London train strikes to disrupt travel on Tuesday and Thursday

LONDON, June 1 (Reuters) - Strikes ​are ⁠set to disrupt travel in ​London on Tuesday and Thursday, with some ​London Underground ‌train drivers staging two 24-hour walkouts over proposed ⁠changes to their working ⁠hours.

The RMT union ​confirmed on Monday that the walkouts would go ahead as employer Transport for London had "failed ​to ‌provide assurances on our members' deeply held concerns" around fatigue, reduced flexibility and shift lengths. TfL did not immediately respond to ​a Reuters request for comment.

The union ‌called off planned strikes last month to allow for further talks ‌with TfL.

* TfL says drivers to walk out from 2301 GMT on June 1 ​to 2259 GMT on June 2

* Identical strike planned ‌from June 3 to 4

* Significant disruption expected across London

* The strikes do not ⁠affect ⁠the entire Underground network, but ‌some lines are expected to have no service, according to ​the ​TfL website

* Train services ‌will start late and finish early, with levels varying across the network (Reporting by Muvija M; Editing by Kevin Liffey)
