I still find it hard to understand the logic of a mixture of old mechanical signalling with that of a modern network all controlled from one ROC (Rail Operating Centre - a centralised location for railway signalling and train control operations for a specific route or region). It seems a "pig's ear" of a scheme to me and probably fraught with difficulties.

You need a £100 million computer system, lots of LED lights, a GSM radio system with capability for transmission of telemetry data at high speed, a whistle, a flag and some large bangy things to stick on the rails when it's foggy, so the driver of the £50 million train knows that there's a broken down steam engine ahead.

And so that the driver of a steam engine knows that there is a broken down £50  million new train ahead !

A proper intercity train has a minimum of 8 coaches, gangwayed throughout, with first at one end, and a full sized buffet car between first and standard.
It has space for cycles, surfboards,luggage etc.
A 5 car DMU (Diesel Multiple Unit) is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.

This has developed into a thread with two halves hasn’t it? Until sometime in January it was about a future resignalling project due to complete in 2023.  Has work actually started on that?

Then from post 17 onwards it was suddenly all about day to day faults, theft or vandalism.

Are the two subjects actually related at all?  Huh

Guilty as charged.
I didn't spot the REsignalling at the time of my first post.

So Mods, please split this into two if possible, perhaps with a title of Cornwall signalling problems? as the thefts have been in Cornwall.

I note that the list of engineering works due later this year on GWR (Great Western Railway)'s website includes:
- 5th, 6th & 13th November: St. Austell to Penzance
- 19th & 20th November: Lostwithiel to St. Austell
- 05th - 08th December: Truro to Penzance, incl. St. Erth - St. Ives
- 27th - 30th January: Par to Newquay

I presume, without knowing for sure, that the works of November and December will be related to the resignalling in terms of installation of the replacement signals - Sad - but I am not sure when the new setup is due to be commissioned. As for Par to Newquay this could also be for work on the same project to make a few alterations.
