Metronet staff will be transferred to London Underground in December
Thousands of workers from the failed Tube maintenance firm Metronet will be brought back by Transport for London by the end of the year, it was announced.
Some 6,000 Metronet staff are expected to be transferred to London Underground by December.
The Rail, Maritime and Transport Union (RMT) welcomed the plan.
The announcement is now expected to end a long-running dispute which has seen Tube workers striking over fears they would lose out over pay and conditions.
Union leaders felt workers would be forced to join other employers and suffer worse pension deals when Metronet contracts were transferred to TfL in May.
"It is another small step on the road for a properly integrated transport system for London after the disastrous experiment with the public private partnership," said the RMT's leader Bob Crow.
"Next up, Tubelines' operations should be brought back in-house."
A TfL spokesman said: "London Underground and Metronet have begun consultation with unions and staff on the TUPE transfer of staff from Metronet to London Underground, which we hope to complete in early December."
TfL said the move would be in the interest of staff and customers, and would "provide greater stability and integration".
Metronet, which was responsible for two thirds of the Tube network, went into administration last July after an estimated £2bn overspend.
TfL is now consulting with union leaders from the Transport Salaried Staffs Association (TSSA) ASLEF, and the RMT over the details of the London Underground transfer.
