    1100s. Just to add some interest for railfans, these were numbered 1430-1444. At the time of writing, many GMD-1 locomotives are still in service today and there is talk of a further rebuild program.
  • Page 5: Break-In

    We suggest that, after reading this manual, you put your GMD-1 on a test loop and just let it run in each direction for an hour or two. Fast and slow.
  • Page 6: Ditch Lights

    DITCH LIGHTS The neatest innovation on our rebuilt GMD-1 model is the ditch lights. We’re very happy with the way the ditch lights turned out and we hope you will be too. It is extremely dif- ficult to make deck-mounted, tall-stalk ditch lights that actually work.

    REMOVING THE SHELL If you need to open up your GMD-1 (to install a crew, install a decoder, etc.) it is actually quite easy to do. Just be sure to remember these important points: •...

    This is available for download on the GMD-1 page in the Support section of our web site. You will need an ESU LokProgram- mer to write the function mapping to the 54615 decoder. If you don’t have a LokPro- grammer, you can adjust CVs in the usual way.

    GMD-1, for good or for ill. As always, we’ll try to help you fix your GMD-1 if one of these doo-dads scrambles your locomotive’s circuitry, but we can’t guarantee we’ll be able to.

    “clearing slot #36.” A basic summary of how to do this can be found on the GMD-1 page in the Support section of our web site. More detailed information can be found on the Digitrax web site.

    F8 is pressed so it will keep idling along. However, if someone else selects your locomotive’s number and F8 isn’t pressed on his or her controller, the GMD-1 will promptly shut down. He or she will need to press F8 again.

    We chose a nice one. F2 Horn Since our first GMD-1 release we have improved the horn file to make it easier to do a short “toot” without having a long tail off. To get a short “toot” just tap F2 or your “HORN”...
  • Page 13 F20 and F21 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...

    Make sure you turn off F20 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 ac- cumulated saliva.

    0-128 FACTORY RESET On your GMD-1, you perform a factory reset by entering a value of “8” into CV 8. Note that this will cause all of your new volume and motor settings to be lost, so you will need to reprogram any settings that you want to keep.

    This is available on the GMD-1 page in the Support section of our web site. LIMITED LIFETIME WARRANTY We will do our best to solve any problems or issues that you may have with your GMD-1 locomotive. If your locomotive has any defects that originate from the factory, we will repair your locomotive using new components or replace it outright should a repair not be possible.

    Of course, damage caused by running your GMD-1 at full speed around a 15”-radius curve along the edge of your layout, modifying your GMD-1 to work off diesel fuel, not modifying your GMD-1 to work off diesel fuel but still filling it with diesel fuel, strapping your GMD-1 to a rocket for an entertaining YouTube video, or any other damage caused by you that we haven’t been able to cover here is not covered by the warranty.
