This amazing model railroad layout in Berlin, Germany, with more than 9,000 square feet of floor space, was the world's third largest model railway exhibit. It opened on September 18, 2004 in Berlin, later it moved to the Alexa Shopping Center in 2007. Note, the last opening day was August 31, 2017. At the beginning, 70 employees constructed this model railroad with a size of 6,000 square feet of floor space. Thereafter, the railroad display was taken down, moved and rebuilt in the new shopping mall. When the model train show was re-opened, the display was expanded to more than 9,000 square feet of floor space. A large part of the model railroad presented places and buildings in Berlin. In addition, there were Berlin’s famous railway stations and sections of the famous Berlin Underground, also known as Berlin Metro or Berlin Subway. Also attractions such as the zoo, the television tower, the Reichstag and the Brandenburg Gate were presented. However, the model railroad layout was not a complete model of the city. The display was built in HO scale and included over 13,000 feet of railway tracks and 32,800 cars and much more. The model trains, made by Fleischmann, Roco, Brawa, Gützold and Piko, were digitally controlled. For example, 30 computers and 80 cameras monitored the railway traffic. In addition to the trains, there were also model cars on the run using a system similar to the Faller Car System. Every 20 minutes there was night, so the lights of the houses became visible. Sorry, but during the night Pilentum could not take video recordings. In total, 30,000 LED were installed in trains, in cars and in buildings.
