From National Rail;

Route(s) affected

National Rail routes

Description
There is a nationwide fault with the communication system used between train drivers and signallers. As a result, services across the National Rail network may be subject to disruption this morning.

Trains across the network are having to start their journeys later because of this fault and some may also be subject to cancellations or alterations. Please check before you travel, allow extra time for your journey and monitor live departure boards.

I suspect a russian cyber attack. Such an attack on national infrastructure has been predicted for some time.
Possibly aided and abetted by north korea or iran.

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.

I am curious about the GWR (Great Western Railway) explanation for the cancellations on the early Weymouth service as being the result of communication problems.

The ecs from Bristol for the Yeovil to Filton Abbey Wood service was cancelled between Bristol and Westbury, problem at the depot. It started late from Westbury running to Castle Cary to form the service to Filton.

The first Westbury to Weymouth and return was cancelled - was this because the unit was taken for the Filton service?

Then the first up from Weymouth was cancelled. Was this because the crew are booked come down on the early ecs and get a taxi to Weymouth?

The cancelled services from Weymouth (0733 and 0930) have been reinstated from Bristol and Westbury respectively.

Was the initial problem the communications one and led to the other cascade?

It happened following a planned Signalling Transfer Point card replacement overnight, so more likely just a hardware glitch.

Only seems to affect trains leaving depots for their first run of the day - once in service, they seem to be running normally - says National Rail in an update

Sounds feasible.......Broadgage's theory was more fun though!  Smiley

Apparently if stopped drivers logging on.  Once they had logged on using a slower, secondary, process they were fine.

From Network Rail via X

An overnight fault with our railway radio system in England and Wales has been traced to one of our major hubs near Stoke, which has now been fixed.

From Philip Haigh on X
Quote
Today’s railway problems seem to have followed overnight work to its GSMR radio network. It’s led to drivers having to enter ‘wildcard’ codes into their train systems to connect radios rather than the system doing it automatically. Takes longer than normal, hence some delays.

The fault appeared to affect some areas and not others. SWT (South West Trains) were and GWR main line not. Hence Yeovil Pen Mill in Wessex was in the area affected and Castle Cary wasn't. I think!
