Thank you. I don't visibly see a bachmann decoder. It just looks like a whole circuit board. It has a 21-pin connection, but I'm getting the impression I can't just attach a decoder to that 21 pin connector (is that for a proprietary sound board?). Is that true?

Also, these 2 speakers that came in the loco won't work with Blunami? I can swap them out if necessary - just want to confirm.

I was hoping I could just pop a decoder on the 21-pin connector, but it sounds like I need to remove all electronics from this train in order to use a Blunami. Is that true?

I purchased an On30 Whitcomb 50-ton center cab diesel.  It says "Sound Ready - DCC equipped". My definite intent is to put a specific DCC decoder in it (Blunai). I thought it came with a standard 21-pin decoder connector - and that I could just plug into that.  As I'm looking through it with the shell open, it mentions a "Whitcomb sound module" and I'm starting to question if I can just plug in a decoder so easily.

What is the process for me putting my own decoder (Blunami) inside this loco?

As far as I can tell 2 of the most popular products out there are the Blunami and the Dash9. I wish the Dash9 was available with a Blunami decoder pre-installed.

I have SoundTraxx Blunami boards. Now my kids want Blunami Thomas. We need Blunami Thomas.

No, but you can see a photo of them here:  https://estore.bachmanntrains.com/index.php?main_page=index&cPath=722

No. EZ App isn't intended for this. EZ App trains can be put in DC mode by toggling the direction button back and forth on a standard transformer. Once in DC mode, the circuit board falls asleep if you bring the throttle to "0", so you never bring the throttle all the way down. The loco stops at about 15% power.

I was at Amherst and saw the SoundTraxx Blunami boards. Any chance we'll aver have any of that in Bachmann? I am mostly into Large Scale and Thomas.

EZ App Android has been updated to function on the latest version of Android.

The latest version is 1.2.134 released on June 11, 2021.

You do NOT need a phone plan on any device to run trains.  A good device for running EZ App is an iPhone 6s plus 16 GB which you can buy on eBay in the $50 range. No plan required. You will need an email address to create a free AppleID which will be needed to download the free app.

Does anyone know the amperage draw on a Williams GP9?

Do EZ App boards have an LED on the board that lights up when the board is receiving power?

I'm not talking about the headlight LED - I mean a small indicator on the board to let you see when it is receiving power.

You do NOT need a phone service to run these trains. You can purchase an iPhone6s plus 16 GB for ~ $50 on eBay, download the free Bachmann EZ app and run the trains.

You do NOT need a phone service or any type of account associated with the phone. You can also use a tablet (like an iPad or an Android tablet).

It is a very affordable controller for a train, and works with bluetooth (which is built into the phone/tablet).

You will need to have an email address to get onto the Appstore or the GooglePlay store to download the free control app.

Will Williams locos operate on DC power? Or does the track have to have AC?

Always available in the Bachmann EZ App. 3 free songs come with the app. You have the option to buy 6 more in iOS. The trains move in sync to the Christmas music.

The EZ App is designed to control Bachmann EZ App locos.  You use an Android or iPhone as your remote using the free app.
