Whitrope Siding was a trailing short siding or spur off the "up" (southbound) line, an associated trailing cross-over between up and down lines, a pair of railway cottages and a signal box on the Waverley Line or Waverley Route. It was used as a goods loading bay. The site is now the home of the Whitrope Heritage Centre, as well as the current terminus of the heritage Border Union Railway.
The siding is located just south of the highest point on the line, the famous Whitrope Summit, 1006 ft above sea level. It is approximately 300 metres south from Whitrope Tunnel, and 4 km north from Hermitage, Scottish Borders.
