Self contained capsule, built in speaker and battery
Tiny, smaller than a 50p piece at just 25 x 20 x 12mm
Can be fitted into a locomotive, tender, wagon or coach
Real recorded sounds
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 the tiny loudspeaker. The motion sensor also turns the power on and off so there is no need for a switch and ensures that battery life is preserved.
