'Butterflies in my stomach'published at 13:56 British Summer Time 7 September 2015
Former MSP Jeremy Purvis, now Lord Purvis of Tweed, was one of the driving forces behind plans for the Borders Railway.
"I can't tell you how exciting it is," he said. "I have got butterflies right in the pit of my stomach."
He said that when the bill was going through Parliament he "sometimes did wonder" whether it would ever come to fruition.
"Today is so exciting to be joining so many excited people as part of the first service."
