...and was puzzled to see that next to my seat a small part of the side of the train was made of a mysterious transparent substance. Being unsure what this could be, I asked one of the Virgin staff who explained that if you heat up sand you can by some alchemical process turn it into something transparent yet hard called 'glass'. He went on to say that if Virgin's bold experiment with this revolutionary substance were deemed a success, that maybe in future trains it may be more extensively applied. Personally I'm not convinced. Being able to see Stoke was a pretty horrifying experience and I'm sure other Virgin passengers will agree that it's better to be shut up in the comforting world of plastic and artificial light that they are used to.
