Why Clock Alarms Are Unreliable on Long Rail Journeys
Assume scheduled arrival at Nagpur Junction is 03:45 AM, and you set a smartphone alarm for 03:20 AM:
- If the train is delayed: Running two hours late due to fog, the alarm rings at 03:20 AM while you are still 120 kilometers away, unnecessarily waking you up.
- If the train makes up time: Operating on clear tracks overnight, the train pulls in at 03:15 AM before your clock alarm triggers, risking an overshoot of your stop.
How Distance-Based GPS Alarms Function
Instead of referencing the phone's internal clock, RailTrack uses geographic perimeter boundaries:
- Select your destination station (e.g., Kota Jn or Surat).
- Tap the station alarm bell icon.
- The application monitors progress against track kilometer markers using cell-tower and GPS sensors.
- When crossing the 10 km boundary (or your customized buffer), the alarm sounds with high-priority audio and vibration until dismissed.
