Who is the intended audience for this announcement?

Attention, please, all passengers waiting on Platform C to board the 10:10 train to Ottawa. There has been a large buildup of snow on the tracks at the Lafleur junction. Crews are currently clearing the track, but the train has now been rescheduled to depart from the station at 12: 00. With regret, there will be a minimum of a 2-hour delay. This is necessary to ensure the safety of the passengers and crew at all times. Any passengers who are unable to wait are welcome to speak with a ticket agent to exchange their train ticket for a bus ticket instead. There will be no extra charge for this alternative service. Thank you for your understanding.
