Members of Aslef will hold a rolling programme of one-day walkouts between April 5 and 8, along with a six-day ban on overtime.
Aslef general secretary Mick Whelan said: "Last month, when we announced renewed mandates for industrial action, because under the Tories' draconian anti-union laws we have to ballot our members every six months, we called on the train companies, and the government, to come to the table for meaningful talks to negotiate a new pay deal for train drivers who have not had an increase in salary since 2019.
"We asked Mr Harper, or his deputy, the rail minister Huw Merriman, to come and meet us. We asked the Rail Delivery Group and the Train Operating Companies to come and talk to us."
