The last service run on b600 will be tomorrow, Thursday, at 1600, after which the service will be replaced by an automation walkup on b400. If you haven’t been trained for this, or you are not scheduled for a training today, come to any of the trainings tomorrow, which are at 1000, 1300, 1400 and 1500. If you can’t make it tomorrow, you can ask for a training later.
