Prior to the Onboard Data Centre, traditional train technology companies such as Nomad Digital have been installing connectivity hardware on-board. An example of such technology would be the antennas installed on the train’s roof, modems installed (CCU) and writing code with the sole purpose of providing passengers with WiFi. The problem is every application added to the train possesses similarities, whether this is obtaining its own hardware or discrete network – increasing the quantity of connectivity hardware on-board.
As a direct result, the train operator ends up with lots of discrete requirements and equipment which can’t communicate with one another. In effect, this can prove difficult to maintain due to the lack of space on a train, the out of service hours and just the sheer amount of hardware! The main problem is all applications are running from one programme, in effect if one application breaks and needs repaired – all applications will be offline!
