In 1936, Englishman Alan M. Turing developed a computer, the so-called Turing machine.
This concept is now translated into a model railway. The locomotive runs through a program routine on a scratch tape and turns on read-write heads. Different types of switches trigger computational steps. Then the locomotive performs a readout of the scratch tape and displays a result. A train that can calculate.
