Equipment do cost money, but I wounder how much a day of closure also cost?
As for Oslo, the "snowtrain" is at max about 60 vehicles..if I remember correct. Just one sweep along the runway and taxiway and all is cleaned, swept, sanded/threated with chemicals and measured.
For sure our layout is better suited for keeping the airport operational (atleast until they build the new terminal), with less taxiways and terminals.
I suggest someone show the bosses this link
