As previously reported earlier in the year unions representing staff from London Underground have organised industrial action on three dates.
Tuesday 26th January
Monday 15th February
Wednesday 17th February
The timings of the strikes differ due to different unions being involved, three unions start their action at 18:30hrs, with one union starting theirs at 21:15hrs.
Each strike will last for approximately 24hrs with end timings on certain lines and stations being different due to the number of unions being involved.
The unions involved have also stated that timings may change prior to the action commencing.
