FUNCTIONS: MORE INFORMaTION

F3 “Straight to 8”

This unique feature simulates the prototypical operation of the GMD-1 locomotive. If you 

are switching out an industry and you are having trouble pulling those heavy grain cars 

out of the siding, you will want to put the GMD-1 consist straight into 8. That means you 

move right into notch 8 (rather than going through the notches slowly) and gun it - wheel 

slip and all (and there is a LOT of wheel slip).

Obviously, this sounds very different from a typical freight engine slowly notching up to 

8 and back down again. When F3 is selected, applying any throttle to the locomotive 

will cause the locomotive sound to ramp up quickly to “Run 8” (full power). If you decel-

erate, it will go right back down to idle. If you push F3 when the locomotive is at notch 

8 and then you decelerate, it will notch down normally. Note that this function controls 

the sound only and not the motor speed. Motor speed is still controlled using the throttle 

settings as normal.

If you want your consisted engines to respond to F3 when you press it, refer to your DCC 

system to check how consisted engines respond to functions. You may need to change 

some CV settings in your consisted engines following the detailed instructions in sec-

tion 5.2.3 of the ESU Loksound Select decoder manual, available for download on the  

GMD-1 page in the Support section of our web site.

F4 and F6 Sarco Valve (Spitter)

These functions turn on or off the Sarco Valve. On the real GMD-1, it’s always going. But 

you often can’t hear it from a distance. In contrast, if you are close to the engine you can 

hear the Sarco valve pretty prominently. We feel that on many sound-equipped engines, 

the Sarco Valve is way too loud. So we’ve included two versions of it, controlled by 

functions. You can choose whether or not you hear the Sarco Valve, and you can choose 

how fast you want it to spit.

If you press F4, the Sarco Valve will be heard intermittently. If you press F6, it will be 

heard less intermittently. Make sure you turn off F4 first. 

If you have a silent GMD-1 and you want to recreate the Sarco Valve effect, please aim 

away from the models. Your GMD-1 warranty does not include malfunction due to spit.

F5 Doppler Horn

Play this when approaching level crossings. We planned to include our Doppler horn 

as used on the FP9A, but as that train was doing about 80MPH when the horn was 

recorded we didn’t think it appropriate to use that recording for the GMD-1. The train in 

this recording is going a wee bit slower.
