The 360 Class was a small series (12 examples) of 0-6-0 freight locomotives designed for the Great Western Railway by Joseph Armstrong and built at Swindon Works in 1866. They were numbered 360-369, 1015 and 1001, and as built had slightly smaller boilers than the similar and much more numerous 388 Class which went into production later the same year. Their coupled wheelbase was also two inches shorter than that of the 388s. To start with they worked between Birmingham and Chester, though later they were seen in south Wales, at Didcot and in the Birmingham-Stourbridge area. They were withdrawn between 1918 and 1933, the last (No.363) having accumulated in its 70 years an impressive 1,384,645 miles.
