The JGR Class 9150 (originally the JGR Class F1) was a 2-8-0 Consolidation-type steam locomotive built for the JGR from 1900 to 1908.

History

The 9150s, originally known as the Class F1s, were used mainly as freight locomotives and were the first locomotives to be built at the JGR's own shops. Ten locomotives were produced by the JGR's Kobe Works from 1900 to 1908. The design was overseen by Richard Francis Trevithick (grandson of Richard Trevithick) who was working in the JGR's Kobe Works at the time as a locomotive inspector.

The locomotives were meant to be used on steep gradients such as the Itaya Pass. The locomotives were later renamed to Class 9150 in 1909 with the establishment of a formal rule regarding locomotive naming. During their service lives, the locomotives served in tandem with the Class B6s and Class F2s. The locomotives were retired in 1925, with none being sold to private railways.

No locomotives survived into preservation.

Trivia

• The Class 9150s were the only British-style 2-8-0 Consolidations owned and operated by the JGR; almost all Consolidations prior to the 9150s (and after them, as a matter of fact) were American-styled.
