The DB Class 240 are a class of Co'Co' diesel-electric locomotives which were produced in the 1980s by MaK in collaboration with Krupp and ABB as DE 1024 as prototypes/technology demonstrators for a possible future order from the Deutsche Bundesbahn.Three units were made, but no orders arose, at least in part to the Reunification of Germany making similarly specified DR Class 132s available in large numbers.
