Good Evening Group.
I would like to install a Loksound Select L decoder into a dummy locomotive to control sound and light functions of the dummy unit. The dummy unit would have its own speaker. Is this possible? Can it be done with the motor removed?
Thanks,
Stephen

Sure. There maybe a need to put a load on the decoder to kick in back EMF for motor sounds.
I presume the dummy unit is a diesel. Yes, a Loksound Select decoder will work. Since there is no motor to power, you can use one of the less-expensive HO decoders. There is no need to put a resistor across the motor leads. Loksound decoders don't use back-EMF to control sound. Also, a resistor doesn't produce back-EMF.
I would recommend pairing the decoder with a 4 ohm audiophile Tang Band 1925S speaker module, which has its own sealed enclosure and a passive subwoofer. It should fit in most diesels. In a "covered wagon" such as an F-unit, it may be possible to fit the larger T1-2025SC or even a T1-1942SB. Either of these may require removing some material inside the unit.
Here are a few links to recordings of Loksound decoders driving Tang-Band speakers. The 2008 is the smallest module they currently produce and is thin enough to fit in an older Atlas SW9, firing up through the radiator grill.
