The reference for locomotives and railcars
French Western Railway No. 500
France | 1884 | only one produced

After the compound locomotives of the Webb type were apparently successful in Great Britain, the Ouest also ordered one locomotive for trials. Like the British locomotives, it had two small outer high-pressure cylinders driving the second driving axle and one large inner low-pressure cylinder driving the first driving axle. These two axles were not coupled to each other. The number 500 was rebuilt in the meantime, but was already retired in 1901.
