Torr Works Quarry is the correct name of the quarry known by collectors (and seen on maps) as 'Merehead Quarry'. Merehead is actually the name of the railway head at the quarry.
A limestone quarry run for many years by Foster Yeoman, but now owned and operated by Aggregate Industries. Annual output 6 million tonnes (taken from their website).
NOTE: "... most of the new specimens sold during 2007/2008 as Merehead Quarry, are actually from Durnford Quarry." (http://www.mindat.org/mesg-11-135845.html)
