Narrowboat out of control and crashes on the Grand Union Canal.

A narrowboat goes out of control and crashes on the Grand Union Canal. The poor boater got caught after passing us and lost control of his boat. We leave Milton Keynes and visit the Wolverton Railway Works where the Royal Train lives. We cross the Wolverton Iron Aqueduct and take a look at the disused locks down to the Great Ouse River before heading to Stoke Bruerne.
