I believe I have the most recent photos of both...

4973 on December 21st 2012, unusually working "Fab Fifty Six" service 56 to Newcastle.
4974 during the Boxing Day madness, working "MetroLink" service M1 to Houghton-le-Spring.

If they are being refurbished, that answers a previous question of mine as to why allocations have gone to pot! To cover for the two missing vehicles, other Scanias are being used on the X35, causing those services to be without the necessary amount of vehicles required for the service, resulting in odd allocations. A month is a bit excessive though, surely?
