I have apartment Norfolk Southern SD40 soon as I program my address into it and like to test it out soon as I went to speed step on it was like on speed step 20 what went wrong and how do I fix

I prefer the Kadie knuckle style couplers they're pretty reliable and as long as you have them lined up they act pretty good and they resemble the real thing and Kadie makes couplers that works off DCC now where you can uncouple

I also have a Athearn Union Pacific SD 50 its DCC ready with the DCC adapter board in it thinking about going with the soundtraxx econami decoder,, I just bought a Bachmann Norfolk Southern SD40 - 2  with decoder and sound ready to go,, I also have an Athearn Union Pacific SD40 T - 2  I need to get a decoder for it,, and I have a much older 1984 Bachmann DD40AX Union Pacific that I want to put a decoder in,,,any suggestions?

Yeah i was watching some youtube videos on digitrax the zepher express looks like the way to go,,it has the loconet jacks to plug in the lnwi,,,and i can probably get all that for around two bills at which i was looking to spend,,,thanks bapguy and jward!!!

 I'm looking to control things with my tablet do I need some kind of Command Center or handheld throttle to go along with that lnwi

I'm new to this DCC thing I'm looking at the digitrax system from what I understand all I need is a db210 booster with auto reverse and the new lnwi for Android and I'm good to go if I need any more let me know please

 does anyone know the formula for pulling power for HO scale locomotives?

Thank you Terry,,,cant wait to slap a decoder inside of her,,and bring her to the new millenium!! I bet she's a workhorse!!

I read up on it and they say they got speakers that you could strategically hide in your layout and the speakers actually follow the locomotive with the sound so actually makes it sound like it's coming from the locomotive which I think is pretty cool I like that concept

Did'nt i say somethings gotta work,,,just finished installing the 2nd pancake motor in the DD40AX and cher she is pulling now and i also have a spare pancake motor!!
"SUCCESS"       

Well Terry looks like they ain't left nothing out LOL. I was reading up on the digitrax system does it require a full internet connection or does it work off of Wi-Fi Direct,, and if it does need a full internet connection will a hot spot suffice?

Yeah you say the sound wouldn't it be awesome to incorporate some kind of surround sound into your layout with like Dolby 7.1 surround and an awesome sub box the sound would be phenomenal then!!

The faulty one may have fried the other one that you been having, that's most likely the issue but you know most companies since it was pre-existing they are not going to replace it but it's cool that they're replacing the faulty one,, I posted a question in my topic "decoders" I'm looking at using my Android tablet as a controller how do I go about doing that?

Do you have the polarity right?
