Ward Amtran School Bus 3D Model

American Transportation Corporation (better known as AmTran) was an American manufacturer of school bus bodies. Tracing its roots to Ward Body Works (established in 1933), AmTran was formed in 1980 following the 1979 bankruptcy of Ward to continue bus production. In 1991, the company became a subsidiary of Navistar International, leading to a series of acquisitions of school bus body manufacturers by chassis suppliers during the 1990s.

As with its predecessor company, AmTran corporate headquarters and manufacturing facilities were located in Conway, Arkansas. In 1999, the company opened an assembly facility in Tulsa, Oklahoma.

In 2000, Navistar rebranded AmTran as part of International Truck and Bus, with vehicles taking on International branding. During 2002, the branding changed again, as the name was changed to IC Corporation (IC Bus since 2008).
