Technical
Except the turbine and transmission modifications the Class 210 are basically identical to the DB Class 218; They have the same 12-cylinder engine from MTU of type MA 12 V 956 TB 10, and the same electrical system and roughly the same chassis.
The Class 210 was however geared for a higher maximum speed of 160 km/h and therefore had an additional hydrodynamic brake as well. For the same reason modifications to the drive shaft were made as well as an increased brake pad.
Since the gas turbines optimum performance was at a speed of 19250 rpm, the output was geared down to 6000 rpm for the hydraulic drive. The main diesel and gas turbine (as in the Class 219 001) had two independent drive shafts with the output connected by gears. Each hydraulic chamber could be filled and emptied independently.
The turbine was based on a 845 kilowatt design but was throttled back in order to prevent damage to the other components. The main power was supplied by the diesel - the gas turbine was either on or off, or on idle mode. The chimney like exhaust for the turbine on the locomotive roof was the main distinguishing feature between a Class 210 and similar but conventionally powered locomotives such as the Class 218.

Famous quotes containing the word technical:
“In effect, to follow, not to force the public inclination; to give a direction, a form, a technical dress, and a specific sanction, to the general sense of the community, is the true end of legislature.”
—Edmund Burke (1729–1797)
“The best work of artists in any age is the work of innocence liberated by technical knowledge. The laboratory experiments that led to the theory of pure color equipped the impressionists to paint nature as if it had only just been created.”
—Nancy Hale (b. 1908)
“Woman is the future of man. That means that the world which was once formed in man’s image will now be transformed to the image of woman. The more technical and mechanical, cold and metallic it becomes, the more it will need the kind of warmth that only the woman can give it. If we want to save the world, we must adapt to the woman, let ourselves be led by the woman, let ourselves be penetrated by the Ewigweiblich, the eternally feminine!”
—Milan Kundera (b. 1929)
