Introduction
The report discusses the application of the Omnitrac laser tracker by Automated Precision Europe GmbH in the locomotive industry, specifically at Siemens Lokomotivenwerk Munich. Siemens is known for its efficient and environmentally friendly locomotives, including the Vectron generation, which offers flexibility for various applications.

Car Body Construction
The locomotive car body is a self-supporting structure comprising the underframe, driver's cab, and engine room side panels. These components are manufactured using folded, lasered, or drilled steel plates, assembled in jigs, and welded together. Robotic welding systems are employed, and precise measurements are crucial for ensuring quality.

Transition to Laser Trackers
Previously, Siemens used tachymeters for measurements, but the need for increased measurement capacity led to the adoption of laser trackers. The Omnitrac laser trackers from API were chosen for their efficiency and ability to automate measurement processes, reducing the need for external services and allowing for self-programming of measurement tasks.

Advantages of Laser Trackers
The laser trackers offer significant time savings and accuracy improvements. They allow for single-person operation and can perform special measurements, such as free clearance profiles and jig checks. The compact design enables installation under the underframe, saving measurement time and increasing flexibility.

Implementation and Flexibility
The laser trackers are portable and can be easily moved between different factory locations. They are used for demonstrations to customers, showcasing process reliability and measurement accuracy. The switch to laser trackers has resulted in cost savings and independence from external service providers.

Conclusion
Thomas Osterauer, Quality Manager at Siemens, confirms the success of replacing tachymeters with laser trackers, highlighting improved accuracy, speed, and cost-effectiveness. The Munich factory has produced over 21,000 locomotives, with a focus on steel construction, assembly, and component development.
