RAILKING SW-8 DIESEL ENGINE OPERATOR’S MANUAL Compatibility This engine will operate on any traditional O-27 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 pages 46 and 47 for a complete list of...
BEFORE YOU BEGIN: By visiting the M.T.H. website, www.mthtrains.com, you will be able to view any additional manual updates that affect your engine. Enter the MTH Item number of the engine you want to check and select the manual icon to download or view it. You will need Adobe Acrobat Reader to view the manual.
PS 3.0 Enhancements ® There are 4 options for operating your MTH Proto-Sound 3.0-equipped engine; -Conventional AC -Conventional DC -DCS [MTH Digital Command System] -DCC When the locomotive is placed on the track and power is applied to the track the locomotive will detect the type of control system being used and respond accordingly.
DCS/DCC Switch Your MTH PS3.0-equipped engine has a DCS/DCC selector switch (located on the underside of the tender in steam engines). To operate the engine in DCS mode, ensure the switch is set to DCS. If you wish to run the engine in DCC mode, ensure the switch is set to DCC.
Conventional AC Operation When using conventional AC power, the engine will respond to changes in track voltage. An increase in track voltage will increase the locomotive speed and a reduction in track voltage will reduce the engine speed. A short interruption (approximately 1 to 2 seconds) in the track voltage will cause the engine to cycle in the sequence for each track voltage interruption (neutral –...
® Proto-Sound 3.0 Conventional AC Operating Instructions ® Activating Proto-Sound 3.0 Conventional AC Mode Features Throttle - To increase or decrease track voltage, and therefore train speed, turn the throttle control knob. Turning clockwise will increase voltage and speed, while turning counterclockwise will decrease voltage and speed.
Manual Volume Control To adjust the volume of all sounds made by this engine, turn the manual volume control (fig. 3) clockwise to increase the volume and counterclockwise to reduce the volume. Turning the manual volume control completely counterclockwise ® Proto-Sound 3.0 will turn of all of the engine Manual Volume...
Passenger/Freight Announcements (PFA) Your engine is equipped with a sound package of either passenger station announce- ments or freight yard sounds that you can play when you pull into a station or a yard. 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 PFA sufficient time to run through each sequence.
Tips on Using PFA •You can terminate PFA at any time by turning off power to the track for 15 seconds. •You do not have to be in Forward to use PFA. At the conclusion of the full sequence, the train will pull away from the station or yard in whatever direction you were going when you activated the feature.
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.
Reset to Factory Default To override the settings you currently have assigned to the engine and reset it to its factory defaults, while in Neutral tap the Horn button quickly once, followed by five quick taps of the Bell button, allowing approximately ½ second to lapse between each quick button press.
NOTE – If you apply more than 9.0VDC to the engine at start-up the engine will not move. This is normal. We refer to this as “Anti-Jackrabbit” and this feature prevents your model from taking off at high track voltages. Simply lower the track voltage down below 9.0VDC and then back up to get your engine moving.
Basic DCC Operation: Your MTH PS3.0-equipped engine takes full advantage of DCC's capabilities. Below are the basic commands you'll want to know to get started running quickly. Please refer to the Advanced DCC Operation section of the manual if you want to dig into the full capability of DCC.
Bell/Whistle (Horn) F1 – Bell. To activate the Bell press F1. To deactivate it, hit F1 again F2 – Whistle (Horn) To activate the Whistle/Horn, press F2. To shut it off either let off the F2 button or press and release it F4 –...
Master Volume F6 – Master Volume There are 10 volume levels. Pressing F6 twice (toggling on then off) raises the Master Volume one level. The Master Volume loops. That is, if you go past the 10th level it will loop back around to the 1st or lowest volume level. Couplers Your MTH PS3.0-equipped engine comes with remotely controlled Proto-Couplers.
Engine Sounds F25 – Engine Sounds You can turn the Engine Sounds On/Off by pressing the F25 button. Pressing it once (enabling F25) will cause the Engine Sounds to shut off. The Whistle/Horn and Bell sounds will still be active, however. To turn the engine sounds back on press the F25 button again (disable F25).

F22 – Coupler Slack When an engine hooks up and pulls a train it has to take up the coupler slack. You can play this sound by pressing F22 twice (toggling on then off). This feature works two ways – While the engine is sitting still, press F22 twice to enable it. Then, when you move the engine, it will play the Coupler Slack sound.

CV29 CV29 is the basic decoder setup CV that is used by all DCC decoder manufactures. So, if you are familiar with CV29 from other manufacturer's decoders MTH's is no different. The most important part of CV29 is the ability to switch between long and short addressing.
To change your engine's Long Address using PoM: 1. Call up the current engine's address on your DCC handheld 2. Enter Programming on the Main on your DCC handheld 3. In this step you have to tell the MTH engine that you want it to start looking at long addresses.
Page 22
unsure of the engine address you can apply the 55-55-55 reset (send a value of 55 to CV55 to engine address 55). In order for this to work correctly the engine's address must NOT be 55. The engine will need to be sitting at some address other than 55. Below is the method (55-55-55 Reset) you can employ to return an engine to its factory default short address of 3 (it will also set the engine's long address back to its default –...
MTH PS3.0 Expanded DCC Functionality Advanced DCC Operation: This section of the manual provides more in-depth detail on how to set up and configure your MTH PS3.0-equipped engine using the NMRA-standard CV's as well as the manufacturer-specific CV's. It also explains some of the other F Functions not covered in the Basic DCC Operation section.
Page 24

User-Settable F-Function List This feature allows you to take the 28 F-Functions that currently reside in each MTH Proto-Sound 3.0-equipped O-Gauge Engine and change the location of that function. For example: F4 is currently PFA and you'd like that placed down to F28 which is Feature Reset.
Page 26
The above list includes ALL F functions that an MTH PS3 engine could have. You are free to change any of the above listed items to any F function position, 1-28. For example, if you your engine came from the factory without a smoke unit but you added one at a later date you could swap out any of the F functions, 1-28, for the Smoke On/Off and the Smoke Volume.
Advanced Consisting Advanced Consisting follows the NMRA standards. Any values assigned to CV's 21-24 are ignored once the consist is removed (CV19 set to 0). Setting the MSB (Bit 7) of CV19 tells the engine that it is facing reverse in the consist Setting CV21 and CV22 determine which F Functions the consist responds to See diagram below for example Engine 3 - Rear...
Page 28
To set this consists up so that: *The Headlight is ON in the Front engine when going Forward, OFF when the consist is in Reverse *The Reverse light and headlight is OFF in the Rear engine when the consist is going Forward, headlight is ON, reverse light is OFF when the consist is in Reverse The Middle engine has no lights in either direction Perform the following:...
Page 29
11. Call up the consist address (address 4 in this example) 12. Press the F0 button to ensure the FL is toggled on. Most systems have a light bulb icon to indicate whether F0 is active or not. Ensure that it is ON NOTE –...
NOTE - CV21 is ONLY used when you have some value other than 0 written to CV19. If CV19 = 0 then the values of CV21, CV22, CV23, and CV24 are not used 1. Call up your Middle engine (address 2 in the example) 2.
Page 31
So, in the above example you simply add up the values in the “Decimal Value” row – 128+64+0+16+8 +0+0+1 = 217. You would write 217 to the CV you were altering. The above applies to any CV. Also, if you have a CV that already has a value assigned that you do not want to alter but need to make additions to it, for example CV29, you would simply add the additional bits you enabled to the existing value to obtain the new CV value.
Maintenance Lubricating and Greasing Instructions The engine should be well oiled and greased in order to run properly. Regularly lubricate all axles and pickup rollers to prevent squeaking. DO NOT DO NOT Use light household oil, such as that found in M.T.H.'s maintenance OVER OIL OVER OIL kit.
