DCC Bachmann Locomotives: Converting to DCC Sound?

[dpffitz]

I have about a dozen Bachmann DCC Locomotives that I want to add Sound.
I'm having a heck of a time identifying my Locomotive so I can purchase the correct Sound equiptment.  Also, several of my Locomotives appear not to have screws in order to remove and gain access the engine compartment to see if it's DCC plug in ready.  I've tried gently prying on them to see if the top will come off but they are stuck fast.  Do we have to drill out the forward and aft posts that appear to be what's holding it together? Appreciate any suggestions your all might have. Dennis in Roswell GA

See the diagram of your locomotives to correct procedure to remove body. I added sound in my FT-A.

Knowing which locomotives you have would help a lot and pictures are worth 1000 words. You can upload pictures through Photobucket or Flickr as they cannot be attached if you want.
