Riverside station exit

Windsor is blessed with two beautiful railway stations. Riverside links Windsor with Waterloo. Along the south side there is a series of arched exits with views onto the Castle.
I went to the Riverside station as it was the meeting point for a walk as part of the Windsor Festival. Alas the guides didn't turn up and so we all went away disappointed. At the same time, any chance of an interesting blip for today disappeared as well.
