There is a landslip at Lydney but with Gloucester Panel closed until Sunday morning, as Graham says, there are no services are booked to run through the area. (Lydney is actually covered by Cardiff Signalling Centre - but there is no access from the east.)
And again?

All trains running between Gloucester and Cardiff have been suspended for the rest of the day after flooding caused a landslip on the line. National Rail say that the incident occurred between at Little Hagloe, near, Lydney, and all lines are currently closed.
"As a result, trains are unable to run between Cardiff Central and Gloucester until at least the end of the day," reads a post on National Rail's website.

A spokesperson for National Rail said that 1,000 tonnes of spoil fell during the landslip, meaning that the firm do not want to re-open the line tonight. Commuters are asked to check their journey before travelling tomorrow (January 15).
Delighted at the comment that commuters should check before travelling what is now today - Sunday. A welcome admission that Sunday is now a part of the working week.
