Has anybody converted or used a dcc train on a dc layout. Can the dcc stuff be taken out. This may be to early to ask this question as I have just bought 4-4-0 JUPITER on e-bay without knowing the answer to that question! I know dcc can be run on dc track but will not act right without doing something. Does anybody know an answer for me.
I'm not sorry to buy without knowing the answer I wanted the train anyway.
THANKS AL

If the DCC locomotive comes with a jumper to plug into the DCC header when the DCC decoder is removed, then yes, it should be able to be operated on a DC system.

I have never bought a DCC equipped locomotive that included this jumper. I have purchased DCC-Ready locomotives that have included it.

Some, most, all of the newer (?) DCC decoders have a DC mode. If there is sound you'll get it making sound at various voltages. Aspects of that can be set with say jmri, including turning the sound off (probably). Since you have it already why don't you just stick it on the track and apply voltage and see if it moves or does something. My experience is limited here to some recent stuff. But the settings include how much voltage is needed to get it going.

That's a good point. Look for the jumper ... If it has one you can do that. Although the dual mode DCC/DC is nice it kinda presumes you are DCC going to odd DC only layout .. I think at least. This to me is where an external way to adjust sound level that doesn't involve removing the shell and ripping the speaker out. Would be nice ...

I am by no means a expert on this one!!
I however do know I have 2 Bachmann 2-8-4 berks with DCC onboard. They can run on a DCC track/ layout. Ready to run out of the package! That’s what I was told.
I also know my layout is not DCC!! lol
I run them all the time on it. No problem with them. Of course I don’t know about the DCC aspect of them yet. Maybe I did mess up the decoders
I just know they work good on my layout.

I don't have this train yet just bought it on e-bay 2 hrs ago used with 30 day return. I think the train will have dcc but don't really know. I have dc and want to stay with dc so will wait until I get it then see what can be done.
If I have to remove dcc from it will check that out. IRON man that is what I was hoping.
THANKS AL

Hopefully it works out for you!!
I know I was happy when mine just went right on the track & took off!

Yes newer decoders will operate on DC only, I just don't know how to tell if it "dual mode" or not. Putting it on a DC track and trying it won't harm it. It will work or it won't. If its used then its possible that its also been set to not work on DC. In that case you will need to find some one to change the decoder setting.

As the others have said, a DCC loco of recent manufacture is almost certain to work on a DC layout. You're just missing out on the much finer control over the motor, lights, and sound that DCC provides.

Hopefully, that Jupiter is one of the new ones made for the 150th anniversary of the Golden Spike ceremony last year, and not something that has been in someone's basement for a decade.

From day one, DCC modules have been required to pass the DC signal to the motor, like it was not there. If your using a DC signal with no PMW, all is good and the engine runs like it is on DC. If your DC power supply produces a PMW, which most do at settings below 9 volts, then the module thinks it is a DCC signal with erratic results. Some more recent modules have additional electronics in the circuit to help with this. Even then it will be dependent on your DC power supply.
Good luck with your new model.

Modern decoders can be rendered unresponsive to DC power to the rails simply by configuring CV29 to a value of 38. If you don't wish to have it ever respond to DC power, say if it gets to the rails by mistake, you change CV29 to another value, 34 if the decoder has a 'long/extended' address, and I forget what the other value is for a short address. Google 'CV29 cal..." and you'll instantly get several offerings of calculators with the tables showing what else will change in CV29 if you programme it with a range of possible values. Run down the table, find the best fit, and then go and programme yours accordingly. You can do this in Ops Mode/Programming on the Main.
