QUICK START - BASIC OPERATION The MTH GP38-2 contains state-of-the art electronics with several built-in automatic features for incredibly realistic operation. Despite these advanced features, the GP38-2 is easy to operate with any compatible standard AC transformer (see the compatibility chart on page 33). The GP38-2 model is controlled by a ProtoSound®...
PROTOSOUNDS® INSTRUCTIONS The MTH ProtoSound® digital sound and train control system provides the operator with unprecedented realistic operation on your model railroad. In addition to actual diesel engine, CD-equivalent 16-bit digital sounds, you get the following features: * Built-In ProtoSound® DCRU® Reverse Unit * Authentic Diesel Horn Sound* Authentic Diesel Bell Sound* Squeaking Brake Sound* Freight Yard Sounds* Operating Remote Controlled ProtoCoupler™* Self-Recharging Battery Back- Up System With Automatic Battery Shut-Off* Remotely Controlled Reverse Unit...
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. Interrupting the power too quickly may cause the system to re-enter RESET (signaled by two dings of the bell). Should this happen, wait longer before interrupting the power to enter the Forward phase.
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). Once the bell is turned on, it will continue to ring when the engine is cycled into forward or reverse until you press the bell button or re-enter NEUTRAL and turn the bell off with the whistle button.
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 Lubricate Coupler Rivet in Forward, Neutral or Reverse.
setting requires that a bell button be used to “arm” the brake feature and is explained in more detail in the “Activating Freight Yard Sounds” section found later in this manual. The sound itself is a stored record on the ProtoSounds®...
FREIGHT YARD SOUNDS (FYS) ProtoSounds® comes equipped with operator controlled Freight Yard Sounds, hereby referred to as FYS. This easy to use feature plays digitally reproduced freight yard sounds whenever your engine stops on your layout and is parked in the Neutral position. No additional wires or modifications are needed on your layout to enjoy these amazing sound effects.

carefully, you should hear an air release sound after three seconds have passed. At this time you can release the bell button. (Note: because the air release sound may be difficult 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 THE FREIGHT YARD SOUNDS Before FYS can be heard, the feature must be armed as described on the proceeding pages. Once armed, activating the FYS effects is accomplished by simply interrupting the transformer throttle and parking the engine in the Neutral position with track power remaining on.

B. After entering Neutral, ProtoSounds® will immediately play an air release sound followed approximately 2 seconds later by a radio arrival message (cab chatter). Immediately following the radio arrival Listen For Air Release Sound And Cab Chatter Message message, the sound of freight car doors can be heard opening, followed by the sounds of freight loading and unloading.
Event 5: (Forward) The operator now interrupts the transformer throttle again to enter the next reverse unit phase; Forward. FYS confirms to the operator that it has entered the Forward phase by playing a radio messagne followed by the freight car door closing. Within 2 seconds of the door closing, the locomotive bell begins chiming.

Tip #4: You can utilize FYS even if you are double-heading with another engine regardless of whether the second engine is equipped with an FYS programmed ProtoSound® module. If the second engine isnt equipped with FYS, the only thing to remember is that you not turn up the transformer throttle very high when entering the Reverse phase found in Event 3.
SELF-RECHARGING BATTERY BACKUP ProtoSounds® state-of-the-art design includes a self-recharging battery backup system for improved performance at any speed. The battery ensures that power to the sound system will remain on during directional changes, setting RESET options or when travelling over dirty track and switches. The self-recharging battery backup system is automatically turned on or off whenever track power is turned on or are off.
substituted as a temporary fix, but since alkaline batteries can’t take a charge, it will eventually wear down. Regardless, it should give you a week to a couple of months use while you wait for your replacement ProtoSound® battery to arrive. PROTOSOUND®...
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 33. 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.
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 the controller to your Common transformer and track as shown in Fig. 5. Once the button is RED Wire BLACK Wire wired, ProtoSounds®...
described on page 8. To change the default setting, enter RESET and go to 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.
button until ProtoSounds® sounds two bell dings (signifying that ProtoSounds® has been programmed to sound the horn in neutral). Turn the throttle off and then on again to “Lock-In" your selection. Now, whenever you are in neutral, you can blow the horn with the transformer whistle button.
want to stop at a yard and have both engines playing their FYS sound effects. To In RESET Mode Move The Throttle Push The Whistle Button Up & Down From Until You Hear turn off FYS, enter RESET High Voltage To Low 2 Bell Dings 28 Times and go to Feature 28.
To lock in the setting, simply turn the throttle all the way off and then back on again. To turn the Remote Lockout Control setting back off, go back to Feature 40 and press the whistle button until only one bell ding sounds. To lock in the setting, simply turn the transformer throttle off and then back on again.
REVERSE UNIT LOCK-OUT OPERATION ProtoSounds® 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.

of the horn. QUICKLY TURN THE POWER BACK ON AGAIN. Your engine is now locked into NEUTRAL. NOTE: When locking the engine in the Forward or Reverse positions, the whistle button will blow the whistle. 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.
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 Figure 6: Lubricating The Locomotive Chassis gears, axles and pickup rollers to prevent them from squeaking. Use light household oil and wheel bearing grease and follow the lubrication points marked “L and 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.
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. Replacement tires are available directly from MTH Electric Trains.

O-31 OPERATION While the GP38-2 engine 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 GP38-2 through O-31 switches. Should this occur, we suggest adding weight to the cars making them heavier and less likely to derail.
