Can “Brand X” track be combined with “Brand Y” track?
Yes and No. Each brand of HO slot car track has its own proprietary connector system, but track adapters are available to connect different track systems. Here again Tomy offers the best variety of track sections, so converting a Life-Like or Tyco/Mattel track to the Tomy Track System is your best bet. See the Track section for a complete discussion of the various track systems available.
