How can I stay in the loop?
National Rail urges anyone hoping to travel on strike and overtime ban days to use its Journey Planner to keep an eye on how services will be affected.
What has been said about the strikes?
The union claims drivers have not had a pay rise since 2019.
ASLEF General Secretary Mick Whelan said: “We have given the government every opportunity to come to the table but it is now a year since we had any contact from the Department for Transport. It’s clear they do not want to resolve this dispute.
“Many members have now not had a single penny increase in pay for half a decade, during which time inflation has soared and, with it, the cost of living. We didn’t ask for an increase during the pandemic, when we worked through lockdown, as key workers, risking our lives, to move goods around the country and enable NHS and other workers to get to work.”
He urged the government to “come to the table” to end the dispute.
