You can hear that when a short circuit occurs, but you also hear it from several locos with a sound module. With my locos, this sound is at a very low level and I don't think I need unpowered tracks to park those locos. Hard to tell from the distance if your loco just has the normal buzzing sound at a low level or if there is a problem with a higher noise level.

If you use a new control unit, not the 6021, but the newer Märklin CS or ESU 50210, and newer protocols such as DCC and RailCom enabled, especially the latter will probably be the cause of the "buzzing" sound.
