The ATT range was short-lived; the models first appeared in 1967 and by 1970 ATT had ceased trading. The closure of ATT was not the end of the line, though, for the Roco manufactured range of freight cars. In many ways, the true successor to ATT was
Parkway Industries Co. of Cleveland, Ohio who continued to import the Roco freight cars, repackage and market them as sets and individual models under their own name between circa 1971 and 1974.
ATT Roco Freight Cars can also be found in Precision Miniatures packaging (circa 1971-1972); these are surplus ATT stock which was purchased by PMI Products (Model Power) after ATT had ceased trading - see A Brief History of ATT for more information.
Former ATT Roco Freight Cars can also be found in the later AHM range of models, which included many newer liveries that were applied to the former ATT models.
