The Adtranz-CAF EMU (also known as A-Train, CAF-Train or LAR-Train) is an electric multiple unit (EMU) train that operates on the MTR rapid transit railway system in Hong Kong. There are two variants, one used on the conventional Tung Chung line, and a more luxurious version used on the Airport Express. The vehicle interiors were designed for MTR by Jones Garrard (Tung Chung Line) and Design Triangle (Airport Express), while the vehicle exterior and driver's cab interior were designed in the UK by Design Triangle (the first two model building of these were made in Spain by Diara Design). These two variations are built jointly by Adtranz (acquired by Bombardier Transportation in 2001, then Alstom in 2021) and Construcciones y Auxiliar de Ferrocarriles (CAF) and manufactured in Spain in 1996-1997.
