factory setting of Squeaking Brakes and PFA on, repeat the above procedure but keep pressing the whistle button in Feature 28 until ProtoSounds™ only dings once instead of twice.
RESETTING ALL PROTOSOUND® OPTIONS TO FACTORY DEFAULTS ProtoSounds® is equipped with a RESET feature (Feature 18) that resets all programmable options back to their original factory settings. This is a useful feature if you find your engine not operating the way you think it should and don’t want to take the time to check each RESET feature one at a time. To reset all the RESET features back to their original factory settings, enter RESET and go to Feature 18.
REVERSE UNIT LOCK-OUT OPERATION ProtoSound’s unique design eliminates the need for a lock-out switch on the locomotive by allowing the customer to lock the engine into any directional state (forward, neutral or reverse) from the transformer. This will allow users to run the engine on layouts equipped with block signals or stop stations which would normally cycle the engine back into neutral.
NOTE: When locking the engine in the Forward or Reverse positions, the whistle button will blow the horn. But when locking the engine into the NEUTRAL position, the whistle button may turn on or off sounds of the bell, coupler arming or coupler firing depending on the transformer throttle voltage settings prior to the user’s attempt to lock out the engine. Remember, the horn doesn’t’t blow in NEUTRAL (unless you programmed it to do so using Feature 25.
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. L (Lubricate) Figure 6: Lubricating The Locomotive Chassis Use light household oil and follow the lubrication points marked “L" in Fig. 6 above.
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. 7). 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.
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.
TROUBLE SHOOTING PROTOSOUND® PROBLEMS Although ProtoSound® has been designed and engineered for ease of use, some questions may arise during initial operation. The following table should answer most questions. If you find that your problem can’t be resolved with this manual, contact MTH ProtoSound Electronics (7020 Columbia Gateway Drive, Columbia, MD 21046, 410-381-2580) for additional assistance. HORN PROBLEMS REMEDY Your battery may be undercharged or dead. Try The horn seems distorted at low voltages.
COUPLER PROBLEMS REMEDY The power required to fire the coupler open when the engine is on the Fly may be greater than the ProtoSound system is capable of providing. As a The ProtoCoupler wont let the engine uncouple on the Fly. result, you may experience times when the coupler wont fire open. Unfortunately, the only solution is to stop the engine and fire the coupler in Neutral.

The transformer throttle was interrupted too quickly in neutral thus disabling PFA. Leave the throttle on in neutral until after the PFA arrival message plays. ProtoSounds has a built--in random number generator that randomly selects each sound clip to play.
PROTOSOUND RESET FEATURE CHART The following chart lists the available features found in your ProtoSound equipped locomotive. The default settings for each feature as well as the operation sequence of the feature are listed in separate columns. You can reset all features to their original factory settings by accessing Feature 18 in RESET and press and hold the transformer whistle button until you hear a soft, warbled bell sound.
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.
O-31 OPERATION While the RailKing Doodlebug diesel is more than capable of operating on O-31 curves and switches, you may find that certain light freight cars are prone to derailing when being pulled or pushed by the RailKing Doodlebug through O-31 switches. Should this occur, we suggest adding weight to the cars making them heavier and less likely to derail.
