Yesterday was extremely slippery on the tracks. I almost went out a station, just barely managed to hold it. Had to use the emergency brake button to make the final stop. If you use it too early it does nothing and you will just keep sliding. Was a bit stressful. Later I heard the two guys before me did slip out of the station. They had to inform the passengers who were going there to get out at the next station and take the next træen back
