I worked on the Olympic Park line construction job - it’s a flying junction at the north fork, near the former Pippita platform location, and it is also grade separated from the freight line. When the job started the old flat junctions for the Pippita/Abbotoirs line were to be retained, but the volume of freight traffic through the area forced a redesign to include grade separation. The dive for freight trains is quite steep and prone to flooding, despite having floodwater pumps.

Likewise, from the very diagram which Tony cited, on 2 min track headways, a train can have a 3 min platform headway, and back to a quite achievable 60 000 per hour.
