The Highland Railway Loch class locomotives were small 4-4-0s normally used north of Inverness.
They were introduced in 1896, the design of David Jones, and had the typical Jones appearance with outside cylinders, domed cab roof, louvered chimney,but as with the Jones Goods class 4-6-0 the Allan style front framing was dispensed with.Allan valve gear was still used.

These were needed primarily for the increased traffic on the Kyle line where they were the heaviest locomotives permitted. It should be remembered that this period was when the initial traffic of the United States effort in World War I was flowing, and much was brought to the west coast of Scotland in an effort to reduce the effect of the U-Boat menace. The trains ran from Kyle to Invergordon so it was a wholly HR traffic.
Withdrawal occurred from 1930 onwards, with only two surviving into British Railways ownership. Neither received their allocated BR number before being withdrawn in 1948 ('Loch Insh') and 1950 ('Loch Tay').
They were classified '2P' by the LMS.
