Thanks dtb.
The Winsford mine is still operating, producing rock salt for road gritting.
Back in the 19th century there were numerous salt mines and salt works around Northwich, Middlewich and Winsford, but now just the one mine remains.
Brine is still extracted from the fields around us and is pumped to the former ICI chemical works at Lostock Gralam for use in soda ash manufacture. Trainloads of limestone are still delivered to the works from Derbyshire for use in the same process.
One of the old open pan salt works (Lion Salt Works) at Marston is now preserved as a museum. One of the distinctive salt vans has been refurbished and is on display outside the museum.
Until the mid 1960s a branch line ran from just outside Northwich station to Marston serving both Lion Salt Works and the more modern New Cheshire Salt Works. The latter business closed in 2006.
Part of the track bed of the branch, including a steel bridge over a small brook is still visible in places.
Northwich shed (8E) used to have an allocation of Ivatt 2MT locos to work the salt branches.
