SFX70+ Goods Shunting Sounds Capsule

This sound capsule adds real sound to your layout - self contained and easy to fit with no wires, switch or pickups.

SFX is a self contained sound capsule for model trains and requires no connections because it is battery powered and uses a motion sensor to detect whether it is stationary or moving and a microprocessor to play appropriate real train sounds! No on-off switch is required because it turns itself on automatically as soon as it moves, then switches off after it has been still for a while to save battery.

Easy to fit in seconds - no wiring or switches!

• No pickups or wires - works on regular DC & DCC

• Self contained capsule - built-in speaker & battery (Supplied)

Tiny - smaller than a 50p: 25mm x 20mm x 12mm

• Fit capsule into a loco, tender, wagon, coach....

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 the 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.

SFX70 Goods shunting Sounds

These are the sounds you can expect to hear from your SFX70. They are not simulated effects but real sounds recorded by us from loose coupled stock on the North Norfolk Railway ( plus a few wheel squeals from the Mid Norfolk Railway (

• Stationary - nothing at all! The capsule knows nothing is moving and so remains completely silent waiting for motion.

• As soon as the capsule detects motion it starts playing the sounds of wheels slowly squealing to life...

• Then the clanks, bangs and creaks of loose coupled stock being shunted around...

• The more jolts the motion sensor detects, the more often sounds are played...

• After motion completely stops the sound capsule returns to silence and waits for the next movement.

• If there is no motion for over a minute the SFX automatically goes to sleep and waits for some movement to wake it up.
