Black 5 pair 44871 & 45407 on GBIII railtour just South of Barrhill, Ayrshire

On Saturday 10th April 2010, a pair of "Black 5" class steam locomotives took the Great Britain III railtour from Glasgow to Stranraer, via Ayr. One of the most severe climbs (1/67) is just South of Barrhill. The locomotives are running smokebox first, with 44871 leading 45407 (Paddy's Engine) Southbound having stopped at Barrhill. This video shows the Black 5 pair climbing out of Barrhill, rounding the curve past the signal and accelerating up the 1/67 gradient away from the camera.
