Highland Railway O Class

The Highland Railway O Class locomotives were built as 2-4-0T tank engines, but were soon rebuilt as 4-4-0Ts. They were designed by David Jones for Scottish Railway companies and three were built at the company's Lochgorm Works in 1878 and 1879.

Dimensions

They had coupled wheels, outside cylinders and weight of 36 tons.

Rebuilding

They were rebuilt as 4-4-0Ts in 1881–82 due to trouble with the single leading axle.

Transfer to LMS

All three were still in service in 1923, although relegated to shunting duties, and they were transferred to the London, Midland and Scottish Railway at the Grouping.

Withdrawal

The three locomotives were withdrawn and scrapped between 1928 and 1933.
