Commuters travelling through Watford and Milton Keynes Central should stock up on patience before travelling today after an earlier signalling fault is still affecting trains.

All lines have now reopened after the signalling system fault at Leighton Buzzard, but trains from London Euston running between the stations could still be cancelled or delayed by up to 20 minutes.

Here are the routes that are set to be affected until the end of the day.

• Avanti between London Euston and Birmingham New Street / Chester / Holyhead / Liverpool Lime Street / Manchester Piccadilly / Lancaster / Blackpool North / Glasgow Central / Edinburgh
• London Northwestern Railway between London Euston and Milton Keynes Central / Birmingham New Street / Crewe

The A315 Staines Road near Heathrow has been closed in both directions since the morning after an earlier crash.

An investigation is ongoing, and the road remains closed both ways between A244 Hounslow Road and Barrack Road, traffic service Inrix said.

Buses 116, 117 and 235 are diverted.

Traffic is currently coping well in the area.

After a major signalling problem affecting the London Overground and Southern trains for hours, lines have now reopened.

However, the coast is not clear yet for passengers – trains could still be cancelled or delayed by up to half an hour as service recovers.

The fault wreaked havoc on trains and the Overground between Shepherds Bush, Wembley Central and Willesden Junction throughout lunchtime.

Southern told passengers to keep checking their journey before travelling although all lines have reopened.

As well as Heathrow having a very busy August, two other airports had a record-breaking summer, according to figures released today.

Brits have clearly been desperate for a holiday, as Manchester Airports Group, which owns and operates Manchester, Stansted and East Midlands Airports, said passenger numbers reached nearly seven million in August. This is up 6.6% from the same month in 2023.

Individually, Manchester Airport and Stansted Airport near London both had their busiest ever months in August, with 3.4 million and 3.1 million passengers respectively.

I wonder if they will sell the same numbers in September now that Pret’s drink subscription has controversially been withdrawn?

Signalling problems are causing a headache for passengers travelling between Watford Junction and Milton Keynes Central this afternoon.

People have been warned to expect delays of up to 45 minutes due to the problem at Leighton Buzzard, which means trains are having to go slower than usual.

Disruption is expected to continue until 1.45pm. The routes affected are:

Avanti between London Euston and Birmingham New Street / Chester / Holyhead / Liverpool Lime Street / Manchester Piccadilly / Lancaster / Blackpool North / Glasgow Central / Edinburgh

London Northwestern Railway between London Euston and Milton Keynes Central / Birmingham New Street / Crewe

No trains at all are running on the London Overground between Stratford and Clapham Junction and Southern between Watford Junction and East Croydon, National Rails says.

This is due to a signalling failure between Shepherds Bush and Wembley Central/Willesden Junction which has blocked all lines.

While Network Rail said this issue should have been fixed by now, the association now says there will be no trains until ‘approximately’ 2pm.

Inrix, a transport analytic firm, reported to YorkshireLive: ‘Traffic easing, accident cleared on A1 Southbound from A162/A1(M, Darrington) to B6474/Went Edge Road (Wentbridge South/Kirk Smeaton Turn Off, Wentbridge).

‘All lanes have been re-opened.’

A vehicle recovery effort along the M25 is likely causing some headaches for drivers.

One of four lanes is closed on the M25 clockwise between J8 (Reigate/Redhill) and J9 (Leatherhead/Epsom), according to Motorway Cameras.

Normal traffic conditions aren’t expected until 12pm.

M25 anti-clockwise within J16 (M40 J1A/Uxbridge) is also seeing a fair amount of traffic but should be easing up very shortly.

National Highways’ Yorkshire wing has issued a new update on the A1, also called the Great North Road, which has been suffering delays for most of this morning.

The agency said in a post on X: ‘The vehicles involved in the earlier collision on the A1 south between J40 (Darrington) and J39 (Doncaster) have now been recovered from the scene.

‘All lanes have been reopened with residual delays of up to two hours on the approach.’

Commuters hoping to use two major London train lines today are being asked to use different routes.

London Overground between Stratford and Clapham Junction and Southern between Watford Junction and East Croydon are seeing disruptions, National Rail says.

A service update says: ‘A fault with the signalling system between Shepherds Bush and Willesden Junction means all lines are blocked.

‘As a result, trains may be cancelled, delayed or revised. This is expected until 12:30pm.’

Things aren’t looking too great on the A1, a major north-south motorway which connects London with Edinburgh, according to the National Highways.

Multiple junctions are experiencing severe congestion, with delays of as little as 10 minutes for some and one and a half hours for others.

One driver stuck on the A1 southbound said on X that delays are ‘coming up for two hours now’.

•  The A1M southbound between junctions J41 and J40 to A1 southbound between the M62 and the junction with the A639 will see delays of an hour and a half until 10.45am after a collision.
• The A1 northbound between the junctions with the A603 and the A421 is seeing 10-minute delays until 10.45am.
• The A1 northbound between the A167 Washington Birtley and the junction with the A692 is seeing 15-minute-long delays until 10.45 am.
• The A1 northbound between the A638 and the junction with the M62 is seeing 10-minute delays due to congestion.
• The A1 southbound between the junctions with the M62 and the A639 is seeing delays an an hour due to a road collision until 12.15pm.

TfL has just said that the Overground is partly suspended along a large chunk of the line in central, south and northwest London.

‘No service between Willesden Junction and Clapham Junction due to a signal fault in the Shepherd’s Bush area,’ the agency says.

Congestion is being reported by Motorway Cameras, a website that, well, keeps an eye on motorway cameras.

Logjams were spotted on the J22 clockwise exit and clockwise between J22 (St. Albans) and J23 (A1(M)J1/Barnet). Things are expected to let up from about 10am.

A number of London Euston lines operated by London Northwestern are seeing delays.

Both Crewe via The Trent Valley and the West Midlands via Northampton are experiencing delays due to a faulty train at Milton Keynes Central.

The delays should last until 10.30am, the operator says.

The delays to Southern and Thameslink services on some routes are now expected to last until 10am, rather than 9am, Network Rail now says.

‘As a result, trains running between London Bridge and Sydenham, and between Balham and London Victoria, may be delayed by up to 15 minutes,’ the government-backed owner of Britain’s train tracks said.

Network Rail is reporting that there will be ‘some delays’ to Southern and Thameslink services until about 9am.

The alert says ‘multiple incidents’ on the two lines including a points failure at New Cross Gate and a safety inspection on the tracks at Balham are behind the disruption,

Routes impacted include: ‘Southern between London Bridge and London Victoria / Epson / Caterham / Uckfield, between East Croydon and Watford Junction, and also between Horsham / Sutton / West Croydon / Epsom Downs / Dorking / Selhurst and London Victoria.

‘Thameslink between Bedford / Cambridge and Brighton, between Bedford and East Grinstead / Three Bridges / Haywards Heath, between Flitwick / London Bridge and Three Bridges, and also between Peterborough and Horsham.’

In a rare bit of a good travel news, it seems things are settling down on TfL network.

There’s good service on all lines other than the Victoria line, which is experiencing minor delays between Seven Sisters and Walthamstow Central due to a fault train over in Victoria.
