DCC power usage

I made this video to show how much power a DCC locomotive actually uses. Newbies to DCC are sometimes scared off by false information about power usage. There are 4 N Scale locomotives with sound enabled and it draws about 0.5A. In this case the booster is supplied with an 8A power supply that also provides power to several Digitrax components (UR93, DCS52 in thgrottle mode, DT602D).
