Some of the 20th century’s most iconic design and typography came to us through public signage in the various national railways of Europe. Were you to think of a Modernist clock face for example, the chances are that the prototype for your image hangs somewhere in one of the continent’s great railway terminals. If you don’t fancy getting on a train to see your favourite public timepiece, then maybe [EBP Controller] has a treat for you, with a 3D-printed double-faced Belgian railway station clock.

Behind the scenes the mechanism is simpler than appearances might lead the observer to believe, with each set of hands driven through a single gear to a motor. Controlling it all is an ESP8266, which is able to synchronise the clock exactly to an NTP server. It appears at first sight to have an unnecessarily large quantity of motors, but considering that there are two faces each with three hands the six motors each have a use. So while the real thing might require a heist from the SNCB, at least modernist clock fans can now have their own.
