Can PS 3 sound sets be installed in PS 2 engines

No.  Look up your model and see if MTH shows an updated sound file.  You can go in the other direction and put a PS2 file in a PS3 locomotive.

Marty, if there is an updated sound file, how can you download it to your engine?  Excuse my ignorance as I don't own any MTH engines but will soon (which is why I ask).  Or would you just replace the sound board alltogethor?

MTH has available (free) a Loader Program that runs on a PC. That is what is used to transfer sound files for PS2 engines, and sound and chain files for PS3 engines. You can obtain the Loader Program and instructions for its use on MTH's Protosound2.com web site.

Even better instructions for using the Loader Program are included in The DCS Companion 3rd Edition.

This and a whole lot more is all in “The DCS Companion 3rd Edition!" This book is available from many fine OGR advertisers and forum sponsors, or as an eBook or a printed book at MTH's web store!

Actually the answer is a qualified maybe.  It's not officially supported but read this persons web page carefully on the topic and you may find a path to changing specific clips in the sound files using the software he provides -- but just to be clear --  not entire PS2 or PS3 files but specific sound clips in them.  

I would contact the author directly for further help or more detailed questions, etc...
