Silica sand has been mined in Weferlingen since 1925. Processing results in around 20 different products from the silica, which were previously predominantly transported away on the rails. After the ‘Turn’ in 1989, rail transport became less important and was ultimately stopped completely. Only after a long planning period could the connection be reactivated in 2014, after LWS Lappwaldbahn Service GmbH radically upgraded and reconstructed around 900 m of track on the silica plant premises.

The siding is connect to the Weferlingen train station by 20 points. Between the siding border and the plant premises are three track sidings with working lengths of two times 440 m and one 520 m. There are two platforms for loading in the plant area.
