Rail workers have voted in favour of strike action which could lead to major disruption for commuters across the UK.
Southern Rail engineers say they will hold a five-day strike, starting on 12 July, joining Northern Rail.
The Rail, Maritime and Transport (RMT) union said the strikes come after a "comprehensive breakdown" of relations between workers and employers.
The London Underground will also be affected after RMT members voted to join the Aslef union in a 24-hour strike on 8 July over the 'Night Tube'.
RMT members working for First Great Western are also planning to walk out at 18:30 on 8 July. Southern Rail workers will walk out at 17:00 on 12 July and ban overtime on the proceeding weekend.
RMT said the strikes are likely to affect services. It follows disputes with Northern Rai over plans to replace some permanent positions with zero-hour contract workers.
