Alan Turing, pioneiro da computação, e já abordado na PG po,r entre outras coisas, ter inventado a Turing Machine, máquina onde qualquer coisa pode em teoria ser calculada, serviu de base para uma interessante tradução efectuado por dois artistas Austríacos, David Moises e Severin Hofmann, num modelo de sistema ferroviário. A locomotiva do Turing Train Terminal, percorre uma rotina programada num fita que faz com que a primeira altere as suas cabeças de leitura/escrita [read&write heads]. Diferentes tipos de interruptores despoletam passos computacionais distintos.

Scale trains have existed for almost as long as their archetypes, which were developed for the purposes of traffic, transportation and trade. Economy and commerce have also been the underlying motivations for the invention of computers, calculators and artificial brains.
Allowing ourselves to fleetingly believe in an earlier historical miscalculation that "... Computers in the future may have only 1,000 vacuum tubes and perhaps weigh 1 1/2 tons." (Popular Mechanics, March 1949), we decided to put some hundred tons of scaled steel together in order to build these calculating protozoa. The operating system of this reckoning worm is the ultimate universal calculator, the Turingmachine, and is able to calculate whatever is capable ofbeing calculated. One just would have to continue building to see where this may lead...
