While driving a Little Test-Run on Köln-Aachen using the Scenario-Editor and the BR185.2 from RSN Preserved I noticed that the PZB allways runs in the M-Mode; It does not matter wether you selected U-, M-, or O-Mode. I´ve noticed this while trying to reach the Maximum Permitted Speed of the Loco (140 kph). The PZB triggers an Overspeed-Warning at 125 and a Emergency-Brake application at ~130 kph. This happens regardless of the Mode under which the PZB is running. In this case, the PZB was set to O-Mode.
