Hi,
     Back into model railroading after 60+ years.  Dusted off my old Lionels and celebrated with a
new scale Williams GG1 purchase.  I have an old Lionel ZW 250watt transformer.  Can I run my
new GG1 on the same track with the ZW with my old equipment?  Or, do I need to purchase an
AC transformer and run the GG1 and any new items on separate track.  Its been so long, I'm assuming
my old ZW converts the AC to DC to power the track.  Its still packed up in the attic somewhere so I
can't look at it just yet.

         Thanks
              Tony
