Rail strikes: Wales hit by biggest rail strike in 30 years
Rail passengers in Wales are having to cope with the biggest strike in 30 years.
Fewer than 10% of normal services will run, Network Rail confirmed, on the first of three days of industrial action across the UK.
Last-minute talks between unions and rail bosses failed to broker peace in a row over pay and proposed job losses.
Commuters have been advised to avoid travelling by train as the few services that are running are likely to be full.
Thousands of staff at Network Rail and 13 rail operators walked out from midnight after last-ditch talks to avoid the strikes failed.
The RMT rail union accused the government of preventing employers from freely negotiating on pay.
just one in five trains are expected to run on Tuesday, Thursday and Saturday when workers are on strike.
The remaining trains will run predominantly on main lines and only for about 11 hours
Network Rail urging passengers to travel by rail only if necessary.
