Welcome to another SideTracked cache and also the first for me in Lincolnshire.
The railway station originally served Rauceby Mental Hospital (the former Kesteven Lunatic Asylum, which lies immediately to the south of the railway station and was closed in 1998) and the village of South Rauceby in Lincolnshire, England. The line was built by the Boston, Sleaford and Midland Counties Railway. It now principally serves commuters living in the new housing estates that comprise the Greylees suburb of Sleaford.
The former leader of the Liberal Democrat Party, Nick Clegg, proposed to his wife on a platform at the station. (Notta Lotta people know that).
The cache is a recycled one, maybe you have seen it before since it was left in situ by a previous cache, I like to recycle. There is not much room as the log is small, however I think the container is fun and should be reused.
Happy Hunting.
