PASSENGER trains started running on the Borders Railway for the first time in 46 years on September 6 following the completion of a £294m project to reopen the 48km line from Edinburgh south to Tweedbank.
It is understood that Wednesday will be a normal working day for the monarch with no special celebration.
She will be joined by the Duke of Edinburgh to open the £294m Scottish Borders Railway and make a steam train journey with Scotland's First Minister Nicola Sturgeon.
