The Highland Railway Strath Class were 4-4-0 steam locomotives introduced in 1892, to the design of David Jones.

Construction

Twelve were built by Neilson and Company and delivered between May and July 1892.

Design

They were identical to the class E Clyde Bogies apart from having boilers of a larger diameter which allowed an increased heating surface.
