Ztrack Center is offering two new sets of mixed AZL high-cubes! These sets are not an 'official' AZL release, but a mix of AZL's existing high-cube set! The first new set is a 4 pack comprising 2 of AZL's CP high-cubes and 2 of the BNSF high-cubes. This set compliments the previously mixed set of 2 TTX high-cubes and 2 UP high-cubes. For those looking for only one car of each road name, Ztrack Center is offering a 4 pack mix of high-cubes. This set contains one each of the TTX, BNSF, CP and UP high-cubes! Of course, runner packs are still available! To order, please visit: Ztrack Center Rob Kluz
