Probably more appropriate for the 'Other Ways to Travel' board, but it seems that SWT▸ ran an additional service non-stop from Reading to Waterloo at 0754 this morning. (Real Time Trains shows actual departure time of 0803 with arrival at WAT at 0915, still a 72-minute journey though.)
This morning, the same train looked pretty empty, and I think it stopped at Wokingham. The only announcement I can find is in SWT's "Other train service updates" section of their "Live train information" page:
07:54 Reading to London Waterloo due 09:18
An additional train service has been planned to operate as shown 12/02/14 07:54 Reading to London Waterloo due 09:18.
This is due to flooding.

That's quaintly worded, and you'd only find it if you were looking for it. Has it had any other publicity - particularly from the
FGW▸ side, if it's really a kind of replacement service? I guess at Reading is the obvious place, as in principle it's non-stop. (Though it's now shown as stopping at Bracknell, Ascot, and Sunningdale - but not Staines, which is odd as it's really a 'repurposed' Windsor train.)
I was going to ask what if anything was being done (or could be) to augment the FGW Windsor service, which is shown as an alternative by SWT, since there are spare paths to London there too. However, I thinks that's just been answered.
