I have 3 older Williams GG1' s with "horn" only and would like to upgrad these to correct GG1 horn. Any suggestions? Will the new Bachmann Williams GG1 sound be able to be added?

I would imagine that you could find sound kits, from '3rd party' companies, such as QS Industries: http://qsindustries.com/, or Electric Railroad Co.: http://www.electricrr.com/, or Dallee Electronics: https://www.dallee.com/.
Hope this helps.
