Two walkouts by workers who maintain the tracks for London Underground (LU) were suspended by the RMT union last week.
Around 1,500 maintenance staff working for LU and Tube Lines are defending basic safety issues over track access.
Their action is suspended for two weeks after bosses proposed a “comprehensive safety review”.
Talks are expected to resume again after it takes place.
Track patrol workers are in dispute over LU bosses training Cleshar agency staff to do their jobs, which bosses say was necessary to fill rosters.
Their action was also suspended for two weeks while bosses agree to suspend the training and look at rostering arrangements with the union.
Talks are to resume after this period.
