Sound & Lighting sets for new S Stock models!

In partnership with London Transport Museum we are proud to launch lighting and sound sets specially designed for the Museum’s brand new S Stock Motorised model tube train.

These special sets have been developed by Train-Tech to bring extra realism to these stunning new models by allowing modellers and collectors to add full interior lighting, under-train spark-arcing effects and authentic door open and closing sounds.

Each light and sound strip is powered from a small readily available coin cell battery and uses Train-Tech’s unique motion sensing technology to automatically switch on and off lighting, spark effects and door tones. As soon as the train starts moving the lighting comes on and as it moves along the track it realistically flashes the spark LEDs underneath the driving cars. Once the train comes to a halt the spark effects cease but the interior lighting remains on and after a few seconds the distinctive door opening and closing tones sound. If the train is stationary for more than four minutes all the lighting and effects shutdown to automatically preserve battery power.

The strips are easily retrofitted into the roof of any of the new S Stock sets with no soldering, wires or special tools required and full instructions are supplied. And because each strip is independently powered on its own battery they work equally well on both regular DC and Digital DCC layouts with no flicker, pick-ups or switches required - all are wire-free and completely automatic. As the lighting and sound effects all work without needing any power to the track they are also likely to be popular with collectors who just intend to display rather than run their models.

Like all Train-Tech products these sets are both designed and manufactured in the UK.
