Train-Tech SFX21 Diesel Sound Capsule

This video is a demonstration of the Train Tech SFX21 Diesel Locomotive module showing how easy it is to fit and what it sounds like. The SFX Sound capsules are a series of easy to use completely self contained sound capsules which are powered by a small CR2032 coin cell battery and activated by motion so that NO wires or switches are required and they work on DC or DCC because no connections to the rails are needed.

SFX sound capsules can be fitted inside a loco, wagon or coach to bring easy to fit low cost real railway sounds to almost any layout.
All sounds are real sounds from real trains recorded by Train Tech and the video is 'as live' with no sound enhancements or other tricks - what you see is what you will get.

SFX21 sounds...
These are the sounds you can expect to hear from your SFX21. They are not simulated effects but real sounds recorded by us from Class 31 locomotives No D5631 (31207) on the North Norfolk Railway (www.nnr.co.uk) and No 31235 on the Mid Norfolk Railway (www.mnr.org.uk)

Stationary - Engine Tickover sound and the occasional compressor noise cutting in and out
Any movement triggers the sound of air release and if motion continues a single horn sounds followed by gradual speed up of the engine
After speed up engine power is maintained
The two tone horn sounds after the loco travels continuously for a while
When motion stops it returns to stationary sounds
If there is no motion for over a minute the SFX automatically goes to sleep and waits for slight movement to wake it up.
