No - I read the Train Driver briefing notes.
No doubt when the Feeder lines are commissioned there'll be a correction briefed out by then.
Just to throw in another opinion, there is definitely a naming/definition error here.
No matter what you do at Oxford Road Junction can't get you to the Festival Line other than by doing a reversal in P3, 7 or 8.
The
NR» Network Change Notice reads
Re-modelling of Oxford Road Junction and installation and renewal of a number of point ends to support the future introduction of the new Up Reading Feeder Main Line and Down Reading Feeder Relief Line.
The word "Festival" does not appear in that document.
Just looks like the word "Festival" has been incorrectly used instead "Feeder" in the Driver Briefing notes.
