A 24-hour walkout from London Underground staff is set to go ahead after negotations between rail unions and Transport for London failed.
The strike action is still set to go ahead on Sunday as Rail Maritime and Transport union (RMT) announce talks between the two parties on Wednesday (January 4) did not resolve the "crisis".
Mick Cash, RMT general secretary, said: "RMT is bitterly disappointed that London Underground Limited (LUL) brought nothing new to the negotiating table today despite assurances that fresh proposals to tackle the growing safety and staffing crisis would be forthcoming."
He added: "As a result of LUL's failure to address the issues at the heart of the dispute the talks are adjourned and all action remains on.
"The ball remains in LUL's court and while RMT remains available for talks it is down to the company to come back into the process with serious proposals."
The dispute came to a head in November with a series of strikes after underground staff argued 900 frontline staff cuts and the closure of ticket offices is leaving passengers in a "safety crisis".
Around 4,000 London Underground employees said they were concerned about safety after nearly 900 frontline workers were axed and ticket offices closed.
The union pointed out that the cuts "have left safety on a knife edge with the incidents at Canning Town and North Greenwich throwing the spotlight on dangers which are being worsened by the cuts process."
Steve Griffiths, Chief Operating Officer for London Underground, told getwestlondon : "We have always committed to reviewing our new staffing model with the trade unions during its first year.
"Following talks we are recruiting additional staff for stations and believe this will help us to provide a better service for our customers."
"We will continue working with the unions as well as implementing the independent recommendations made by the London TravelWatch review to ensure our customers feel safe, fully supported and able to access the right assistance at all times.
"We would encourage the unions to work with us on this process rather than threatening strike action."
Rail staff members have been told not to book on any shifts between 6pm on Sunday January 8 and 5.59pm on Monday January 9.
Therefore, the strike will last a day from 6pm on Sunday.
