⚠️🛤️ We've had reports of a potential track problem between #Gillingham and #Templecombe on the @SW_Help West of England line. The line is currently blocked awaiting the arrival of a mobile operations manager, who can examine it to see if it's safe. Apologies for the delay.
UPDATE: We have a team on its way to site and the next train through will take it slowly and examine the track for any problems.
UPDATE 1825: this is the issue between #Gillingham and #Templecombe . Our track team is on its way to see what work needs to be done to reopen the line, which is now blocked (for obvious reasons). Thank you for your patience and please follow @SW_Help for travel info.

⚠️We're really sorry for the disruption @SW_Help customers are facing today. Early this morning a train struck an object in the Walton on Thames area. While no one was injured and all passengers were safely escorted from the train, the lines are blocked while we investigate. /1
Early investigations show the front wheels of the train have derailed 👇 so it's likely to take us some time to get the railway open. We'll keep you updated on the repairs & timescales for reopening as soon we know more. Please keep checking with @SW_Help for the latest advice /2
Here's an update on our plan to get the railway back up and running for tomorrow morning.
It might not look like a big job, but first we've got to get the train's front wheels back on the rails. Our 'rerailing' team are on site now deciding on the best way to do that /3
⚠️VIDEO: A major landslip has damaged our main line, just outside of #Hook, in Hampshire.
📢@SW_Help customers are being advised not to travel tomorrow if their journey is to or from London to the south or west of Basingstoke.
Here's route director Mark on what's happened 👇 /1
This link takes you through to our press release, which has more details. networkrailmediacentre.co.uk/news/video-maj…
TLDR? We will summarise it in a few Tweets on this thread. /2
A 44m section of 10m-high embankment, built largely of London Clay in the late 1830s, has slid out from underneath the railway, leaving one track in mid-air.
It's also exposed the ends of the sleepers of the track next to it (sleepers are what rails are fixed to) /3
UPDATE on #Haslemere broken rail for @SW_Help customers.
We have teams on their way to site to disconnect signalling equipment around this joint and cut the offending section out.
They will then rebuild the joint with fresh rail, reconnect the signalling and reopen the line/1
As it’s an insulated joint, it’s part of the signalling system too, and will require testing before we run trains.
Our train detection equipment in the area uses low electric currents run through the rails, and the insulation keeps the currents apart. /2
For that reason it will take us at least until 1530 today to get the job done and we advise customers travelling between London Waterloo and Portsmouth/ Weymouth (and reverse) to avoid travelling if they can.
Please follow @SW_Help for ticket and travel information. /3
⚠️🛤️ We’re really sorry to say a routine track inspection has found a broken rail at #Haslemere (pictured) on our diversionary route for @SW_Help passengers heading to Portsmouth, Southampton and Weymouth (the main line is blocked by engineering work around Hook). /1
We are unable to run trains over the crack in the picture as its location means it could cause a derailment if the rail was to come apart under a train.
For that reason, Portsmouth and Weymouth services can’t run to London until we can fix the problem. /2
We’re planning our response now and once we’ve got a plan and resource in place, we can give an accurate timescale for when we can get the line open again.
The crack sits in an insulated rail joint, which means we can’t just clamp the rail and run trains slowly /3
⚠️🚦 We'd like to say how sorry we are for the continued disruption to @SW_Help customers between Yeovil Junction/Crewkerne and Exeter due to a signalling problem which means we've been unable to signal trains in a 35-mile section of railway. networkrail.co.uk/running-the-ra…
The railway is divided into sections where only 1 train can be. The system knows if a train's there thanks to two forms of tech, track circuits and axle counters. Axle counters spot changes in magnetic fields when a train wheel passes by to literally count the wheels on a train.
Despite lots of testing on the axle counter system since it failed on Sunday morning, including replacing multiple components and calling in experts from the manufacturers, we've been unable to find the cause of the fault. So we need to reset the system which can take a few hours
