They ran three Thameslinks (9J56/58/60) up through Hitchin to Peterborough after a hefty delay so they have the potential to implement SLW via the emergency crossovers at Biggleswade to clear some of the backlog to avoid stranding so many people but industry no longer practices that.

I'm surprised they don't cape 1Y20 to free up another one. The set should actually end up in the bay at York tonight (P7) and it clearly isn't going to go to KGX and back now, so could they just shunt it into there?
Not tonight it shouldn't. 1N35 2308 off London was booked to terminate Doncaster and outstable there due to Doncaster-York being unavailable. 1Y01 would then commence there.

In addition - 1Y20 was altered to terminate at Doncaster tonight (with 1N35 cancelled) due to a fault with the set.

For any armchair crayonistas looking at ways of fixing the Welwyn bottleneck (due to which these disruptions keep ruining the whole south ECML not just either the fast or slow lines), may be worth rethinking a tunnel. More expensive, sure, but mostly safe from the constant weather or trespassing issues :)

A tunnel all the way from Hitchin to Belle Isle possibly. But it isn’t really Welwyn that is the problem at the south end of the ECML, Hertford is available to bypass that (albeit with the difficult choice of whether to temporarily sacrifice the local service for the greater good, as was done after Hatfield and Potters Bar). Stevenage-Hitchin is more disruptive, and it’s notable how many incidents occur in this section. Stevenage in particular seems to have become a hotspot for fatalities.

From a resilience point of view, one wonders what the cost/benefit ratio would be for
* replacing the headspans between Langley Junction and Hitchin
* devise a way of having segregated run-through platforms at Stevenage, either have all stopping services on loops, or allow passengers on the platforms only when a stopping train is immediately imminent

Ah, OK. Given the fault I'm surprised they haven't run it down to Donny and then back to NH.

GTR just don’t do this, their response is just to pull down the shutters (literally in the case of some of their station staff, in my experience).

There would be drivers at Peterborough, even just one train shuttling as far south as possible would help avoid stranding people.

Instead of recruiting 100 travel safe officers to mill about talking on their phones, first priority for GTR should be to get their control function to a state where it has the resources to handle disruption. It’s completely unsatisfactory just to close the shop for the day when something happens.

Cambridge and Kings Lynn seem to manage to collaborate to provide some sort of service on the Fen Line section when disruption happens, albeit a bit patchy sometimes, the rest of the network just can’t seem to ever do anything.

The Thameslink site says ticket acceptance is in place with Arriva for local buses but doesn’t mention that the last 97 bus from Hitchin to Letchworth left around 6pm. There is a slightly later 55 from Stevenage to Letchworth.

Back on topic, 1B91 from Lincoln to London has departed Peterborough. AIUI the Up Slow is available for traffic again so we should see a trickle of services heading into London now.

What I was should have said is LNER could have come as far South as Biggleswade then SLW over Down to Stevenage. OK one or two trains an hour is all that could be achieved but it gets some people to destination. Mind you a 12 car 700 could shift even more people!

I thought something must be open when they started sending things south from York again. Thanks

I got to Peterborough at around 19:20 (off an EMR service from Norwich) and it was mayhem, people heading south were being directed to stand outside the station to wait for taxis to complete their journeys, whilst those of us heading north (Darlington for me) had to wait for instructions as to how we could continue our journeys, first they announced anybody heading to York and Newcastle to get on the Lumo train on platform 1 (I figured I'd take this to York then try and get something from there), after some more mixed messaging and confusion, it was later announced that an LNER service would be leaving from platform 2 calling at Grantham, York, Northallerton, Darlington, Durham & Newcastle so I caught that instead.

1Y20 terminated at York so the Guard could then be better used for something else to move more people, given 1Y20 was only going to be able to go to Doncaster anyway.

5Y20 then ran York - Doncaster - NL

Making matters more miserable in this particular case of ECML disruption...
Due to the displacement of our train stock as a result of this evenings incident, our morning services will likely be disrupted. Please check before you travel in the morning and be prepared to allow additional time for your journey.
It appears that the situation will not improve overnight, and that morning rush-hour travel will be disrupted. Fantastic, seeing as that will be on a Tuesday when the most people will be travelling in; you'll have both the usual Mon-Fri crowd, but on top of that there's the hybrid crowd who usually go into offices on Tuesdays. This will be an absolutely miserable morning of disrupted travel right before arrival into the office. And of course, with half term having just passed, this will be the sort of time where the country collectively goes back to work, and you'll have far fewer people taking annual leave etc. Expect pandemonium come 8am.

You'd think that, seeing as they have a good 6 hours or so before the morning rush starts, they'd have some time to put some rolling stock in the correct place overnight for the following morning's service...

Ah yes ...they can just use the legions of staff they employ to sit around all night, every night across the full length of the country just in case they need to reposition their entire fleet at the drop of the hat.

'A good 6 hours'... between (say) 2300 and 0500?

Spare staff are rarely available at those times to move units 'as required', as they're not when services are planned to run.... spare staff are placed where they can best assist the planned service, if (a normal level of) disruption means they're required, to mitigate the impact.

As someone involved in the incident today, and who generally has both sympathy and empathy for the effect of disruption on customers, the comment in the post above just isn't realistic, due to that and also other potential factors (route (un)availability due to engineering work, the necessity for each unit which isn't planned to outstable, to recieve a planned exam/fuel/CET empty at end of day, etc etc)

The message from LNER above regarding Tuesday is realistic though; firstly any misplaced trains will have to be fed back in to the diagrams ASAP, and secondly, throughout the day, crew who have got back many hours late today may not be available for the start of their duties tomorrow: there are (limited) spare crew available at those times, but not enough to cover everyone who may have been affected, given the scale of the disruption.

GTR. Can’t recover their service if an incident happens in the morning by the evening peak, so they would have no chance in this kind of incident. LNER will probably have a few cancellations. GTR will be awful.

LNER actually doesn't look too bad today.

  • 1E01 and 1E03 Edinburgh-KGX are starting from Newcastle
  • 1S08 KGX-Edinburgh starts from Newcastle.
  • 1Y04 Newcastle-KGX cancelled.
  • 1Y01 Doncaster-KGX cancelled.
  • 1D05 KGX-Bradford starts from Leeds.
Two other trains are 5-car vice 9-car.

A GTR has just moved out of platform 2 onto the flyover line. So power available on that line.
Doesn't seem to be anything else moving just yet...

Edit - 1P88 just departed Hitchin on down slow towards Peterborough.
I'm confused, who are GTR? I cannot find them on a list of TOC's. I have found TSGNL and TFGO.

TSGNL are continuing to use GTR (now standing for Greater Thameslink Railway) as a public-facing name for the overall operation.

This certainly involves a great deal of effort, but it is by no means an insurmountable problem. The key word is flexibility: flexibility in the deployment of rolling stock, in the deployment of staff, and in the infrastructure. However, all of this also requires a high degree of cooperation and standardisation between the TOCs and between the TOCs and the network operator (bidirectional signalling, rolling stock and staff freely deployable on many routes). If trains can be deployed flexibly and staff can also be deployed flexibly on these trains, things become much simpler. Fragmentation and bespoke solutions are the opposite. At the end of the day, it doesn’t matter which train is available the next morning for a particular service. The only thing that matters is that a suitable solution is found.

To a degree it very much does - though more in the sense that units are supposed to cycle through a depot for exam every 48 hours, and that you need the right type of unit (electric, bi-mode or MK4 set) on the right diagram, or you need a follow-up plan to correct things at the earliest opportunity. Fuelling (where applicable) and toilet tanking also need doing at the earliest opportunity if a unit hasn't made it onto the right depot overnight, so if you just put any unit on any working you quickly have a much larger mess to untangle.

Considering how catastrophically the job stopped last night and how late units were rocking up on depots (or at the wrong depot) ite testament to the work going on behind the scenes to put things right when there were only a handful of alterations this morning.

Of course, as you say, sometimes it doesn't necessarily matter with some services. The 2333 London to Leeds last night managed to run with a MK4 electric set instead of a five-car bi-mode Azuma, and ran direct via Wakefield rather than the planned diversion via Methley Junction, which isn't electrified. I suspect this was also motivated by the need to have that set on Neville Hill Depot, which is the only depot where MK4s are now maintained.

Northbound was a bit of an extended mess for a while after the event for GTR, mainly for what I could see due to cancelling trains at Letchworth which meant trains - including Peterborough services - were held back in each signal section through to Stevenage.

The purpose of my post was to highlight the importance of flexibility in the event of a disruption. Many of the problems you mentioned do exist, but they are not laws of nature; rather, they are problems that have been created over decades. The very idea of a ‘wrong depot’ for example might seem very alien to many TOC outside GB.

No doubt. However the financial/resource constraints of operating railways in GB would also seem very alien to many TOC outside GB.

I don't have the date. But to me it looks more like the difference between a short sighted view and a long term view regarding spending money. Every TOC is very tight with money these days. That includes TOC in public hand, they have a tight budget too and are not free to spend unlimited amounts of money.

To add a couple of things to the above;

. Of the list of full and part cancellations for today above, 1Y01 & 1D05 were actually due to a wiper fault on 91130 yesterday (following a bird strike, which by nature couldn't have been predicted), rather than the issue at Hitchin. The MK4 came back out of Neville Hill after repairs to start 1D05 at Leeds, and work the rest of the diagram.

. The MK4 on 1D36 (to get back to NL, partly to balance that fleet, partly for a loco exam, and in any case a need to run the last service) was a good example of the teamwork which some people are calling for above; it was picked up early by an experienced person at LNER as something which needed resolving, but with a risk regarding the route availability. A similarly experienced Controller at Network Rail arranged to amend the possession times to enable this to run via the West Riding, with the MK4; this also meant route knowledge issues with the planned diversionary route were mitigated by running via West Riding instead, given the crew displacement and the fact that not 'everyone signs everywhere' - again, this proteced the last service, which is a fundamental where at all possible.

Also not mentioned in this thread yet; after Hitchin had occurred (but at the same time that it was going on), there was a seperate incident involving multiple track circuit failures at Doncaster. This also resulted in uncertainty of route availability, and further ad-hoc amendments to the overall plan, affecting the same teams who were already snowed under.

My point here is every Controller makes hundreds of similar decisions in a shift like yesterday, both individually and as a part of the wider team(s) on duty, and some of which have to be revisions to decisions previously made and communicated, as circumstances change - the majority of these discussions and decisions might not be obvious from outside, because by nature any Controller is looking to avoid or mitigate a problem, and a problem which doesn't actually happen, sometimes isn't obvious....

Those who say that it should be better and reference political decisions made (e.g regarding unit flexibility) do have a point.... but it isn't something the teams on the day can influence too much; generally there's a set of rules which must be adhered to, and any wiggle room within those is known about and utilised.

In the meantime, spare a thought for the customers who will have been disrupted yesterday (and to some degree, this morning), and the staff, some of whom will have stayed back to help, and/or been very late getting home after a(nother) difficult shift, slept less than they'd like, and back in again today.

More fundamentally though is there needs to be a national standard/policy across all GBRs operations about how to deal with disruption. Currently, as we saw last night, even when part of the infrastructure is still available we wont or cant use it in degraded mode. Now I acknowledge that there are lot more issues that have to be considered compared to BR but that doesnt stop a revisit of the now esoteric task of Single Line Working for example being looked at what it takes to make it deliverable or not.

Then there is policy of complete withdrawal of routes not even part running them when most of the route was still available all actions BR would have implemented.

Conversely maybe the strategy of just accepting its a lost cause and concentrating on getting everything square for the following day is better especially in todays world where rolling stock and crew resources are so closely matched to the base service.

Anyhow nothing is a quick fix and the BR way is long gone and not coming back but it doesnt stop the question being asked can we do better for passengers in these situations its not as if they are rare!

I still haven’t worked out how it works or why it still exists at all. Even when I started at SBB 30 years ago, we no longer had a method in use that was anywhere near as complicated and slow. Today, it is estimated that more than 95% of lines are equipped for bidirectional operation. Even the few lines without bidirectional operation can be used with signalling and without paperwork.

Yesterday, a points failure occurred on the busiest section of Switzerland’s east-west axis, resulting in a reduction from two to one usable tracks. After the usual “chaotic phase”, a plan was drawn up (or rather, a pre-prepared operational plan was retrieved from the electronic “drawers” and adapted). Thanks to this plan and a modern, flexible signalling system, 17 trains per hour were able to run over this single-track section. Theoretically, more would be possible if trains were run in groups. Naturally, staff and rolling stock deployment also had to be adjusted accordingly. Thanks to the regular timetable, the scenario was repeated every hour with only minor adjustments.

The advantages of sustained investment in infrastructure over many decades. There are still lots of lines over here in GB, including mainlines like the ECML, where there is no bi-directional signalling at all or it is only very limited (with much longer signal sections and reduced line speeds).

The passengers and staff on the last Grand Central Sunderland to King's Cross yesterday evening must have been pleased to finally arrive in London just after 0100 this morning, some 4 hours and 1 minute late. As the traincrew lodge overnight, naturally as a result the first northbound service back to Sunderland this morning was cancelled, with (presumably) another driver taking the stock north as ECS from wherever it had been stabled.

Was that delay the longest to a service involved in this disruption that actually completed it's scheduled journey yesterday or today?
