Eureka!
I think I have solved the mystery (to me anyway) of the 'rogue' directional indicators on the marker posts.
I have found an excellent document which shows that there is a spur from Thameside aka Coryton to Buncefield, whilst the remainder of the pipeline continues to Kingsbury. Therefore when you are looking at the pipeline spur, then the arrows are going to point towards Buncefield. Whilst not on the spur the directional indicator whilst the remainder of the arrows are going to point away from the Buncefield terminal.
This would mean that the 'T'-junction spur will occur between the two marker posts with different directions on. The diagram below shows it well. Now just to locate the line coming in from the east and to work out where the spur is.
