Why does my train always go from the furthest platforms at Marylebone when platforms 1, 2 & 3 are free?

Each day we have a schedule of which platforms our trains are due to arrive into/depart from. Although platforms may appear to be free, platforms are selected based upon us delivering the most punctual and frequent service we can.

We try to use boarding zone ‘A’ when we can, this is located near to platforms 4, 5 & 6. This means that passengers are closer to platforms 4, 5 & 6 when their train is announced and they can board the service with a comfortable amount of time before its scheduled departure.
