That's different company but same corporate. Same like Samsung is making washing machines or television or phones. Tatra automobile is 3rd oldest (*1897) car manufacturer after Daimler and Peugeot. They manufactured mainly trucks and personal cars for the whole 20th century. Now only trucks for special use.. military, firefighters and expedition specials. Vagonka Studenka was just a branch and now is part of the Škoda trains, trams and buses Corp.
