This leads to an utterly pointless cacophony. Instead they should close silently. The chime is only useful when the reason the doors are closing is because they are changing to “closed, ready to move” mode. Arguably the chime should also sound just before the doors switch from “ open when button pressed” mode to “closed, ready to move” mode.
Additionally, the doors should have different re-opening policies depending on why they’re closing: if they’re closing because enough time has elapsed since the button was pushed, they should re-open like an elevator door: essentially, prioritize letting people through. Only once the doors have been informed to close in preparation for departure should they switch to the more aggressive subway train policy which prioritizes getting the train under way (and then, of course, see previous discussion on allowing each door to have more independence).
Is this not an accessibility feature to let all people know that the door is closing? I.e., it is about the door closing, not the train departing.
