By the late 80's, double stack trains had become the standard method for moving international 20' and 40' containers. But 48' containers for domestic service were becoming more common and that presented a problem for railroads. The Twinstacks, Lo-Pac 2000's and Maxi-Stacks could only carry 48' containers in the upper position. If the domestic boxes outnumbered the international boxes, the extras would be left behind. Then in 1989, Gunderson introduced the Maxi-Stack III. This articulated car featured five 48' wells, Each well could carry 20', 24', 40', 45', or 48' containers in the bottom position and 40', 45', 48', or 53' containers in the upper position. The Maxi-III was an immediate hit with the intermodal community.
