Whilst the RailKing HO gauge locomotives can operate with a traditional 12 to 24 volt dc transformer/controller with "automatic" smoke and sound effects the use of a modern sound compatible controller will allow the benefit of the Protosound-3 units that are built into these models. If all the track-powered locomotives are under digital command control then the transformer need only provide a fixed output. Using MTH controllers there are basically two options; firstly there is the DCS Commander (which if used with the MTH 110 volt transformer will need a step-down transformer, or you can power it your own ac or dc 18 volt supply). Secondly the DCS handset in combination with a TIU can be used to control multiple locomotives (and also trackside accessories via the AIU). The TIU can be fed with 18 to 22 volts dc from a plain transformer-rectifier or sets of batteries. We have heard of people using NiCd, NiMH and traditional lead-acid cells as power sources and of course the handset gives control of all four outputs of the TIU without being fixed near a control panel or dragging a cable around. The DCS Commander on the other hand is a lot more compact, it has the facility to "pass through" DCC command signals if you already use a DCC controller whilst also having the facility to act as a variable voltage controller for traditional non-digital locomotives. The protosound 3 locomotive decoder will also decode DCC commands if your track is already fitted with that system. Around two dozen effects can be controlled using DCC (assuming your DCC controller will output the "higher number" commands) but if you want the full true range of Protosound 3 then you should consider DCS. The locomotives will run when powered by a 12 volt controller but for maximum speed and power require 16 volts. The Protosound 3 locomotive decoders are capable of taking a maximum of 24 volts. Please note that if you are running DCC locomotives then you cannot use DCS on the same track at the same time. You can use a DCC controller with the DCS Commander in "pass through" mode or you can activate the DCS Commander which will then block DCC control signals. Please also note that, unlike the Protosound 2 controllers used in gauges 1 and O, the Ho locomotives should not be fed directly with an ac supply, to be specific the DCS commander will provide a rectified supply if fed from an ac transformer but, for MTH Ho models, a TIU must be fed from a dc supply.
