Bus passengers face further disruption to services this week as drivers prepare to take strike action again.

Transport for London (TfL) is warning customers of disruption to bus routes across the capital, including services operated by London Sovereign.

If the 24 hour strike action goes ahead as planned on Wednesday, some journeys in Hertfordshire will be affected, and possibly more so than before with schools fully reopened.

This includes the 142 and 258 routes which operate via Watford Junction.

The full list of routes across north west London and Hertfordshire affected by strike action include: 79, 142, 183, 251, 258, 288, 303, 326, 395, 398, 642, N5, H9, H10, H11, H12, H14, H17, H18 and H19, between 12am on Wednesday (March 10) until 11.59pm the same day.

TfL says it will ensure as many bus services run as possible but customers are advised to check before they travel, leave extra time for their journey, and where possible, consider alternative transport.

London Underground services will be operating as normal.

TfL has also urged bus operator RATP Dev London and Unite the union to "resolve the issue as soon as possible".

Strike action has already taken place over the few weeks because of a dispute over pay and conditions.

More than 2,000 members of the Unite union who are employed by French-owned RATP have taken action.

RATP operates three subsidiaries across the London bus network – London Sovereign, London United and Quality Line.

Unite officer Michelle Braveboy has previously said the strikes will cause "serious disruption" to services, adding that terms and conditions are being "attacked", with some drivers facing a pay cut of £2,500 a year.

She also said: "Our members have no option other than to fight back against these attacks, while recognising the disruption caused.

"They are reluctant to take strike action at a time of national emergency, but feel they have been pushed against the wall."
