Tube strike talks resume over 72 hour walkout
Talks restarted on Friday between union and Tube bosses in a bid to halt a three day strike on the Underground next week.
The walkout is due to begin on Monday at 9pm, hitting commuters on their return to work after the Bank Holiday.
The RMT, Aslef, TSSA and Unite are in discussion with London Underground at the ACAS offices.
However, it is understood neither side is happy to give ground to prevent a repetition of this week's strike chaos.
Unions want a suspension of plans to close ticket offices and are seeking a full consultation into the job cuts.
But LU's chief operating officer Phil Hufton told ITV: ""We can't keep hanging around, we've got a job to do. We've got to modernise the tube and we've got to become more efficient."
Transport for London is yet to reveal what lines will be affected if next week's strike goes ahead.
This week saw services on the Jubilee line greatly reduced in frequency and not stopping at Southwark, Bermondsey and Canada Water, impacting many commuting to Canary Wharf and the rest of east London.
Meanwhile, works are taking place on the DLR this Bank Holiday weekend.
On Saturday and Sunday the DLR wll not run between Stratford and Poplar. And on Monday it will be suspended between Stratford and Bow Church.
