Disability campaigners are to stage a demonstration in support of the long-running protests against changes to the role of guards on trains.
The Rail, Maritime and Transport union (RMT) has been embroiled in industrial disputes with five train operators, leading to strikes and other forms of industrial action.
Disabled passengers will protest on April 18 at Waterloo station in London against South Western Railway, one of the companies involved in the bitter row.
The RMT is staging an event in Westminster on April 25 to mark the second anniversary of the guards' row, which started on Southern Railway.
Merseyrail, Arriva Rail North and Greater Anglia are also involved in the dispute.
