In the 2000s intermodal containers came in a large variety of shapes and sizes. Common containers in that time ranged from 20’, 28’, 40’, 45’,48’ and 53’. This much variety was deemed inefficient by railroads and trucking companies alike in the early part of this decade. Today the most common containers are either20’, 40’ and 53’. With the phasing out of the once popular 48’ containers, TTX had little need for their 48’ well cars. These cars were still rather new, most built in the mid to late 1990s. So instead of scrapping cars that were in serviceable condition, TTX opted to start a rebuilding program in which the 48’ well cars were shortened to 40’s and/or lengthened to 53’s.
