Overview RailBoss 4 Basic is an electronic speed control designed specifically for controlling large scale trains using a small hand- held 2.4GHZ transmitter. It provides all of the basic speed control and sound functions you would expect. Precise speed control with selectable rates for •...
Locomotive Hardware consists of a RailBoss 4 Rx (combined control board and receiver, 3.2” X 2.0” ), and an optional reed switch for automated station stops (the Bell reed from your sound system can be used for both station stops and the bell). The Handheld Transmitter can be used to control your entire fleet of locos, any one at a time.
built into the RailBoss 4. The front and rear lights follow the direction of the locomotive. The front light is also used as feedback to the operator during programming procedures and low battery warning. Four user defined outputs controlled from the transmitter can be used for sound triggers, phoenix un-couplers, or smoke units.
For smaller locos you may need to install some of all of the system in a trailing car. The G-Scale Graphics “Battery Power Conversion Module” makes installation easier in many cases by putting the on/off switch, fuse, and charging jack all one small circuit board with screw terminals to eliminate soldering.

Note: A G-Scale Graphics “Battery Conversion module” will greatly simplify the power input wiring and provide screw terminals for connections. A 5-amp fuse in-line with the battery input is recommended. This is also included in the G-Scale Graphics “Battery Conversion module”. (10 amp models should use a 10-amp fuse).
Sound Triggers Outputs are provided for up to four sound triggers to a sound board. These are open collector outputs that pull the sound board input low to common (ground) to trigger the sound. The battery common (-), connected to both the RailBoss and the sound board is the return path.
Reed Switches Closing the reed switch with a magnet, or by moving the loco over a track magnet, will cause the LED to turn off while the contacts are closed. If not, check the wiring. Manual Operation Power-Up At power-up, the locomotive will be stopped, ready to proceed forward. Momentum is off (fast rate), station stops are disabled and auto track whistle is enabled.
To set min speed, use the Faster button to just barely get the loco moving. Then use the Slower button to just Stop it. Press Bell to save the min speed (Speed must be less than 50% battery voltage). To set max speed, use the Faster and Slower buttons to run the loco at the desired speed. Press Whistle to save the max speed setting (Speed must be greater than 50% battery voltage).
RailBoss 4 Transmitter Commands Single Key Function Key function Examples: Press “Bell” key once to sound the bell. Press the “2 Key”, followed by the “Bell” key to Toggle Station Stops. Whistle - Press momentarily to sound the Whistle/Horn (Sound trigger 1) or hold for sound systems with “playable”...

Automated Operation An automated station stop slows down the train, waits at the station for a predetermined time, then accelerates back to its original running speed. Station stops add interest to your open house or public displays. Automated operation is easily achieved with the RailBoss R/C Control. You just need to add a reed switch to your locomotive and place some track magnets on your layout.
board. The whistle reed switch can remain connected to your sound board, in parallel with the RailBoss sound trigger, and it will operate as normal. The whistle reed switch at terminals 11,13 triggers the sound board via the whistle sound trigger. The advantage here is, the RailBoss has some optional randomization functions, which will only sound the whistle a certain per- centage of the time the reed switch passes over the track magnet.
Multi-Train (Automatic Train Separation) Run two or more trains on the same loop, making random station stops, unattended. Each train will make station stops as programmed in User Parameter 3. When a train stops at the station, it will remain there until another train releases it by passing over a whistle magnet.
A single train running in Multi-Train mode will make timed stations stops until a second Multi-Train loco is powered up. Then the train will wait at the station for a release command at the whistle magnet by the second train. Once properly setup, you can enjoy running multiple trains for hours with no intervention.
User Programming via the DIP Switch & Push Button Some of the operating parameters of the RailBoss Plus can be modified to meet your individual needs. No pro- gramming is necessary to get your system up and running, only to modify it, if so desired. User configurable parameters can be programmed using the 4-position DIP switch, the on-board push-button next to the DIP switch, and on-board LED.

Note 1) The radio systems used in each of our RailBoss R/C systems operate at 2.4GHZ. However, they are NOT compatible with each other. The RailBoss 4 control board may only be used with a G-Scale Graphics RailBoss 4 Transmitter, and the Hobby RailBoss boards may only be used with 3rd party hobby transmitters and receivers.
