So, I just ordered a 1K ohm logarithmic taper potentiometer (variable resistor) that I plan to wire into the speaker circuit on mine. I'm planning to have the adjustment shaft end accessible from underneath, just flush with the bottom of the frame so you don't see it.
By limiting the output current from the audio amplifier, it may sound better. It will definitely be quieter and I will finally be able to adjust the volume and hopefully enjoy the locomotive's "operational" sounds.

I'd change that to something lower in value, a 1K is going to pretty much kill the sound. Consider a 200 ohm pot max for the task.
