How Germany's $4M Siemens Vectron Locomotive Is Built:Inside Factory Behind The Most Powerful Engine

This video takes viewers inside the Siemens Munich-Allach factory in Bavaria, Germany — one of Europe's most advanced locomotive manufacturing plants with nearly 190 years of history. Following the complete construction of the Vectron, a four-million-dollar, 90-tonne electric locomotive capable of operating in 20 countries, the video documents every stage of the process from raw steel arriving from Austria all the way to a finished, certified machine ready for the rails. You'll see how specialized steel sheets are laser-cut and fabricated into the structural underframe, how body shell panels are welded and assembled, how bogies and traction motors are mounted, and how 20 kilometers of cable are routed and connected inside a single locomotive. The video also covers the installation of electrical systems, converters, pantographs, and the driver's cab, revealing the precision, craftsmanship, and engineering that goes into building one of the most capable and widely used locomotives in the world. With over 2,700 units ordered across more than 100 customers and a combined fleet distance exceeding 1.2 billion kilometers, the Vectron is a benchmark of modern railway engineering — and this is a front-row look at exactly how it gets built.
