The '''Highland Railway Strath Class''' were [[4-4-0]] [[steam locomotives]] introduced in 1892, to the design of [[David Jones (railway)|David Jones]].

==Construction==
Twelve were built by [[Neilson and Company]] and delivered between May and July 1892.

==Design==
They were identical to the [[Highland Railway E Class|class E]] ''Clyde Bogies'' apart from having boilers of a larger diameter which allowed an increased heating surface.
