Design and Modifications
The locomotive has a diesel powertrain, using hydraulic transmission, with both bogies driven by cardan shafts, and all wheels powered.
The ten initial prototype machines built from 1968-1969 by Krupp were powered by diesel engines of type 12 V 956 TB 10 with a power of 1839 kW.
The machines numbered 215 011 to 215 070, and 215 094 to 215 150 had less powerful (1397 kW) but more reliable 16-cylinder Maybach MTU 16 V 652 TB engines (the same as the engines with which the Class 216 / V 160s were equipped), while the numbers 215 071 to 215 093 had a more powerful engine, but this time again the 12-cylinder 12 V 956 TB used in the prototypes. 215 091 to 215 093 were later retrofitted with the V-12 engine, having initially had the 16-cylinder engine.
The steam heating also doubled as a pre-heater for the locomotives engine, and other parts. Space was reserved for the installation of an electrical generator later on, the proposed conversion of the machines to the 218 series never came about - the exception was 215 112 which was rebuilt as DB Class 218 399 after an accident.
Numbers 030 to 032 locos were exceptional in that they were fitted from the outset with an electric heater (steam heating was removed) driven from an auxiliary diesel of type 8V 331 TC 10 with an output of 520 kW at 2100 rpm. Unlike in the DB Class 217 the auxiliary diesel is not connected to the transmission and cannot be used for additional traction power

Famous quotes containing the word design:
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
