Northern City Line Signalling Upgrade

[@normanprice7343]

Geoff! I work as a part of the East Coast Digitalisation Programme and may be able to help you make contact with a few of the people involved with the First in Class fitment of a Class 66 Freight Train at DBCargo's depot in Doncaster. The people there are lovely and would no doubt be more than happy to provide you with some insight into how ETCS will be affecting the Freight community (maybe even set you up with a depot visit to see where the magic happens)!

[@bfapple]

Yes I’ve heard some interesting things about how different the locos will be to drive under ETCS.

[@manomaylr]

ETCS operates within a wider framework known as ERTMS (European Rail Traffic Management System). Once the Northern City Line is ready, the rest of the East Coast Main Line from King's Cross to Stoke (between Grantham and Peterborough) will be upgraded to ERTMS (with a long-term vision of ERTMS all the way to Edinburgh). Then the legacy line-side signals will be removed too, so all trains operating will be required to be ERTMS-equipped. One of the biggest benefactors of the East Coast Digital Programme, as it's called, will be the InterCity operators LNER, Hull Trains, and Lumo. Their Hitachi (Azuma, Paragon) trains will be upgraded to run at 140 mph rather than the current 125 mph. There are no plans to fit ERTMS to the InterCity 225s, which means, as things stand, they will be phased out before the line-side signals are removed.

[@bfapple]

Not quite enough. 140mph operation also requires OHLE upgrades, level crossing closures, fenced platforms e.g. Biggleswade and St Neots.

[@manomaylr]

​@@bfapple That's true. The Mark 3 OLE used on the ECML was designed for speeds of 100 mph, not even 125, let alone 140. It's why the ECML suffers from frequent dewirements - the OLE is completely overwhelmed with so many high speed trains using it at the same time. Headspans are the main culprit, and the masts are also much further apart than the WCML. However, rebuilding the OLE is by no means an easy job. Level crossing closures is a long term goal, which should hopefully happen anyway. However, if we think realistically here. It's not like being hit by a train at 140 is significantly less survivable than being hit by a train at 125. Both will kill you instantly. Barriers on the fast lines make sense, but Potters Bar for instance has trains passing at 115 mph without barriers, and I've never seen anyone get pulled too close there. However, the main point I was making was that the fitment of ERTMS will remove the most major obstacle to 140 mph running. When the InterCity 225s came out the lack of in-cab signalling was the primary, if not the only, reason why they were limited to 125 mph in passenger service, despite being tested at 140 mph.

[@manomaylr]

@@bfapple There was an incident some months ago when the Thameslink semifast, which runs fast from Potters Bar to Finsbury Park, got horribly late, and ended up stopping on the fast line platform so it could make up some of the time (and to avoid getting stuck behind the all-stops service which had by this time gone ahead of it). With fencing on the fast lines, this would not be possible (though it is possible to fit sliding fence gates like those at other stations). The next time the train got that delayed, the train stopped on the slow platform but moved onto the fast line just after leaving. This would have to be the way it's done in future. Once I was coming into Elstree on the MML, Thameslink services run 24-hours and it was the middle of the night, the train was a Brighton to Bedford all-stations service and it was running on the fast lines, because no other passenger services were using them (at night the only Thameslink services that run are Bedford to Brighton all-stations, and EMR trains don't run). When we got into the station, the gate across the stairs to the footbridge was open so we could go through.

[@manomaylr]

@@bfapple And I’m saying that’s true, but apart from signaling and OLE the other things are a lot less major

[@mikemasters1208]

The infrastructure isn’t fit for 140mph…. The current geometry isn’t suitable for 125mph in places - hence the lower speeds. The dynamic forces exerted by trains > 125mph would also change the service life of some component’s….

[@Ztbmrc1]

Very interesting! So eventually all line side signals will disappear. That is a shame, but that is the future of railways. But for ETCS you need coverage of GSM-R, also in the underground sections. Now I know from experience that there is already cellphone coverage all over the London Underground network, so that will be no problem. Thanks for offering a good night sleep to produce this video!

I am guessing in the future when the system is countrywide, all locos will need to have it fitted - will be interesting to see how it will be fitted into the entire heritage fleet of locos - steam, diesels and electric. I just hope the cost of fitting such equipment is not so high that it end's up making it not financially viable to keep many of the loco's mainline capable.

[@bfapple]

@@100SteveB that’s a problem with these 60+ year old heritage steamers and diesels. Almost every single vehicle is unique; we can’t make a “one size fits all” design. Expensive.

Hello Geoff! I started watching your videos a few years ago as a way to familiarize myself with transport in the UK. Two UK trips later I still enjoy watching from Florida. Thanks!

[@radagastwiz]

There's a rare upgrade to ETCS happening soon beyond Europe - the regional train operator in Toronto, Canada, GO Transit, is embarking on a massive system upgrade including electrification of numerous lines and their construction consortium (which includes Deutsche Bahn) have indicated signal upgrades to ETCS will be included.

[@stephensaines7100]

GO is actually far from being a unique adopter: [In Europe, with railways using different signalling systems, a train that crosses borders must have equipment for each country. The European Train Control System (ETCS) was devised to solve this problem with a common system. It has spread to countries around the world - including Australia, China, India, Mexico, Saudi Arabia, South Korea and Taiwan - because it offers improved safety, performance and headway times.] - Advanced signalling will allow more frequent GO Train service

[@kaitlyn__L]

That's fascinating, the in-cab displays are just like what Train Simulator shows! And here I thought that was unrealistically easy/hand-hold-y. It totally makes sense how it takes them a while to get used to looking for waypoints on a screen over keeping an eye-out for lights, but also just how much more information it provides so I can see why they prefer it once they've gotten used to it. I remember being annoyed in 2009 that signalling upgrades kept being delayed/cancelled since the 80s, and in a way it sucks that it's taken another 10 years or so to really happen, and will probably not be finished across the UK until 2040 or 2050... who knows if the Pendolinos will even be in service and running at their design limit of 150mph by the time it covers the WCML! But still, it's really good that it's finally happening. We're massively overdue, but this is hugely important for modernising our railways. Speeds can be higher, track rework can be easier, and that should pay itself forward.

[@OntarioTrafficMan]

You doing this Geoff; rather reminds me of a time when I got up at 4/4:30am, to get to Swanwick and ride on the first passenger service over a new section of rail (at the rear of my previous address).

[@MatthewGeier]

If a steam engine (or vintage diesel) is to be mainline-certified, they need to be fitted with the latest train control equipment, be it cab signaling equipment and/or digital train radio systems so it can safely interact with other traffic on the network. The alternative is to cease mainline operations of heritage equipment as closing a mainline to ordinary traffic to allow a special to run just isn't a viable operations method. Closer to my home, all 'heritage' locomotives have to carry a digital train radio. No radio, no mainline running. Fortunately, they developed a 'portable' unit that can be moved from locomotive to locomotive as required. This avoids expensive kit needing to be fitted to a locomotive that may venture onto the mainline only a handful of times a year.

[@bfapple]

Deltics next.

[@MatthewGeier]

@@bfapple Presumably over time as ETCS signalling rolls out over the network, more of the mainline-certified heritage stock will have to be fitted with ETCS equipment to maintain its mainline certification. This is just the beginning..

[@surfie007]

Brisbane, Australia is currently replacing the signalling on all of its lines with the ETCS and has built a new train depot to fit out all the existing rolling stock. This is in conjunction with the rail megaproject currently under construction known as Cross River Rail - Brisbane's first underground rail line.

[@kkparis]

PTC is just a requirements/concepts that the signaling system in a US FRA regulated railroad must have. Whereas ETCS/ERTMS is a interoperable signaling system. In fact, ETCS implementations can be used to satisfy PTC requirements. And PATH uses Siemens CBTC to satisfy their PTC requirements.

Getting to just north of Peterborough on the ECML by 2029/30 doesn't sound too ambitious.

Does ETCS mandate a change to the emergency procedures for the northern city line? I recall reading that these procedures are quite different from other underground railway tunnels.

I thought that was because of how narrow the tunnels were

[@izzieb]

While it's nice to see ETCS/ERTMS finally rolling out to more lines, the Digswell Viaduct (Welwyn) and tunnels around the aforementioned are a bottleneck that will continue to cause issues...

Exactly Andrew. Its not a solve-all situation but it’s the best that can be done (without building HS2 all the way to Leeds… 🤬)

[@andrewreynolds4949]

@@Nooticus I think a more efficient way to solve those specific restrictions would be to double/expand/rebuild those viaducts and tunnels...

[@Nooticus]

@@andrewreynolds4949 it's close to impossible to do that, especially for the digswell viaduct. impossible meaning that the cost would not be worth the increase in capacity. HS2 is a much much better and more cost efficient option actually. the calculations have been done by people who are cleverer than I am!

[@andrewreynolds4949]

@@Nooticus Maybe for the WCML, but I don't really see much benefit for the ECML. I'm not saying upgrading that bottleneck on the ECML is worth its cost, but I don't think HS2 east would be an effective replacement. Far more effective for the ECML would be targeted upgrades like the dive-under project north of Peterborough, and ERTMS moving block implementation. As a side note, the Digswell Viaduct looks less like a problem to me than the constrained area at Welwyn North station. Additional spans can be built alongside the existing structure if that's what's needed. Putting 2 more lines through the station and the cutting/tunnels north of that would require a lot more rebuilding and property acquisition.

The 225 group tell me that there are no plans to fit InterCity 225s with ERTMS, and they will be phased out before the removal of line-side signals.

[@AlexanderBrassington]

Hoping this can mean a higher speed limit on the ECML. The 225s and Hitachi's are capable of 140mph although the 225s will probably be gone by then. Not sure if Grand Central's 180s can do 140mph? They'll probably get Hitachi's by then anyway since every operator seems to be getting them. Shame about the heritage services but sometimes you have to make sacrifices for progress and if they can upgrade Tornado then they might upgrade others

This will also bring the Northern City Line a bit more in line with the rest of the ECML. Currently, the signalling is the same as the Underground used to have: it uses tripcocks and tunnel telephones instead of more modern system. In a previous video from Geoff, they briefly mention all the equipment that is needed just for the NCL and how old it was - the tunnel telephone receivers were even made out of bakelite.

[@fetchstixRHD]

Thought the tunnel telephone wires/system was more about the traction current in the tunnels (the East London Line had them but I believe they were replaced with handsets) As for trainstops though, they seem to have already been removed, with TPWS loops taking their place? (e.g. Moorgate at 12:48, there's a TSS where there would be a fixed trainstop, and looking at the platform, mini-OSS loops where the timed train stops used to be)

[@bfapple]

The Northern City has already been converted to AWS/TPWS. Tripcocks are gone.

The signalling was upgraded last year, trip cocks are long gone thankfully and TPWS and Axle counters are now in place, the tunnel telephone system is still there though!!

The new hertford switch back (Platform 5) from Stevenage station has been ECTS for a few years now even before the new Platform 5 was built last year. This has been in place between Stevenage and the first part of the Hertford Loop line and been subject to testing the past few years. The new Hertford switchback is its own track to Stevenage station thus no longer needing to use the last two miles of the east coast main line. so more traffic can run on the east coast main line.

The question has to be asked why is it taking 7 years to get up to Peterborough? And why no further? York or Doncaster would seem appropriate staging points if the full benefits of increased capacity are to be gained as soon as possible. The technology is well proven so it seems quite a long time to just install standard kit (I'm aware that the signalling system also has to be upgraded but 7 years for 80 odd miles of track seems 'tardy' - or is this Treasury withholding funding?

[@andrewreynolds4949]

This also has to be done while the route is still in service, and all the hundreds of trains involved must receive the signaling system as well

[@barrieshepherd7694]

​@@andrewreynolds4949 7 years is still a long time. If I understand correctly lineside signals will initially remain but controlled from York. The basic Radio Block Centre / ETCS technology can be installed and non ETCS trains can still run - as they will have to as there cannot be a Big Bang "All ETCS" from Monday approach. I understand that train fitout is problematic but fixed ETCS infrastructure is not (these days) rocket science. I don't think that Level 3 is proposed which would , I agree, significantly add to testing time. Maybe I'm reading too much into 7 years and that is the date when all trains will run under ETCS as opposed to the date when ETCS will first be available for use.
