The SET extension set program is a progressive system with which you can expand track layouts from the starter sets in steps. The E 8190 or E 8191 is used to expand the 81530/81535 or 81562 set. You can then systematically expand in any sequence desired with the T1 8192, T2 8193 and T3 8194 track extension sets.
