I have three older G gauge trains I want to convert to battery power from 1992, 1994, 1995. Item numbers in order 90015, 90022, 90025. Does anyone have parts list and wiring diagram for these units? Also if you have converted an older G gauge do you have a parts list? I am thinking about using Soundtraxx is this good?

Thanks,

Paule

did you check first to see if the wiring diagrams are on the Bachmann site?
