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.

From Journeycheck Delays to services between Taunton and Exeter St Davids
Due to a fault with the signalling system at Exeter St Davids some lines are closed. Disruption is expected until 09:15 08/02.
Train services between Taunton and Exeter St Davids may be delayed.
Additional Information
The track circuit which allows the signaller to safely see which trains are occupying different sections of track has failed at the western end of Exeter St David's station. This has locked a set of points into one position, meaning some trains can't switch between different tracks.

As a result, the number of available platforms at Exeter St David's that trains can use will be reduced from 6 to 2.

Services between Exeter Central & Barnstaple will start/terminate at Exeter St David's.

Services between Exmouth & Paignton will start/terminate and restart at Exeter St David's.

That's quite a truncation - only the first 3 minutes of 71!

Still very much worth flagging up - it may be only 4% of the journey time to many, but for those wishing to start their journey at Exeter Central and turning up at their usual time, it's 100% of the journey ruined.

On investigating the fault, Network Rail have discovered that approximately 100 metres of signalling cable has been stolen.  Angry
