CORNWALL’S REMAINING OPERATIONAL BOXES
THERE are four signalboxes still controlling parts of the Cornish Main Line at Penzance, St Erth, Roskear and Liskeard, of which those at St Erth and Liskeard retain semaphore signals. There are also two working ’boxes on the Newquay branch at St Blazey and Goonbarrow, both of which have semaphores.
