With over 1000 units sold, the Vectron is one of the most successful rail vehicles ever built. It can now be found all over Europe, and the routes are getting longer. Slovakian and Swiss Vectrons meet in the heart of the Ruhr area, and ÖBB is expanding its network into the Netherlands and Belgium. Almost every day, new variants are added, and the Vectron has also found a home in Serbia and Bulgaria. The cost-effective Siemens Smartron is also gaining popularity. Many operators are competing for the favor of customers and trainspotters with increasingly elaborate and eye-catching designs.
