Between 1974 and 1976, the Spanish RENFE procured a total of 93 D333 diesel locomotives to run heavy express trains on non-electrified main routes. The diesel-electric locomotive, manufactured by NoHAB under an EMD license, has an output of 2500 kW and originally reached a maximum speed of 146 km/h. The EMD sixteen-cylinder diesel prime mover generated the energy for the six electric traction motors. In the 1990s, the locomotives were adapted to various fields of application and some of them were extensively converted. Eight machines were given new bogies for 160 km/h (333.1 series), and the four specimens with modified transmissions for 140 km/h were known as Class 333.2. 92 examples were radically modernized from 2000 with a new locomotive body, new drive motors and electronic motor control. In favor of a higher tractive effort in freight train service, the type now known as 333.3 was limited to 120 km/h. Eight of the converted machines were designed for a top speed of 140 km/h and have since been used again to pull passenger trains. Different starting processes can be selected with F1: 1x press button = warm start / press button 2x = false start / press button 3x = cold start
F5 enables the heavy load mode: The diesel notch is always one up compared with normal operation. If you want to jump two notches, simply set CV 104 to 170 (instead of 150).
F27 turns on the manual ntoching. Once F28 is on, you can use F28 to notch up and F29 to notch down. F27, F28, and F29 must be turned off to return to normal mode. If F27 is off and you press F28, the prime mover will run to full speed.
F17 will bring the locomotive to full stop.
