What does three long buzzers from the conductor indicate?

Three long buzzers from the conductor signal a stop at the next station or employee stop. This communication method is essential for ensuring that both the crew and passengers are aware of upcoming changes in the train's operation. The use of multiple buzzers indicates that this is an important action that needs immediate attention, typically employed when the train is approaching a designated stop where a halt is necessary to either allow passengers to board or disembark or to facilitate an employee activity. This signaling helps maintain the safety and efficiency of train operations, ensuring that stops are made at the correct location as per the scheduled timetable or operational requirement.
