Three strike days originally planned for Merseyrail workers have been suspended.
The RMT announced on Thursday that plans to walk out on Saturday, as well as two further days in September - will no longer go ahead.
The strikes were originally announced as part of six days of action, but the RMT has said the latter three days at the end of September and start of October, will still go ahead.
The action would have hit commuters as well as shoppers and football fans both in Liverpool and across Merseyside if it had gone ahead this weekend.
The RMT says "significant progress" has been made in addressing its members' concerns, and that further detailed discussion will now take place.
The news means there will no longer be strikes on August 24, September 3 and 5, while the strikes on September 30, October 2 and 4 will still go ahead.
A statement from RMT said: "Following a positive meeting with Steve Rotheram Metro Mayor, MerseyTravel and the RMT fresh proposals have been made which represent significant progress in regards to addressing RMT’s concerns.
"In order to allow for further detailed discussion the RMT has agreed to suspend industrial action called for 24th August, 3rd and 5th September 2019."
After the news was announced, Mayor Rotheram said: “As a result of constructive talks yesterday between myself, Cllr Liam Robinson, RMT General Secretary Mick Cash and local RMT reps, I am pleased that a potential way forward has been found.
“I welcome the union’s decision to call off the strike action planned for this Saturday, Tuesday 3 September and Thursday 5 September. This is good news for passengers and underlines that significant progress is being made towards reaching a final resolution to this long-running dispute.”
