An RMT spokesman warned although the strikes planned for next week have been suspended other industrial action – including a work to rule by engineering staff which has led to the cancellation of some services – remains in place.
He said the union “remains in dispute” with LU and if the talks fail then further strikes will be ordered.
Night Tube, when it does begin, will see services run throughout Friday and Saturday nights on the Jubilee and Victoria lines and most of the Central, Northern and Piccadilly lines.
