To secure you able to create the QR code without panic, my idea.
1. Create 2 different time in planner and save to my trip.
2. Activate the train time that suit your schedule when you reach train station or Activate the QR for the specific train before get in to that train.
Not rushing, if you run out of time, you still can create the above same method with new internally.
