If you get a chance to visit a giant miniature railway like this, do so. They are marvelously complicated pieces of machinery combined with hand crafted works of art to build the city and scenery on top.<p>And if you get a chance to peek in the control room to see what makes these things tick, take it. I took a peek to a control room of a much smaller railway set than the one in the article and it was impressive. About a few dozen monitors that display the entire track network and every train and vehicle on the tracks.<p>The railway I visited was in Berlin, on the top floor of a mall in Alexanderplatz. It&#x27;s the biggest miniature railway I&#x27;ve ever seen, but it&#x27;s smaller than the one in the article.
