The Diamant was an express train operated by the Deutsche Bundesbahn (DB), using different routes over the years. The name Diamant, Dutch for diamond, refers to the city of Antwerp, which is the European centre of diamond trade[1] and has a diamond district. The initial service started in 1962[2] as a first-class-only FernTriebwagen linking the West-German capital Bonn with Antwerp, using a class diesel multiple unit (DMU).
Trans Europ Express
The Diamant was upgraded to Trans Europ Express (TEE) on 30 May 1965.[3] The VT 08 was replaced by DB Class VT 11.5 DMUs formerly used in the TEE Helvetia
