Heck of a lot of Steel sleepers in and along the line from Carbis Bay to St Ives.

I don't Understand the Quote from Rail Advent that this is the biggest investment in Track renewals in Cornwall since the 1950s, this relaying will extend the CWR^▸ (Continuously Welded Rail) laid from St Erth towards St Ives  that was installed about 4 years ago.
Would think the whole branch will be CWR after work is completed, so if 1 1/2 miles is being done then 3 miles has ALREADY been relaid with CWR.

Anyone know the extent of the damage to the unit (a 150/2 I understand) and whether it will be OOU^▸ (out of use) for any length of time?

Signals are normally provided to allow a specified minimum headway time between trains.  There are lots of other considerations, such as sighting distance and SPAD^▸ (Signal Passed At Danger) risk mitigation.  Having a signal at the end of a station platform is potentially a SPAD risk as station duties can be a distraction, causing the driver to forget the previous warning signal.  In the case of Bodmin Parkway the starting signals have been placed a trains length ahead of the platforms and can be clearly seen by a train stopped at the station, but even then the Down signal has been provided with a banner repeater signal (probably to comply with signal minimum reading time).  However, this is not always possible due to line curvature.

So in summary, its a mix and match of issues that need to be considered at a particular site.

The new signals between Truro and St.Erth are due to be commissioned next month I believe.

Has CP6^▸ (Control Period 6 - The five year period between 2019 and 2024) funding/expenditure yet been confirmed? I think not perhaps...

Welcome to the forum, Cornish bobby.

We're tending to thing that the project hasn't been cancelled.  However, I'm not sure that the chair of Network Rail would necessarily be one go the first to be aware; he's got a lot on his plate looking after infrastructure and signalling without worrying about exactly what's going to be running on his tracks.
