How to fit SFX Sound into N Gauge guide

Many modellers like the extra realism which sound can bring to a layout but until now it has been an expensive and complicated feature to add & usually requiring DCC, extra wiring and quite a lot of space. SFX needs none of this and works in ANY train! Priced at £45

How does it work? 

At the heart of each SFX is a microchip containing the real recorded train sounds and a small motion sensor which detects what the train is doing and replays the most appropriate sounds through its tiny loudspeaker. The motion sensor also turns on and off power so that there is no need for any switch and battery life is preserved.
