The industrial action is expected to impact 14 train companies, resulting in additional travel disruptions across a significant portion of the rail network.
"The government is once again not allowing the Rail Delivery Group to make an improved offer that we can consider," General Secretary of Rail, Maritime and Transport (RMT) Mick Lynch said in a statement on Thursday.
"Therefore, we have to pursue our industrial campaign to win a negotiated settlement on jobs, pay and conditions," he added.
He said with a fresh mandate for a six-month strike, RMT members unwaveringly stand behind the campaign and are resolute in their determination to persevere until a satisfactory resolution is achieved.
