Four days of scheduled work stoppages against Network Rail were announced by signalers, maintenance workers and supervisors, The Times of London reported Friday.
The workers said they would conduct two 4-hour stoppages at rush hours on the days of the strike -- one from 6 a.m. to10 a.m. and the other from 6 p.m. to 10 p.m.
British Prime Minister Gordon Brown said a rail strike is in "nobody's interest."
Transport Secretary Andrew Adonis called for a return to negotiations, the Times said.
"Both sides should seek to resolve this dispute by negotiation and not confrontation, and I am urging them to do so," Adonis said.
An aide said Adonis would not get involved in the dispute between a private company and the unions.
