What is highland railway castle class?

The Highland Railway Castle Class is a type of steam locomotive that was built for the Highland Railway, a railway company in Scotland, in the late 19th century. They were designed by Dugald Drummond and built between 1894 and 1898.

There were a total of 34 Castle Class locomotives built, and they were used on the Highland Railway's mainline, which ran from Perth to Inverness and on to the Far North of Scotland. They were designed to be powerful and reliable, capable of hauling heavy loads over steep gradients and difficult terrain in Scotland.

The Castle Class locomotives had a 4-6-0 wheel arrangement, meaning that they had four leading wheels, six driving wheels, and no trailing wheels. They had a large boiler, which powered their steam engines, and were noted for their distinctive curved smokeboxes.

Despite their strength and reliability, the Castle Class locomotives were gradually retired from service in the mid-20th century as newer, more modern locomotives were introduced. Today, a few examples of these locomotives can be seen in museums and heritage railways across the UK.
