Wisdom tells me to leave the installation to a professional. I'm at that point in life I have difficulty getting my socks on the right feet.... 
 
  Seriously, I have found from experience the first attempt at something difficult and complicated is usually not fun.

   On my Consolidation I replaced the cabbage head stack with the tapered stack. After some kind help from this site I was able to get the stack light and cable in place. But there was no hole in the stack for the fitting and without some coaching I doubt I would have found the hole in the cab front for the electric cable. Took me about three tries, after I had drilled the hole in the stock stack for the fitting, to work the electric line around the handrail and sand lines etc.

  If I had someone to be on hand to tutor me that would be another matter.

  Thanks  Jon

Thanks, Rich. Yes, I am relatively new to DCC, but amazed at it's convenience, flexibility and the quality of the sound produced. I now have several Bachmann On30 steam locos with sound just to play with as my current circumstances don't permit me the time to work on a layout.
  I guess I was approaching my question from the standpoint of having heard the term "DCC ready" and "analog" and did not know if one was exclusive or if there was a significant cost premium to have to add DCC and then a sound unit.
  For those of us who are not TOO critical yet, how much is the difference between the plug-n-play Tsunami units and the traditional units so far as sound quality. I'm thinking about the On30 2-4-4-2 and the Tsunami Plug-n-play unit. I have had, I think it's the SoundTraxx 100 (don't have it in front of me to be correct) installed and am quite pleased with the result, especially the sound of both sets of cylinders. I do have an issue regarding the water fill. On my basic Bachmann controller, I can satisfactorily access options 1-5 and the generator and light on 10, but not the water fill option. It was put in by an authorized installer. I plan to give SoundTraxx a call, but since I'm typing....

I have a chance to purchase a nicely detailed analog mogul. What is involved to add DCC and Sound. Do I need both a DCC decoder and a SoundTraxx unit or is there a unit that combines both?

Wondered what it was for, never would have guessed this was its purpose. Makes sense when you think about it.
My tapered stack had no hole; a little work with the drill solved that. But I'll bet I'd never have found the hole in the cab without some guidance. And I agree, it took a bit of fiddling to work the line through the hand rail etc.
Thanks for the help, guys, and information. Great site Bachmann has here.

Thanks for the information. I figured it was something like that. I'll have to check again, but I was sure I saw no mounting hole in the stack. If I have to order a replacement I'll be certain to ask them to make sure it has the mounting hole. Jon

Not very technologically savvy so I hope I can explain this.
I have replaced the cabbage head stack with the tapered stack option on my 2-8-0. The parts diagram shows what I surmise is an air or steam line running from the fireman's side of the cab along the boiler and up the stack (to generate updraft?). Can't figure out where it fastens at either end. The projection near the top of the line appears to bear on the side of the stack as if there should be a receptacle on the stack for it to fit into, which there isn't. What keeps it in place?
  You folks have been most helpful in the past so I anticipate you'll straighten me out again.

But it's a diesel! For us steamies, that's about as much fun as a date with an inflateable doll....

Rich - thanks for the lead on Privatelee.grobe.it  Was not aware of it. Jon

 Thanks, I had looked all over trying to discover just what it referred to. The link to Wikipedia was most helpful, even if a bit obscure to someone who has begun having difficulty getting his socks on the right feet in the morning.... Jon

Will someone please explain to me what "CV" stands for?  Thanks. Jon

I am looking for appropriate spark arrestors for On30 straight or tapered stacks. Somewhere I heard Bachmann included them in Forney accessories. I have been able to find ONE on line. Sources would be appreciated. Thanks.

I, too find myself rather disappointed at what Bachmann has done, or, more correctly, not done.
When I popped the coal load off my new 2-6-6-2 there it was: a 21 pin decoder. Great, I thought, now all I have to do is purchase a Tsunami decoder and plug it in.
  I checked the Soundtraxx site and found they have a compatible decoder for the 2-4-4-2, but none listed for the 2-6-6-2. I figured, perhaps the 2-4-4-2 would be compatible since both are articulated locomotives and the sound should be at least compatible if not the same. No so.
The folks at Soundtraxx told me they do NOT have a Tsunami unit for the 2-6-6-2. And Bachmann confirmed there is none compatible for the 2-6-6-2 and I would have to install a regular Soundtraxx unit. They shared the plug and play Tsunami unit is installed in the engines when they leave China, but no aftermarket plug and play unit is available.
  The logic of this completely escapes me and it seems to me Bachmann has dropped the ball and made a major mistake. Was someone in the Bachmann sound department on vacation when the decision was made?
  I have come to expect more from Bachmann and am EXTREMELY disappointed. Jon

Thanks for the help, guys. The 2-8-0 is at my deale'rs awaiting the hand of a master installer. Since I'm old and have been having difficulty getting my socks on the right feet in the morning lately I thought this was the best alternative....  Jon

Does the On30 2-6-6-2 use the same plug and play Tsunami sound unit as the 2-4-4-2?

Have not been successful figuring out what I need from the Bachmann site to add aftermarket sound to my On30 DCC Consolidation.  Please advise. Also, can't find the uncoupling magnet for under track installation.

Thanks, Jon O.
