At DB Fernverkehr, we are running some IT Infrastructure on a large fleet of ICE Trains. In the past, there was only WIFI for the passengers, and many systems were handled as “embedded systems”. Nowadays, more aspects of “modern IT infrastructure” are part of the IT in trains, providing additional services like passenger information. This talk gives a quick introduction of what is happening on the trains, as well as some of the challenges compared to infrastructure built in data centers: How to get proper internet on the train? How can a network look like? What is the difference to the data center with regards to hardware selection and lifecycle? Do we even have racks? And most importantly: Why can’t we just model a train in netbox? Licensed to the public under http://creativecommons.org/licenses/by/4.0 about this event: https://pretalx.com/denog17/talk/K3HSNK/
