DB Class V 169
The DB Class V 169 consisted of a single example: V 169 001, derived from the DB Class V 160 family, with an additional gas turbine booster engine. It can be considered the prototype for diesel locomotives with a gas turbine as an additional drive; specifically the DB Class 210. Post 1968 the class designation was changed to Class 219, and the locomotive renumbered 219 001 In 1999 the locomotive was heavily renovated for a private company, and does not now have the gas turbine. Post the merger of the Deutsche Bundesbahn and Deutsche Reichsbahn another locomotive - the DR Class 119 has been assigned to the DB class 219. Background From 1963 onwards the DB Class V 160 had been delivered and deployed in large numbers, and was proving successful. Thus plans were made for testing of further units were made - specifically a variant with electric train heating. These units would require more power than the engines installed in the V 160 could deliver. Three prototype units of the DB Class V 162 (later Class 217) were ordered; with the addition of a smaller supplementary diesel engine, providing via a generator the electricity for electric train supply.
