For many years now, double-decker trains have successfully formed the backbone of regional traffic. Double-decker trains are the ideal solution, especially on routes with low platform lengths and a high volume of passengers. The tried-and-tested single-wagon concept of the TWINDEXX Vario double-decker fleet was supplemented with an electrical railcar. The four-part railcars from the "Do 2010" generation consist of 2 railcars and 2 middle wagons respectively. With the driven TWINDEXX Vario railcar, it is now possible to utilise the trains as pure double-decker multiple unit trains. As a result, it is also possible to use this vehicle as an electric multiple unit train alongside the classic push-pull operation with an electric or diesel locomotive. This railcar can be combined with middle wagons and control cars depending upon the application and desired capacity. The central buffer coupling enables operation with double traction and, as a result, the implementation of a wing-train concept. The trains with a combined upper and lower entrance are comfortably equipped with generous seat spacing and plenty of storage space. Furthermore, the double-decker individual wagons permit the extension and shortening of the block train and, consequently, an adjustment to fluctuating demand or future development. As a result, they can be utilised for the most diverse of operational applications in both regional and long-distance traffic.
