GMD-1 LOCOMOTIVE PRODUCT GUIDELINES Thank you for purchasing this model of Canada’s most unique locomotive, the GMD-1. This is the first freight locomotive produced by Rapido and the first locomotive produced by the MLW factory. (Funny that MLW’s first model is a GMDD prototype..don’t tell...

30 seconds. That is not enough time to get the gears to mesh nicely or to even out any jerky operation in a new motor. 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.
EXTRa STUFF IN THE BOX You can run your GMD-1 right out of the box. You don’t need to add anything to it as all of the basic grab irons and other details are installed. (The exception is the area on the long hood above the radiator for CN 1954 1000-series models.
CN removed them over time, first cutting them down to four and then to none. In our opinion, reliable operation is more important than installing a detail that might cause you a big headache. If you plan to actually run your GMD-1, just leave them off. CHECKING aND aDJUSTING YOUR LOCOMOTIVE...
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: • We have a transporter lock on the molecular pattern of your locomotive. If some- thing pops off while you are removing the shell, our starship’s transporters will...
• No, really. OPERaTION – DC (SILENT) If your GMD-1 locomotive is not equipped with a sound decoder, it should function like most other HO scale locomotives. The gear ratio is 14:1 so there is a good chance that it will MU (multiple unit) with your existing fleet. Put it on the track. Give it some juice.
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.
Press F8 again to turn the sound off. Note that if you are listening to your GMD-1 idling nicely and then you select another engine, your GMD-1 still thinks F8 is pressed so it will keep idling along. However, if someone else selects your GMD-1’s number and F8 isn’t pressed on his or her controller,...
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).
Green class lights mean a second section is following. Red class lights mean the engine is pushing a passenger train. While we would love to see the GMD-1 hauling the Super Continental during the Expo 67 rush or pushing GO trains in com- muter service, these events are not entirely likely.

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.
