Good to hear no issues with the latest f/w on the 4400's, I had heard they did firmware mods, but not the specific version, and could not confirm they were in the LS Tsunamis...

Since you are consisting, and as I remember mostly flat, that all makes a "low risk" situation for overload. Too bad that NCE would not allow the mod any more.

I actually have a diagram somewhere of the mod...

Was out of pocket all yesterday at a conference (10 gigabyte symmetrical fiber to the home), so missed post #31, thanks!

Funny, after years of undergauge and under spec back to back, now they are over 1.575!

Sorry to ask for one more thing, but the thickness of the base of the flange is of interest since the back to back is so wide. Hard to measure, because you don't want the fillet, so the base thickness of the flange near the tread, but not on the fillet if that makes sense.

How they run will be interesting...

Stay warm, Greg

Hey Greg can you take a pic or make a drawing of what exactly you want me to measure, not following you sry.

Well crap New TSU-4400 board came today and it's no good 鈽.

First I thought it was the Dash-9 as none of the J2 functions or sound worked. Then I disconnected the board and wired it up to the UP FA I just did and no sound or j2 functions still, a real bummer.

As to the wheels used on the Bachmann Dash-9 (should be same for SD45, E8/9, GP40), I wonder if the plating quality is better than the original Aristo wheels (important for track power users).
The stainless steel wheels with reduced flange depth I had made for me by Datum Precision (hopefully with same as Aristo axle taper of 8 degrees.) may fit a bit wider back to back if Bachmann has their wheels pretty much to spec. of 1.575 inch, close to Ron's measurement of 40.21mm (1.583 inch).

The plating of the GP40 wheel on the right in below picture is bad.

Just a quick note

Bobs back to back measurements of 40.21mm are correct to the Standards which is between 39.64mm and 40.38mm. I am a little unsure that Bobs measurements for the Check Guage have the Calipers in the proper place on both wheels but the check guage appears to be within range as well.

I hope you get a working decoder soon. Since your QSI decoder does not support the extra functions you can wire the Dash-9 "-" connection to the desired functions on Dash-9's main board. This will allow the switches to work as you desire using your existing QSI board.

Yes, appear to meet standard, but that is the reason I asked about flange thickness...

Again, if you read my posts Stan, you would know that the QSI board in question has no extra lighting functions, again you seem to have mixed up the QSI Quantum Revolution with the QSI Titan.

Well got it all apart here are some pics.

The fuel tank weight plates weigh about 1lb 12.8oz, and new weights about 5lbs (2 lead, 1 new type Aristo)

Be careful separating the shell and cab from frame. The cab is very tight fit it's best if you use a very thin flat blade screw driver and slowly pry it up from frame a little bit at a time switching from side to side as you go, the long rectangular tool box on right side just aft of the cab does not come off with body and cab, mine had a little glue attaching it to the body so if felt as it was attached to body shell. If you take body shell off separately from cab you risk breaking the tiny safety lights that are part of the cab but wires attach to body half.

Here are some pics of main frame, close ups of the PCB boards, and new speaker.

Average running light on level track?
on a grade?
full stall?
full slip?

All different numbers, but your motor blocks should draw an amp or less each running on rollers. The whole loco running on rails should be under 2 amps running light.

Why do you ask?

Mostly level biggest grade is about 1.5%, and yes to all of the above.

Just curious how much power it draws.

Does anyone know what the current draw is for the Dash-9?
Taken from John Welther's review in GR magazine:
I was impressed by how the model ran straight out of the box. The more I ran it, the better it performed. At the time I tested it for amp and voltage draw, it had about 20 hours of run time on it. At that time the model registered just a whisker under 3 volts starting power. At 3.5 volts and 2.25 amps the model ran without stall or hesitation at about 1.5 scale miles an hour. Maximum speed was near 20 volts with 3.25 amps. This worked out to be roughly 60 scale miles an hour. Drawbar pull at full load was 86 ounces, or about 70 average freight cars.

Is that the blunami board ?
It doesn't come with any board, just a speaker that plugs into main PCB board and supposedly works with the PNP socket, don't know for sure yet because the TSU-4400 board I wired up was bad, it didn't work with the qsi one I tried in the pnp had to plug speaker directly into qsi.

I have a replacement coming on Monday so will find out then, using the adapter board.

Unfortunately there are no new or in production boards available (Zimo and Phoenix boards are na with no expected availability dates) for the PNP socket.

Well I got the new Soundtraxx TSU-4400 installed using the PNP adapter board and am happy to report All the individual lights and smoke unit are now controllable using the function keys on the handheld without any additional wiring.

Once the board manufacturers start making new PnP boards for this engine a truly fully controllable DCC installation will only take a few minutes. Bachmann has done an amazing job with this engine, can't wait for the new GP40s and E-8s.

Here's a quick video of the results,
