Lionel Area 51 lit Fastrack question.

Hi GUYZ,

  I recently picked up the Lionel Area 51 set with lit fastrack.  It runs great and looks great too.  I want to get more of the alien green fastrack, but can’t find any of the add on packs yet. My question is can I add on regular fastrack and run it with the lit track being powered with a 80 watt transformer instead of the 72 wall wart that came with the set?  Running it with the 80 watt transformer will it effect the LEDs in the fastrack?  Thanks for your time.
