    In a fully ERTMS Level 2 area, if you lose GSM-R you lose both signalling and communications to/from the trains - so all trains stopped, which is not very safe. So is denial of service a bigger risk than risk of bogus messages?


    I would argue stopping all trains is a safe move. Denial of Service is a problem because it has economic effects - e.g. stopping trains at a throat to a major station.
