A series of strikes are to go ahead on some of the country's busiest rail routes in the long-running dispute over guards, a union has confirmed.
Members of the Rail, Maritime and Transport (RMT) union on South Western Railway will walk out on eight dates from July 26 to the beginning of September.
The move follows a deal between the union and Greater Anglia to end a similar dispute, which the RMT said guarantees a guard on trains.
RMT general secretary Mick Cash said: "RMT is making a very simple request of South Western Railway - that they take note of what is going on elsewhere in the rail industry and come forward with serious proposals that give a cast-iron guarantee of guards on their services and a halt to the rolling out of driver-only operation.
Meanwhile, fresh strikes are to be held by London Underground maintenance workers in disputes over pay.
Members of the RMT union based at the Ruislip depot will stage two 12-hour strikes over the weekend of August 3 and 4.
General secretary Cash said: "Despite previous industrial action there has been no serious move by London Underground to resolve these disputes, which is why we have been left with no choice but to press on with a campaign of strike action in the pursuit of justice for our members."
