MTH 2rail DCC?

[Marmight]

Can anyone please tell me if a MTH 2 rail engine with protosound 3 can be operated on DCC? The engine has ‘scale’ wheels and looks to be a factory conversion, but the info on the box doesn’t mention DCC, only DCS P3.

 

Cheers

My understanding is that the DCS system migrated to understanding DCC commands so that it can be run on a DCC system, but you can only program the the decoder with a DCS system.

Hi Tony,

 

I’ve done a bit of digging and found that later MTH locos with Protosound 3 and DCS have a DCC Decoder installed and available via a small switch under the front trucks. They’re programmable using DCC CV values and will accept short or long addresses with a bit of adjustment. All the DCS  functions appear to work from most DCC controllers. The DCC command list is a bit different from a lot of others and uses F3 for the prime mover start up procedure. F1 is still the bell and F2 the horn.

Engine with Protosound 2 are NOT DCC compatible and will require a complete rewrite and installation of a suitable decoder.

 

Cheers

I have a number of MTH Protosound 3 locomotives (which all can be controlled with a DCC system) but have not seen any small switch under the front trucks.

 

On the MTH website all instruction booklets for all locomotives can be downloaded; maybe that will help?

I have downloaded the instruction manual for the particular model, and there is a small switch under the front trucks marked dcs/DCC.

if the truck is turned to the right, just under the now exposed moulding there is the slider switch.

Oops, I now realised that you might be talking about a diesel engine; I only have steam engines where switches are located in the tender.

Sorry Fred, I should have said…
