Like most rail companies across the ITV News Meridian region, Cross Country trains are also affected by the severe weather conditions.
Here are the details of some of the roadworks planned in the South for the coming week.
Plans have been announced to re-open a rail link passing through parts of the Thames Valley and Chiltern Hills.
The High Court ruled that the consultation process for compensating those affected by the HS2 high-speed rail scheme "was so unfair as to be unlawful".
The decision was a victory for the High Speed 2 Action Alliance (HS2AA), which consists of more than 70 affiliated action groups and residents' associations.
The HS2AA case was one of five separate cases brought to block the rail scheme in its current form - it was the only case to succeed.
Mr Justice Ouseley, sitting at London's High Court, is now hearing submissions from lawyers on the appropriate remedy.
Government consultations on compensating those affected by the proposed HS2 high-speed rail scheme were today ruled "unlawful" by the High Court, lawyers Leigh Day said.
The High Court is to rule today on legal challenges to the Government's HS2 high-speed rail scheme.
This report from January by Political Correspondent Carl Dinnen explains the route's location and why it is so controversial:
All lines have now reopened and trains can run on their normal routes after disruption on First Great Western due to a signalling problem between Didcot Parkway and Swindon.
There are still delays of around 30 minutes to services and buses remain in operation. First Great Western expect normal service to resume from around 1pm.
First Great Western have just told us that buses are in place for travel between Swindon to Didcot, Swindon to Gloucester and Bath to Swindon, should passengers want to use them. There are reduced services running between Cardiff and Bristol to Paddington, with trains diverted via Newbury.
ITV News journalist Guy Phillips has just sent us the latest on his attempt to go to Wales. We "We are now boarding a train back to Reading. Great Western hope to get passengers from Reading to Wales via Bath - the long route."
Passengers trying to get to Cardiff are now heading from Didcot back to Reading, following a power failure in Swindon.
Passengers trying to get to Cardiff are now heading from Didcot back to Reading. Those going to Swindon and Bristol are awaiting a fleet of buses to help them reach their destination. Trains from Reading to Wales will go a long route.
ITV News journalist Guy Phillips is stuck at Didcot Parkway in Oxfordshire. His train has been terminated at Didcot. First Great Western Trains have promised buses to Swindon but Guy has been told many as buses are on the school run. Some passengers are heading back to Reading.
Owing to signalling problems between Didcot Parkway and Bristol Parkway all lines are blocked
The power failure in the Swindon area has brought rush-hour trains between London, the Thames Valley, Wales & the Westcountry to a standstill. ITV News journalist, Guy Phillips, is one of thousands of passengers affected. He's just sent us this update.
The 7.11 from Reading to Swansea has been at a standstill at Didcot Parkway for 40 minutes due to amajor power failure. The guard on the train tells us "There is major signalling problems due an electrical fault. The only information we have is to stay here until it has been resolved."
