I've been looking at the info I have, my Anatomy of Warspite book has a large print of that photo of Warspite refuelling in '42, and it appears to me that there are no rails running perpendicular to the catapult into the hangars. There is something on the deck in front of the hangar, but it doesn't appear to be rails, it could be some sort of frame or even a ramp.
Incidentally my Ensign book of the Queen Elizabeth class has an aerial view of HMS Queen Elizabeth and plans, and she does have the rails and turntables into the hangars. This may be due to her being refitted a few years later than Warspite - a similar time to the construction of the early KGV class, perhaps this was a new development then.
I can scan and post excerpts on here (if the moderators will allow it) if anyone wants to see to decide for themselves.
