Okay so this system is some sort of extra information box for platform staff to see what is going on.
It's probably fed from the Open Data feeds which also feed a bunch of Web services such as open train times and real time trains et al.
It will be running on a standard COTS IT system used for office staff hence the 365 install.
It has no access to safety critical or safety relates systems.
I'm not bragging (I'm really not) but I have worked in and around railway signalling and control for a decade and look at this stuff a lot.
It's done as cheap and quickly as possible to get info to people on the front line. The thinking required to build a cut down box running a custom OS running some neat pure code which is optimised is vastly outweighed by the fact a windows box is £40 a month on internal lease and will be binned off in 5 years when it all gets changed anyway.
Biting the hand that feeds IT
