The Rail, Maritime and Transport union (RMT) has announced more action over pay, jobs, pensions and conditions.

This means there will be disruption to both the rail and Tube network across the month.

Meanwhile, the ASLEF union also announced overtime bans and strikes in a dispute over pay.

ASLEF represents drivers, whereas RMT represents members from lots of different sectors within the rail industry - including station staff and guards.

When ASLEF members go on strike, it usually means there are no drivers. When RMT members go on strike, there is widespread disruption to the network with lots of people in different roles going on strike.

Here is everything you need to know:
