Just over 3 weeks to go until our planned closure of #CharingCross & #WaterlooEast 🚧 From Sun 26 July to Sun 16 Aug 2026 (plus some surrounding weekends), we’re delivering once-in-a-generation upgrades. Tell us how this affects your travel questionpro.eu/t/AB3u1DTZB3w… (it will take 2 mins & is confidential) Please plan ahead: @Se_Railway 👉ticket.southeasternrailway.c… TfL for London Underground, buses, cycling & walking tfl.gov.uk/plan-a-journey/ Safer, more reliable journeys ahead

Yesterday, passengers travelling with @SouthernRailUK , @TLRailUK + @GatwickExpress endured an awful evening after we lost the ability to run trains on the busiest part of our network, shown in the picture, for over an hour. Here is what happened... 1/

Our boss John has posted this on our website, which has a more detailed look at the technical aspects of what went went wrong. We know this won't make up for yesterday but we hope it helps your understanding and shows how seriously we take this. Thank you. networkrail.co.uk/running-th…

1/ We are in the final days of a major project to rebuild the complex and busy Lewisham Junction, #London This thread will look at the various stages of work over the past 8 days, and why the project is important for @Se_Railway passengers.

Passengers travelling from Charing Cross will have spotted our new full colour departure boards, installed over Christmas (the data on the screens in the picture is a test!). They are brighter, clearer, colour coded and feature Underground updates too - we hope you like them!

When #Hastings signaller Clive originally planned to come to work as The Grinch today, little did he know how right he would be about Christmas! A boy on a train spotted him this morning but his parents didn't, so somewhere in Sussex there's a family wondering what happened! /1

A beautiful sunrise has greeted us at the opening of the full London Bridge!

This was Norwood Junction earlier today where a bus collided with a railway bridge, causing delays to @SouthernRailUK and @TLRailUK passengers. Trains are now on the move again with some delays but if you’re a driver of any large vehicle, you must know the height of it.

1/ A new signalling system is controlling the movement of @SouthernRailUK @TLRailUK and #LondonOverground trains in south #London. After four years of work, in the ‘wee’ hours of Saturday morning, the old 1980s system was switched off and the new system switched on. In the image below you can see the new workstation at the Three Bridges Rail Operating Centre where trains in the #TulseHill, #Peckham, and #CrystalPalace areas are now controlled.

“Why did my @Se_Railway train get held at Hither Green and another let in front of it? What is your signaller doing?!” We get asked this occasionally, not always so politely, so we sat down with Dan the ops man for Kent to find out. THREAD 1/

⚠️🚨 We're sorry to say the @Se_Railway #BromleyNorth branch is closed after this dramatic bridge strike on New Street Hill. You can see the girder and entire parapet have been knocked clear and it's unsafe to run trains. Importantly - it is also unsafe to pass under. /1

We're close to re-opening the line between #ShepherdsWell and #Dover Priory - here's what the tree did to the poor @Se_Railway train a few hours ago. This is why we take poor weather and autumn conditions so seriously. We'll update you when we know the line is open again.

VIDEO - we're really sorry for the delays to @SouthernRailUK and @TLRailUK on the Horsham line tonight. A defective joint on the live rail had to be fixed ASAP and this film shows why. It's all done now but knock-on delays are expected unfortunately.

We are working with the emergency services after an engineering train caught fire near Dunton Green, blocking both lines between Sevenoaks & Orpington. Fortunately no one was injured & we’re now working out how to move the train so we can get @Se_Railway passengers moving again

⚠️ Oh look. This is #Bickley on the Victoria/Chatham main line, it's our second trampoline of the day and the lines are blocked and power off. Trains affected are @Se_Railway + @TLRailUK . We've got a team on its way. #StormCiara trampoline count: 2 ⚠️

With the backing of @CHATmuseum, @lionelstanhope has created this mural on the bridge next to Charlton station, yards away from the Valley, home of @CAFCofficial. The mural also pays tribute to lifelong Addicks fan Seb Lewis, who sadly passed away due to #Covid19.

A few people have asked why we cannot just run trains through flood water. So here is a THREAD. Moving water above track level means there is already several feet of it below the track, in the ballast stones that support the railway. That movement can dislodge the stones... /1

Good evening. Trains are quiet but we know many people travelling are key workers and we and @Se_Railway @SouthernRailUK + @TLRailUK are enormously proud to serve you. Our Hastings line signallers work in mostly traditional boxes and are keeping it moving tonight. Thanks guys! /1

1/ A new look Gatwick Airport station is set to open to passengers on Tuesday 21 November, transforming the journey from train to plane and giving passengers travelling between #Brighton and #London easier, faster and more reliable journeys. A 🧵...

Exactly one year ago, at 4.36pm on 27 April 2017, this little bundle of cuteness was born at @NetworkRailLBG. Today, we welcomed him and his parents back to the station to celebrate with us. Happy birthday, King! x networkrailmediacentre.co.uk…

This is the opposite of everyone pulling together - someone dumped a mattress on the railway near Swanscombe and a @TLRailUK train has hit it. We are trying to get passengers evacuated as soon as possible so please hang in there. As for whoever dumped the rubbish, words fail us.

⚠️We're sorry for the disruption to @Se_Railway trains travelling into Charing Cross this evening. There's no easy way to say this, but we have a problem with a lubricator. It should be greasing the edges of the rails to stop wheels screeching and rubbing on sharp bends... /1

We are very pleased to unveil another in our series of striking station murals. Can you guess where this one is? (Artist credit: @lionel_stanhope ) @Se_Railway

One last look at the old London Bridge ASC, eh? Why not. The signal box and its signallers served us well over the years. The box was supposed to close in April and its signallers retire. But, they stayed on to keep the country moving during COVID. Hats off to them!

⚠️ The worst of the storm is reaching us and there is disruption on almost all lines with at least 14 trees down, along with this billboard at #ElephantandCastle. Do not travel. #StormEunice

Happy Boxing Day🎁! Here's a thread on some of the work taking place on the railway. In #Lewisham, South East #London we are rebuilding the junction at the London end of the station. It’s one of the busiest in the country, controlling more than a third of @Se_Railway trains.

Now here's a sight - a @SouthernRailUK cab ride through all 5 landslips near East Grinstead on the first train to run over the full line since early Feb (featuring the voice of our man Murdo, keeping a safe distance). We'll be open for key workers to travel tomorrow. /1

We’re really sorry for the ongoing disruption to @TLRailUK services north and south of London, owing to a problem with our signalling equipment between City Thameslink and Farringdon. Here’s what’s going on.../ /1

Now there's a sight for sore eyes! Thanks to @SouthernRailUK for their test trains over the Edenbridge landslip site today - everything worked and the line will open all the way through from Redhill to Tonbridge tomorrow. Thanks for your patience and enjoy the trains 🚈!

⚠️🔥 Sorry to say, no sooner had we fixed the points between #WaterlooEast + #LondonBridge than a fire broke out in an arch under railway. @LondonFire are on site with multiple pumps and we have closed the railway until we can confirm it’s safe. More as we have it...

⚠️ We’re sorry to @SouthernRailUK passengers for the disruption between #Barnham & #BognorRegis today. This lorry overturned in the early hours of this morning and went through the boundary fence of our signal box. /1

"Twas the night before #StormBarra and throughout the South East, railway neighbours were tying down trampolines." Terrible poetry, good advice. With winds over 50mph, please check before you travel tomorrow and don't leave your trampolines free.🍃🌪️

Sadly for @MrTimDunn , London Bridge signal box is closed, and he can’t take control of the railway! Great to welcome him to one of our favourite railway haunts as part of the launch of @YesterdayTweets #TheArchitectureTheRailwaysBuilt starting tonight!

📹New video montage illustrates examples of reckless behaviour and near misses at level crossings. 🚉As we approach the school holidays we've launched a campaign to remind children and their parents to act responsibly when near the railway this summer. /1

⚠️ We're sorry to say that @Se_Railway + @TLRailUK trains will be disrupted this morning by this cracked rail near #NewCross . We're working on a plan to run trains around the problem but it's not a normal rail, so it's not an easy fix. #TLUpdates /1 ⚠️

We're sorry to say the railway between Redhill and Edenbridge remains closed as this landslip is still getting worse. Our colleagues @SouthernRailUK have buses and trains running to keep you moving and our engineers are waiting for the site to become safe. /1

We will shortly be showing you some of what we're up to on your railway this Bank Holiday, but in the meantime , here's one of our team - Basil - on a track patrol near @Se_Railway's Grove Park station this morning. He's in orange but he's lost his hard hat. 🦊

Ever wondered what the driver sees? We joined the 0936 Victoria to Dartford service to find out!

Working for the railway involves more wildlife wrangling than you would expect, and we were pleased to be able to arrange the rescue of this poor fox, who became trapped under the live rail at #Caterham station. /1

Our test trains are still out and about making sure tracks are safe to run on - here's one just now visiting the site of the Edenbridge landslip, on a line usually used by @SouthernRailUK trains. Train fans will note the pair of Class 37s 😉

We've found the cause of the power supply problems on the route between #Rochester and #Swanley. Something has caused the live rail to arc to the running rail, and burned enough of a gap to rip the current collector equipment from passing trains (called "shoes"). /1

🦁You can't miss the Lions when you're in Bermondsey and you can't miss this one either! We're delighted to have worked with @MillwallFC + @lionel_stanhope on this fantastic mural on Zampa Road, paying tribute to the club and the community. More here 👇 networkrailmediacentre.co.uk…

❄️ We run anti-ice trains overnight and @Se_Railway run empty trains in the morning to keep the live rail free from ice and snow. However, when it sleets or snows on the clear rail, it can rapidly become impassable again for trains. This was #HitherGreen just now /1

Did you know our rails are date stamped? The rail stamped 1968 was cast by Colville in Scotland 51 years ago and lasted well until it was replaced on Sunday in Margate. The new rail code says British Steel Scunthorpe (20) 19. 1/

We’re really sorry to @Se_Railway passengers for the delays between Tonbridge and Sevenoaks, due to this trampoline being blown onto the tracks. We have response staff on the way to remove the object as soon as possible, so we can move the empty train and get lines open again

⚠️ Really sorry but we've had to block the line between Peckham Rye/Nunhead because of this defect. Looks like a train has locked its wheels (or possibly spun them) and damaged the rail, and we need to grind it back into shape and clamp it for safety reasons. #TLUpdates /1

This display is what the signalling control system at East Croydon should look like, but last night it was competely blank. It's where the electronic signals from the control centre at Three Bridges are processed and sent out to the tracks to move points and change signals. /6

❗️🔥We’re really sorry about the disruption passengers are experiencing in the Whitstable area due to a cable fire at the station. 👩‍🚒@kentfirerescue are on-site and the line remains closed for now. Please follow @Se_Railway for the latest travel advice.

Railway junction fans (yes they do exist and @GarethDennis + @garius we're looking at you!) this is a shot of our plans for rebuilding Croydon's railway, looking North to South across Selhurst. Find out more + take part in the consultation here: networkrail.co.uk/running-th…

UPDATE: You'll have seen plenty of coverage of this picture today and yesterday, showing the derailed train at #Tonbridge. Here's a brief overview of where we are and what we are doing, also why @Se_Railway are affected even though it's not their train... /1

Charing Cross station unveiled the first Network Rail water fountain in the country today. With almost 30m @se_railway passengers every year, it's sure to be popular and we hope to save hundreds of thousands of plastic bottles - if not more. @WaterforLondon

Barnehurst video updates: Our geotechnical engineer Derek Butcher explains what’s going on at #Barnehurst, why this is the 4th landslip since 2010 and how we’re fixing it #Bexleyheathline @Se_Railway 1 of 2

Folkestone Signal Box has some unusual alarms built in, as it controls the railway along the chalk cliffs. Rock falls trigger a warning system (3 buttons on the panel), so we can stop trains. Our geo-technics boss Derek took these shots - those rocks are his job! @Se_Railway

We thought it might help explain the challenge we face this afternoon if we put out the current list of blocked routes in Kent, SE London and our route into East Sussex via Tunbridge Wells... #StormEunice

Apologies to @Se_Railway passengers if you were delayed in the #Birchington area last night - our team were struggling to move this family off the tracks as mummy and daddy swan were very protective of their cygnets. Working for Network Rail requires a variety of skills...

If you enjoyed our #geekthread on the upcoming #HitherGreen engineering work, which marks the end of 46-years of signalling from this brutalist building at London Bridge, you might enjoy this mini-thread... /1

Yesterday @TLRailUK & @SouthernRailUK passengers had a really rough day due to a combination of incidents which impacted trains all day. We're really sorry for the delays, they were our fault. But you deserve a proper explanation, so take a seat and read more if you like 👇

There's a house in Gypsy Road, West Norwood, missing a children's plastic playhouse. If you're wondering where it is, it was on the railway. It is no longer on the railway. Please tie your garden stuff down! #StormCiara trampolines 2, playhouses 1.

⚠️ #StormCiara super-thread. We'll update this as the day goes on with incidents/advice affecting @Se_Railway / @SouthernRailUK + @TLRailUK until the winds die down. This is the Chelsfield trampoline as it was at 7am today - it has since been removed!

It’s Friday but we know that for many @se_railway passengers, it’s not been a happy one, after problems at #Lee and #Lewisham last night. Many people have asked us about #Lewisham so here is a VERY LONG THREAD with some colourful diagrams to leaven the technical detail. 1/

In fact it is unlikely we would have been able to run a service today either as every location would have needed to be repaired or replaced. So the systems worked as designed and saved us from a much worse fate. /8

👷‍♀️ It's smooth over the site of the Edenbridge landslip this morning - a big difference from when we had to close like last December. Thanks to @SouthernRailUK for the cab ride and @Butch1306 for the video. Not even a bump!

Railway folk know you can't wave red or green out of a signalbox so we made sure there were no trains around when we took the pic/video. With Hastings in Tier 4 there aren't many passengers about either but if you are travelling today - don't forget to wave! It's not all bad...🎅

A career in the railway is exciting and not ‘just for boys’. This morning at 7:42, Britain’s first ever all-female passenger service will run from @NetworkRailVic to Faversham as part of our support for International Women’s Day #IWD2020 #EachforEqual @networkrail @Se_Railway

Why is @Tony_Robinson wielding a massive spanner on the bridge at Charing Cross? Are @Se_Railway passengers aware we've put Baldrick in charge of maintenance? Find out what's going on @channel5_tv tonight at 8pm with The Thames at Night!

We are working as quickly as we can to open the railway at New Beckenham after a car got on to the line overnight. We thank all passengers for their patience during this time and we are sorry for the impact this has had on their journeys.

⚠ UPDATE: Derailed train at #Robertsbridge After yesterday's low-speed derailment of a freight train on the Hastings Line near Mountfield Tunnel, our teams have been working round the clock to re-rail the stranded train (📸pictured on the right) and get passenger services running back on time. So why couldn't we fix it last night? Initially, we hoped to re-rail the locomotive overnight and restore full service by this morning. But due to the wagon buffers being under compression (meaning they were pressed tightly together), and the need to move the wagons back by at least 1 metre to create enough space for the teams to work to lift the train back onto the rail, it simply wasn't possible without risking bigger delays today. Instead, engineers were able to carry out all the significant preparation work last night. We're now planning to proceed with re-railing the locomotive tonight so we can reduce the disruption to passengers. We expect the re-railing to take between 5 and 8 hours, and there may be some extra repairs to do to the track to make sure everything is ready for Wednesday morning. @Se_Railway services are still running today but to keep everyone safe, we've got passenger trains running at a slower speed of 40mph past the freight train, which is delaying trains by around 5-10 minutes. We’re really sorry for the inconvenience this is causing and thank you for your patience and understanding. Our teams are working as quickly and safely as possible to get everything back to normal. In the meantime, please checking with @Se_Railway for the latest updates and advice. 🙏

Is it a bird? Is it a... well you get the picture. Amazing street artist @lionel_stanhope has worked with us to create this artwork in Cornwall Road, under @Se_Railway's Waterloo East station, London, to say Thank You to our #NHS heroes. More details 👇 networkrailmediacentre.co.uk…

ℹ️ We're aware of a slow speed collision between a train and a car at Grove Ferry level crossing. 📷Thankfully there are no reported injuries and our front line responders are working with @kent_police @BTP to remove the car from the crossing. /1

Interesting addendum: when working at Ashford, everyone has to stay at track level because platforms 3+4 are International and if you find yourself up there you'd better have a passport and good excuse.

Finally, we can only apologise for the disruption last night, as we know what a huge impact it had on everybody. When the full investigation is complete, we will let everyone know what it finds (beyond what we know so far) and how we will make things better in future. /13

Here’s the rather surreal scene currently...

UPDATE on Sundridge Park - work to clear debris and build a scaffolding crash deck is underway and pedestrian access should be sorted by around 2130, with full road access by around 0130. We aim to have @Se_Railway running trains by first thing tomorrow morning. Thank you.

❄️ There's lots of snow and ice around so please check before you travel and take care while in and around stations today. Don't be like the driver of this car, who abandoned ship on the railway near #StoneCrossing last night and wasted emergency service time and people. Thanks❄️

⚠️We're really sorry for the delays to @SouthernRailUK passengers this morning due to two incidents which are causing disruption. ⚡️The line from Portsmouth Harbour to Barnham is blocked after an incident involving the conrail - the electrified rail which powers trains. /1

A UPS at a nearby location actually put itself into "bypass" during the spike, which suggests it is not a clear-cut answer. Another important part of the investigation is why we cannot remotely reset signalling control points, and how quickly that can be rectified. /11

UPDATE: We are closing all routes in Kent, and all lines in SE London are blocked by trees. Please do not travel. We will reassess the risk after 1500 on a line by line basis but it is no longer safe for our staff or trains to run. Thank you. #StormEunice

After a wild weekend, where we estimate 20% of all leaves came down, it's very slippery out there and trains will be slower to accelerate + brake this morning. We're running our leafblaster trains to keep things moving, but it's still tough out there. Thank you for your patience.

I guess this is goodbye... After 45 years of signalling trains, London Bridge signalbox is silent, thanks to an £81m scheme going on at #HitherGreen this week. More on what, where and why here ⬇️ networkrailmediacentre.co.uk…

Our friends at @GBRailfreight have been running Snow and Ice Treatment trains all through the night to keep @Se_Railway and @SouthernRailUK / @TLRailUK passengers moving this morning amid the snow. Here's two of their locos in a blizzard last night. Thanks guys!

⚠️ Here’s the trampoline that is currently disrupting services towards London, we are working to remove it but will need further staff to assist given its size. @Se_Railway will continue provide the latest travel information between Orpington-Sevenoaks. ⚠️

Please get comfortable as this is a long thread from our MD John Halsall to explain what’s happened at #EastGrinstead and what we’re doing to get it fixed. Here goes… We've had a landslip near East Grinstead station, so it’s not safe to run trains @SouthernRailUK @TLRailUK

The power supply to our signalling in this area had a power surge, what is known as an Over Volt, for 20 seconds. This is an unusually long time for that kind of surge and many different systems - some only 18 months old - all shut down to protect themselves. /5

WATCH: Meet the team who spent Christmas in the dark, with cold water pouring on them. Yes, it's everybody's least favourite worksite - Sevenoaks Tunnel. #ChristmasBHWorks

Today was a big day for us, @SouthernRailUK/@GatwickExpress and @TLRailUK as we saw the first trains run into the rebuilt, bigger and more accessible platforms 5+6 @Gatwick_Airport ! Thank you to everyone who made it possible.

...but it has got overexcited and has let all its grease out in one go. Trains have been rolling through the grease near Waterloo East and finding it very difficult to stop. /2

Good news. We’re on the home stretch for the #Bexleyheath works. On top of the landslip protection work, we’re doing extra stuff like freshening up waiting areas, repainting, new platform surfaces, deep cleaning, clearing gutters, fixing shelters and litter picking. @Se_Railway

We can only apologise for what was a terrible evening for our passengers, who took hours to go home and in some cases missed flights from Gatwick Airport. Many of you asked us how this could happen - so this is what we know. /4

⚠📹CCTV shows the moment a pair of riders on a small moped dodged barriers at a level crossing near #Littlehampton. Narrowly escaping being struck by a train travelling at up to 70mph! If you hold any info please contact @BTPSussex texting 61016, quoting log 411 of 21/02/23.

Is there anything worse than corporate Twitter accounts' Valentine's Day poetry? Roses are red Violets are blue We laid 570 yards of track at Haywards Heath this weekend For you. 💘 How was that, @SouthernRailUK ?

Why don't we have Uninterruptable Power Supplies? Well, we do at some locations, such as signalling centres. What we are not sure of - and are investigating - is if a UPS at each location would have stopped this or if the voltage spike would have put them offline too. /10

So what is next? We are working with our operator colleagues to investigate the disruption, with @UKPowerNetworks to learn more about the power surge + our many signalling suppliers about how we can make our kit more resilient to this kind of event. /12

This train was the first @TLRailUK to run automatically in passenger service - and the first on our network. A big day for @TLProgramme !

A sight to make @Se_Railway passengers (and us!) happy this morning - the first train signalled over the new kit at #HitherGreen and the new computer controlling it all at Three Bridges. Thank you to everyone for your patience after our 9-day project to make it happen.

Anti-ice trains in Tonbridge getting ready for their evening departures to run around Kent. It's bloomin' cold!

We visited our landslip at Godstone today, which is still affecting @SouthernRailUK passengers, and the bad news is the ground is still moving. In fact the other track is now at risk too. This picture shows holes starting to appear closer to the Redhill-bound rails. /1

Right then, we've had some sad people make life difficult for our colleagues and passengers today (⬇️) but that has passed so we are now going to do a thread of railway positivity and all the good stuff people are doing out there while some of us are in isolation. /1

We're hard at work this Bank Holiday weekend, installing our new bridge at #Catford and replacing points at #Crayford 🛠️ The old bridge at Catford dates back to around 1890. We're replacing it with something a bit more modern, as you can see in these pictures 🧑‍🔧

Barnehurst update: We've completed the emergency engineering works at #Barnehurst today and test-run trains successfully, which means the line will be open again tomorrow morning. Thank you once again for your patience this week @Se_Railway

Is it a bird, is it a plane? NO! It's another Super Thread on obscure railway engineering inspired by this delivery from the skies last week (at Lee in SE London.) This one is about the power that gets @Se_Railway , @TLRailUK + @SouthernRailUK trains to move. /1
