An off-peak day return from Truro to Exeter is only ^16.40
correct, although for a return as i required from Truro to London Gatwick, at the times of my travel (1 week apart stupid times of the day) it saved me almost ^150 going from Exeter as opposed to Truro, [/quote]
I wonder if there'd be much scope for an hourly Plymouth-Penzance calling at Liskeard, Bodmin Pway, St Austell, Truro, Redruth, Camborne, St Erth and Penzance every hour (and Par and Hayle every other hour), with a Plymouth-Newquay service calling at all stations every hour (or at least every 2 hours). But as it would involve sufficient trains and track capacity (and wouldn't be great for Newquay line passengers), it probably isn't likely.
would Par needs a more frequent service than 2hourly for connections to the Newquay branch,
