Wearing a two-tone blue coat and matching hat, the Queen waved to crowds at Waverley Station in Edinburgh as she boarded a train on 9 September for the opening ceremony of the Scottish Borders railway, the longest new rail route to be built in the UK for more than 100 years. Britain's longest reigning monarch was accompanied by husband Prince Philip as she boarded the royal carriage, drawn by the steam locomotive Union of South Africa.

At about 5.30pm on Wednesday 9 September 2015, Queen Elizabeth II surpasses the 63 years, 7 months, 2 days, 16 hours and 23 minutes that her great-great-grandmother Queen Victoria spent on the throne.
