Extracted from the Wikipedia article Electro-Motive Diesel.
Electro-Motive Diesel traces its roots to the Electro-Motive Engineering Corporation, founded in 1922 and purchased by General Motors in 1930. After purchase by GM, the company was known as GM's Electro-Motive Division. In 2005, GM sold EMD to Greenbriar Equity Group and Berkshire Partners and, in 2010, EMD was sold to Progress Rail, a subsidiary of the heavy equipment manufacturer Caterpillar. After the 2005 sale, the company was renamed to Electro-Motive Diesel.
