FOLLOWING a two-week engineering blockade of the Cornish Main Line at the end of February and start of March, signalling control at three signalboxes dating back to the 1890s will pass to a workstation at Exeter Panel.
Truro, Par and Lostwithiel ’boxes will all close, but there are at least no plans to demolish any of the structures, while those at Lostwithiel and Par are Grade II-listed and so few alterations may take place.
The changes mean that the Cornish Main Line is now signalled by Plymouth Panel (Plymouth to Liskeard); Liskeard; Exeter Panel (Liskeard to Roskear); Roskear ; St Erth; and Penzance. Of these, the ’boxes at Liskeard and St Erth still have traditional lower quadrant semaphore signals, as do two further ’boxes on the Newquay branch at St Blazey and Goonbarrow.
