London Overground (LO) services north of Euston and London Underground's (LU's) Bakerloo line services north of Paddington will be subject to essential engineering works, by Network Rail and Transport for London (TfL), between 22 April and 8 May.

Once these works are completed they will help to provide a more reliable service for passengers

The majority of works to upgrade the tracks and signalling will take place over the Easter and May Bank Holidays when passenger numbers are generally lower.

However, planned LO closures will also affect services on seven weekdays, when an increased replacement bus service will be provided.

Howard Smith, Chief Operating Officer, LO said: 'We have worked closely with our colleagues at London Underground to ensure that the works on both the Bakerloo line and London Overground network impact on as few journeys as possible and to ensure that a train service remains for the majority of works.

'When this is not possible a replacement bus service will be provided.

'Once these works are completed they will help to provide a more reliable service for passengers.'

For the Royal Wedding on 29 April, there will be an increased rail replacement bus service between Watford Junction and Harrow & Wealdstone.

For those wanting to travel into central London the Bakerloo line will be running a full service on this day.

The closures are as follows:

Friday 22 April to Monday 25 April

Bakerloo line: Paddington - Harrow & Wealdstone
LO:  Queen's Park - Watford Junction

Tuesday 26 April to Friday 29 April

LO: Willesden Junction - Watford Junction
