The diesel locomotive V100 of the Deutsche Bundesbahn (DB) had been developed in the late 1950s to replace the Prussian steam locos BR 38.10-40, BR 55 and 78. The locos had 12 cylinder four stroke motors with 1100 HP of MAN, Mercedes-Benz or Maybach. A pair of those motors also worked in the famous V200. The DB found out that the motors were not strong enough for some service so the DB ordered a stronger version of the V100.10 (later numbered as BR 211) named V100.20 (later BR 212). The 212 had a larger cooling system in the long hood and were slightly longer than the 211. They were powered by 1350 HP diesel motors of Mercedes-Benz or MAN. If a motor change had been necessary the motors had been replaced by MTU’s MB 12 V 652 TA. Both V100 types had been equipped with a 2 cyl. diesel motor to develop the electrical energy for the loco while the main diesel motor had not been working. The locos had a horn and a bell.
