• Centrally mounted motor, 4 axles powered.
• Close couplers in standard pockets with a guide mechanism.
• mfx+ digital decoder.

Model:
The locomotive has an mfx+ digital decoder and extensive sound functions. It also has controlled high-efficiency propulsion. 4 axles powered. Traction tires. The triple headlights and dual red marker lights change over with the direction of travel, will work in conventional operation, and can be controlled digitally. Maintenance-free warm white and red LEDs are used for the lighting. The cab lighting can be controlled separately in digital operation. The cabs have interior details. The locomotive has close couplers in standard pockets with a guide mechanism. It also has separately applied grab irons. Length over the buffers 22.1 cm / 8-11/16".

Prototype information:
The Three-Phase Current Pioneer. The class 120 marked the technological change to three-phase current propulsion. This principle promised compact motors largely free of parts that would wear out, without commutators, commutator rings, brushes, and mechanical contacts. Because a wide torque range and rpm range can be mastered with three-phase current technology, the performance specifications for this new development were broadly formulated. The class 120 was designed to pull 200 km/h or 125 mph fast InterCity trains and 5,400 metric ton freight trains and be equipped with push/pull controls and electric regenerative brakes. In 1977, the DB ordered five experimental units, which were thoroughly tested on test stands, on test runs, and in operational use. Startup, tractive effort, acceleration, running characteristics, braking power, power consumption, and stability were part of these tests. Comparison tests with other makes of locomotives as well as startup tests on the Lötschberg and Semmering grades confirmed the effectiveness of the technology. The speed record was 265 km/h or 165 mph. During the test phase, new developments were introduced, for example: microprocessors for faster monitoring and control. Components were constantly improved until all five units were technically at the same level in 1982 and were ready for regular production. During the several years of development, the purchasing policy changed, however. Instead of all-round locomotives, special locomotives were once again preferred on the basis of common development platforms with many parts in common. Therefore, only the first production run of 60 units of the class 120 were purchased. The five prototypes continue to be used for test purposes, and the regular production locomotives are still proving themselves in daily railroad operations.
