Early electronic interlocking systems were designed according to 1980’s state of the art in information technology. Accessing diagnostic data to look under the bonnet of the interlocking would be cumbersome. Today’s “Internet of Things” premise is to expose state data of sensor-equipped objects in the field. This paper explains how one can make a 1990’s interlocking look like an IoT system. Authorised users can select and observe live state data from objects controlled by the interlocking, in IoT style. What’s more, one can create a “digital mirror” of the interlocking system by providing rich data that represent both static configuration data and dynamic state data of the running system.
