Digital Electronic Modules for Command and Control of Miniature Railway Systems

Modern miniature trains, also known as "model trains", are now designed and built by means of state-of-the-art mechanical and electrical technologies and require special care for handling and operation. Therefore, they must be considered as miniature robots and treated accordingly. Digital electronic modules have become very useful to supply power to the miniature railway systems, to provide commands and to ensure adequate safety and control. This paper presents several such digital electronic modules, which were built and used by the author for the operation of his miniature trains collection.
