Digital model railway control systems
open-in-new
<p>Digital model railway control systems are an alternative to control a layout and simplify the wiring and add more flexibility in operations. A number of control systems are available to operate locomotives on <a href="/facts/Model_railway/Dvd8BwBg">model railways</a>. Analog systems where the speed and the direction of a train is controlled by adjusting the voltage on the track are still popular while they have recently given way to control systems based on computer technology. </p>
