It looks as though this is going to be a trend this week. Three derailments now.
And let me take this opportunity to ask people to please use relevant other threads to discuss other incidents thank you :)
Edit: such discussions can now be found in the following thread:

If you include Redhill - Tonbridge that suggests that the SER were doing the same sort of thing as the LBSC.
And if you look at some of the GWR earthworks of the early 20th Century, so were they - I'd be surprised if any weren't

BBC interviewd a passenger at length who was very clear, and suggested part if the delay in evacuation was because of the electrified tracks.

BBC news channel interviewed the Industry editor of RAIL, who said he didnt think the line was electrified. He may not know the network well, but surely he can recognise an ELECTROstar, one of the commonest types on the network.
Good grief!

Might be mis-reporting, the interviewee may have been explaining that power had been turned off for the evacuation?

A friend of mine was one of the very first responders at Grayrigg in 2007 and he said it took far too long to get confirmation that the electric Overhead was off and would stay off. I trust the process is improved nearly 20 years on

I don't think that's the case - in the photos posted early in the thread it is possible to get a good iead of where thet vehicles went after leaving the rails and, to me, it looks like they simply managed to avoid most of that vegetation.

In this image you can see quite a bit of flattened/dragged vegetation where the carriages obviously went after going down the side of the embankment and prior to coming to a halt, and at extreme right you can see what looks to be quite a large flattened/uprooted tree underneath the carriages.

This has been going on for a long time. A problem that was discovered at the Newton collision in the early 1990s where the overhead line equipment was ‘confirmed’ as ‘off’ but it was subsequently discovered that longer distance ‘bare feeders’ suspended from the outside of the masts were still ‘live’.

I had a job 10 years ago, BTP already on scene at the incident site which was a short walk from a platform.

We were holding back until NR staff came to give us the ok to proceed. We were then given a list of places we could be, and a list of places we must not be.

The delay in access as a result of this would have had absolutely no change on the incident outcome, but it was interesting to see the difference in access policy between services.

If an "Emergency Switch off" had been requested (and agreed by the ECR - not all are), the procedure is to drop the feeder breaker to open the section to the midpoint. This would also kill any bare feeders/ATF. Of course that's not an Isolation (with Earthing) which would be effected somewhat later so there may still be some residual charge in the conductors until then.

I'm rather surprised by that; During my time as a Controller we had clearly defined processes for liaising with the Electrical Control Rooms and the Emergency Services, and specific forms of words to use for the latter, depending in whether the overheads were earthed or not.

That was down to human error, IIRC.

[Re Newton isolation error]

Well, yes. But if “human error” can lead to emergency personnel with ladders potentially getting electrocuted it does emphasise the importance of obtaining absolute assurance that all live equipment in an area has been isolated and earthed.

Cross-posting from the Wickford thread. Network Rail has a released a full, detailed statement on both incidents.
Network Rail has issued the following statement regarding the derailments in Lewes on Thursday 13 August and near Wickford on Friday 14 August.

Martin Frobisher, Group Safety & Engineering Director at Network Rail, said: “We are currently responding to a derailment incident near Wickford station in Essex, and we are working quickly to understand the situation and to provide assistance where needed. Two carriages have derailed but remained fully upright, and there are no significant injuries reported.

“I appreciate the public will be concerned at the news of two derailments of passenger trains over a short period of time, but I want to reassure them that Britain’s railways still rank among the safest in the world, and that safety is always our first consideration on the railway.

“Our thoughts remain with everyone affected by yesterday's significant incident at Lewes. I want to thank the teams from across the rail industry and emergency services who have been working around the clock to provide assistance and support to those who need it, as well as the response from the local community.

"The Rail Accident Investigation Branch is conducting an investigation into the derailment at Lewes, and has investigators on scene at the Wickford incident. We would ask people to avoid speculating on the cause of any incidents until further information is available. We will also conduct our own internal investigations, in which we will look at all possible causes and factors.

“The unprecedented hot and dry weather that we have experienced this summer has presented exceptional challenges to the railway. In response, we have taken several additional proactive steps to manage and mitigate the impact on the railway, including closely monitoring the temperature of tracks, implementing speed restrictions where it is appropriate to do so, and planning track renewals around high temperatures.

“Our continued focus remains on supporting those affected by these incidents, working at pace to understand the causes, and doing all we can to get services back running safely as quickly as possible.”

Notes to Editors
On international comparisons, Britain remains one of the safest railways in Europe and the world. The Office of Rail and Road’s Common Safety Indicators rank Great Britain:
Top 10 in Europe for passenger safety risk (fatalities and weighted serious injuries per passenger train-km): https://dataportal.orr.gov.uk/media/53gnbh44/common-safety-indicators-2024.pdf
1st overall in Europe for whole-system rail safety risk (covering passengers, staff, level crossings, trespass and wider societal harm): https://dataportal.orr.gov.uk/media/53gnbh44/common-safety-indicators-2024.pdf
The investigation will look at all relevant inspections and reports to rail industry from customers.
Reports of bumpy journeys are not uncommon on the railway and they are always followed up with an inspection.
Network Rail is fully cooperating with the Rail Accident Investigation Branch's investigations and it would not be appropriate to speculate whilst those processes are ongoing.

Appears the line between polegate and willingdon junction is shut today (Saturday), reportedly due to buckled rail. Obviously caught that one in time. Eastbourne services from Brighton terminating at Polegate VVAR

Statement from Heidi Alexander to reassure and re-emphasise the safety of the rail industry:
"I am thinking of those affected by the derailment in Lewes yesterday, as well as those involved by today's derailment in Wickford. The Rail Accident Investigation Branch has been deployed to both sites and is expected to report on the causes in due course. It is important that we do not speculate in the meantime."

"I understand passengers may be concerned about news of two incidents on the network, but the industry has been taking proactive steps to manage the heat for example by closely monitoring track temperatures and putting speed restrictions in place where needed."

"This afternoon, I spoke with Network Rail and other industry partners, including those on the scene at Lewes, to seek assurances that everything possible is being done to avoid similar incidents occurring."

"Our rail network is amongst the safest in the world and whilst incidents like this are thankfully extremely rare, when they do occur, they are taken very seriously."

"Safety is our absolute priority. The industry will ensure that all lessons are learnt and I continue to be briefed on the operational response."

With this being third rail, surely the whole stretch would have been off as a result of multiple short circuits?

Also, on the subject of decency in reporting, I've found the interveiws of passengers reliving their experiences, complete with camera footage of events inside the carriages in the immediate aftermath, far more uneccessariky mawkish than anything that happened with the helicopters and breaking news.

I’ve seen people saying they’ve been on that section of track where the train or other sections along the East Coastway line where it’s been rough and the train violently shakes about, could this be because of the suspension is bad/the design of the Electrostars is poor (sorry I don’t know the actual terminology ) rather then the tracks causing the train to violently shake about?

I’d say it’s a bit of both. I can remember it always being a fairly rough section in Mk1 days, especially when passing over level crossings, however the Electrostars do tend to accentuate jolts especially if sitting at the vehicle ends.

On the various GN routes, the 387s rode noticeably rougher compared to 365s.

Sources close to the recovery operation indicate that lifting will occur on Wednesday.
Ah fair enough, I presume this will be involving outside ‘industry partners’, with minimal involvement of the breakdown gang? (Presuming the breakdown gang is still a thing, it’s been a few years since I was on depot and part of the gang)

Yes indeed, led by VolkerFitzpatrick/VolkerWessels mainly.

NR Sussex Route Director has a video up on twitter where she confirms RAIB have concluded investigations and its back with NR Also shows they have an access road upto the train already installed so looks like lift out via road maybe.

We now begin the next phase of the recovery operation at #Lewes, working alongside our industry partners. Today's site update from Lucy McAuliffe, Network Rail's Sussex route director.

New update from NR

https://www.networkrailmediacentre....days-as-major-train-recovery-operation-begins

The railway between Lewes and Haywards Heath will remain closed for at least another ten days while teams recover the derailed train and begin repairs to the railway.
The Rail Accident and Investigation Branch (RAIB) completed its work on site on Saturday and has now handed the site back to Network Rail. RAIB’s investigation into the derailment continues.

A complex recovery operation is now under way. Three carriages derailed and slid part-way down the embankment. These will need to be carefully lifted away by crane.

The location makes this particularly difficult. The railway is close to a river, in a Site of Special Scientific Interest, and restricted road access is only via a residential area. As much specialist equipment as possible is being brought to the site by rail given the challenges of access by road.

Engineers are now preparing the site for two 125-tonne rail-mounted cranes, among the largest cranes available for use on the railway. Before lifting can begin, teams must make sure the ground and railway are stable and strong enough to safely support the cranes and the weight of the carriages.
So this suggests they are using Kirow cranes similar to Elstow and teh coaches will be moved somewhere else if they cant be moved by rail.

So lifting 3... judging from the earlier pictures they will have to re-rail at least one more as well. The other 4-car Multiple Unit might be drivable out under its own power if re-railed. Slowly and carefully ofc.

... but only if the 3rd rail can be re-energised, which I doubt will happen for a long time yet. Rescue loco needed!

Front four will be off to Stewarts Lane on the back of a loco. Rear four will be recovered one vehicle at a time by a pair of K1200s to a level crossing north of the site for onward transport by road.
