Trainorama GM Class DCC Sound Installation

with Lighting Modifications

This GM Class page will be updated soon to include all the new changes and remastered sound for this installation

The Trainorama GM includes an 8 Pin socket for easily fitting a DCC decoder plus a 4 pin sound ready speaker socket with two 8 ohm speakers making it a simple solution for sound.

In this installation we have chosen the ESU Loksound Range of 8 Pin decoders, such as the Loksound Select (Sound), LokSound V4.0 (Sound) or LokPilot V4.0 (No Sound)


Replacing the rear light with an LED and providing on/off control rather than directional using AUX 2.Separating the front markers and number boards from the headlight and operating them on AUX 1.For better quality sound using the factory installed speakers we need to install speaker sound enclosures to eliminate the sound waves produced from the back of the speaker, mixing with the sound waves produced from the front of the speaker. Avoiding this will produce sound that has less volume, lower bass and will sound “tinny”. The sound difference is remarkable.We have tweaked the motor control to provide super smooth slow speeds at steps 1-10 of 128 which is perfect for those wanting the locomotive to move off slowly and build up speed like the prototype.
