Member video: Demonstration of Keep-Alive Digital Command Controler decoder in an HO scale short wheel base locomotive

Here’s a short demonstration showing how a DCC decoder with a Keep-Alive capacitor can help short wheel base locomotives get through complicated track work that they sometimes stall on. In this example, a TCS KAM4 decoder is installed in a Athearn SW1000 switcher. Operation of the switcher before and after installation is shown for comparison.
