    Question Atlas S-2 DCC Ready TSU-1100 Decoder/Speaker Installation?

    I missed out on the B&O DCC/Sound S-2s. I was going to buy a Penn Central or Soo line (vertical shutters) DCC/sound version and paint it in the B&O livery colors. Last week, I came across a B&O DCC ready version on e-bay. I would rather convert the DCC ready version than paint one on the proper livery so I bought it.

    It runs great, smooth and quiet. It will pull twelve 40' box cars through a 15" radius without wheel slippage.

    I'm pretty confident about being able to fit the Tsunami TSU-1100 decoder, but I'm a bit concerned about where to accommodate the speaker. The smallest I can find are either the Lok-Sound 50321 15mm x 11mm, Lok-Sound 50326 14mm x 12mm or the Soundtraxx 810155 13mm x 9mm. My concern with the 810155 is the 9.4mm depth. I have some Lok-sound 50326 speakers in hand for another project so I can try the fit on those.

    Does anyone know where the OEM speaker is mounted in the DCC/sound version? Perhaps someone has an exploded parts drawing or can post a link to one?

    The speaker on the DCC-Sound versions is in the enclosure on the right side -



    I believe the DCC-Ready versions have the same enclosure (just sans the speaker) -

    That's what I was thinking when I saw the picture on your page. BTW, your page at the top of my bookmarks page.

    Does the enclosure just pry off?

    I'd think so, although I have never tried.

    Parts diagram shows it as a separate part and no screws or anything like that. Probably just clips on.

    I've read that the cab can be a chore to get off. Any experience with that?

    It's not too difficult. You just disconnect the handrails and end-railings and then sort of rock the cab back and forth (side-to-side) until it disengages from the chassis.

    Thanks, I'll be dismantling the locomotive sometime in the next week to measure the space available for a sugar cube speaker. Any experience as far as the sound quality for the ESU 50321 15mm x 11mm or 50326 14mm x 12mm speakers? I have some 50326 speakers in hand for another project so I can try the fit of one of those.

    I, however, found the cab a right PITA to remove.

    What helped was chanting a lot of old railroady words that I can't share here. Somewhere I must have stumbled upon the right phrase because the cab then slipped off as advertised.
