The forests and mountains of Sierra Leone are a long way from the moors and mills of West Yorkshire, but some train enthusiasts from Leeds have found one striking similarity.
Leeds Industrial Museum is celebrating the city's role in 1915 of building Nellie the engine, Sierra Leone's oldest surviving steam locomotive.
Nellie and other engines were hidden in a shed by railway staff when the 350-mile narrow gauge line closed 40 years ago.

There is also a short video with this BBC report.
