The Highland Railway F class 4-4-0s were introduced in 1874. The first 10 were built by Dübs and Company in 1874. A further seven were built in Lochgorm works between 1876 and 1888.
They featured 6 feet 3 inch driving wheel and weighed 41 tons. The original batch had boilers pressed to 140 lb per square inch, the later batch had slightly smaller boilers but a higher pressure (150 lb/sq inch). Of typical Allan/Jones appearance, they had outside cylinders of 18" by 24".
The first 10 were numbered 60 to 69 and originally named as follows:
| HR No. | Name | Notes |

All were later renamed at least once. No. 62 was renamed name three times.
