"The Waggonbau Görlitz Corporation (Görlitz Rolling Stock Corporation) has built locomotives and rolling stock since 1849. They are best known for the double-deck rail cars that have been in production since 1935 in Görlitz, Germany. The Görlitz plants have been sold to Bombardier Transportation in 1998 making them available under the Bombardier Double-deck Coach brand (not to be confused with the North-American Bombardier BiLevel Coaches)." - (en.wikipedia.org 06.04.2021)
