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

Construction[edit]

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

Design[edit]

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