Quant developed the countdown in collaboration with Vialis Railway Signaling in the Netherlands, better known in the rail world as VRS.
This SIL1 safety product is installed on behalf of Prorail on platforms of train stations in the Netherlands and its purpose is to bring forward the departure procedure of the train so that adjacent level crossings do not have to remain closed unnecessarily long.
Below is a nice video that VRS made of the test days in which light output, climate tests, etc. are tested against the requirements of Prorail.
