There are so many places in the U. S. where mainlines cross at-grade that it never occurred to me that the UK had practically done away with them. They do create bottlenecks, and even the best maintained ones require trains to drastically reduce speed before crossing them, and require "diamond" replacement on a regular basis.
Drive the Nottingham - Lincoln line regularly, including yesterday. I've had signal reversions in both directions over the years - terrifying experience as initially you're not quite sure why and have visions of an east coast service bearing down on you at 100 mph...
I had to look up what a “signal reversion” means - learned a lot! Thank you for educating me on this. It had never occurred to me that this could happen. Must be quite nerve-wracking.
I'm surprised that the speed limit for that section of the ECML is still 100mph despite the nature of the flat crossing. I guess in this case it's a food thing that our passenger trains aren't the heaviest in the world since they can decelerate relatively quickly in case of scenarios like a signal reversion.
@@nathanw9770 I think the 100mph is a local speed limit specially for that crossing. Elsewhere line speed is apparently 125mph. There was an collision on that crossing, in 1852.
Wow..... a wonderful view of a unique crossing. Its nigh on impossible to get close to on foot to see trains passing over this. Your view here is just fantastic !!
Nearly 60 years ago, the flat diamond crossing between the ECML & the Sheffield-Lincoln line art Retford, c. 18 miles north of this location, was removed when the "dive-under" was built. I think that eventually a flyover will be built at Newark to take the Nottingham-Lincoln line over the ECML. I believe it's technically feasible, but very expensive. But if the ECML is ever to have 150+ mph trains, grade separation of these two important lines will be essential.
Could they build a bridge for passenger trains, which could climb a much steeper grade, to cross over the ECML. That would at least reduce the number of trains using the flat crossing.
The road bridge next to the crossing was designed to be expanded for a rail bridge. It won’t happen now because the grades on Newark castle station side would be too steep.
@@tonyshield5368 we have a government that hates the railway any big changes at Newark will not happen under them. Network rail have just renewed the flat crossing ( I drove the first engineering train over it after completion!) so they have no appetite for major changes.
I remember doing my brake handling hours from Ipswich depot and my instructor pointed this crossing out at the time. I remember thinking how cool it was then.
I’ve been over that crossing several times on the ECML & even though it’s been recently renewed it still jolts the train as it passes over it. We always wait for that jolt because we know that the train will soon slow for our stop at Northgate.
Great footage! This crossing reminds me of the former highly complex array of diamond crossings at the north end of Newcastle station - now much simplified to just a few points/switches
I still recall having a pee while going through there Northbound at line speed (100mph?) on an HST - nearly had a bit of an accident! This was before it was renewed and I got thrown around the loo quite a bit.
All the speeds at Porthmadog are much slower than they are here too. The WHR drivers can literally stop to look for trains crossing their path. I wonder what the failsafe is on the NR crossing?
@@mikeuk4130NR is the main carrier. So FWHR trains have to phone NR regional Centre in Machynlleth for permission to cross ( manual system) or the ERTMS automatic system decides if Welsh Highland can cross. In either case, NR signals will be set to stop.
Wow. Here in these United States we call these "diamonds" and they are EVERYWHERE. So much so we have made a science of them; most recently the introduction of the two-speed diamond wherein one line carries the tread of the wheel and the other the point of the flange. Our diamonds are not going away anytime soon...Diamonds are Forever?
In the UK railways are primarily for passengers so avoiding the speed restrictions and bumps of diamonds is the priority and bridges are built to avoid them. In the US rail is primarily for freight so speed and bumps are less of a concern and avoiding the gradient necessary to pass one line over the other is the priority. Also the cost of course. Diamonds are much cheaper.
Looks like they could build a flyover for the East - West non electrified section parallel to the road. For example the Durnsford Road flyover at Wimbledon is not that long and has a 60mph line speed if I remember correctly (we rarely used it as mainline services). The curve connection would have to start further back though. I hope they do do the old standard Double blocking for the signalling there? Saying that, we had a Disastro that slid past two red signals in one leaf fall season. Wheels had stopped turning as it slid and the WSP assumed the train was stationary.
Until the Nottingham-Matlock services were re-instated recently the crossing used to cause me untold problems getting from Attenborough to Derby for onward connections as the Grimsby/Lincoln-Leicester services were frequently delayed waiting a path over the ECML, this often resulted in a missed connection at East Midlands Parkway, fortunately it's better now. Another flat crossing occurs at Porthmadog between the Cambrian Coast line and the narrow gauge Welsh Highland Railway.
Recognised it immediately, but strangely I travelled over that several times weekly on both lines for years and it never occurred to me it was a flat crossing! D’uh. Did wonder about all those bumps though 😂
Every single member of Network Rail staff who has completed a Controller of Site Safety recertification knows this area well, as it is used for setting up a theoretical site of work.
The big problem with grade separating this junction is it's bound on 3 sides by major road bridges and 2 sides by the river. There's very little room to raise or lower the alignments in any of those directions, so it would require extensive reconstruction of a lot of the area.
The scheme was to put a wide embankment in when the Newark Western Bypass was built just for the Midland line but the bean counters got their mitts on it However, another reason might have been loads more freight on the Midland in those days
To build flyover is very possible , only major huddle is a46 bridge to the west before Newark castle would have to risen to get gradient to all the heavier freight services to continue to use them Nottingham Lincoln line. There are plans underway to rebuild a46 in that area so hopefully they do pre works to enable a fly over to be build at some stage. But will be a sad day to see Newark flat crossing removed
@@riggermortiss69 I think when they last looked at it they thought they could fit a decent gradient to the west but not to the east. There's a lot of bridges on all sides. Edit: Oops, I had east and west swapped. It was the western side where they had the gradient issues
When one looks at the grade separations of several lines in Melbourne, it is hard to imagine it would be too difficult to do it here for the Nottingham - Lincoln line, there is at least 1 km to the east, and yes to the west the next crossing of the A45 is in the way, but elevating further west before the next A46 bridge would eliminate another level crossing (Great north Road) and several minor level crossings too! This should also be a point where electrification should reach from Nottingham giving a power line connection for Midlands lines.
There was one at Murrow in Cambridgeshire where the MGNJR crossed the GE / GNJR. 2 bad collisions during its life. MGN closed in 1959. GE / GN closed in 1981.
There's more than enough room to build a flyover on the Nottingham-Lincoln line, essentially replicating the A46. Modern trains can easily handle what would be quite a steep approach grade. It's a cost effectiveness decision to keep this.
The A46 Newark Bypass needs a massive upgrade and to be dual carriageway to handle more traffic especially when avoiding Newark-on-Trent. But this flat junction to the north of Newark Northgate and east of Newark Castle stations is a proper landmark in history of how it was built.
I note you say Main line but the public in Wales call the Cambrian cost railway the main line (and considering they just spent a shed load of cash on it i do to) the have a flat crossing where the Welsh Highland crosses to get access to The Ffestiniog railway.near Porthmadog Railway station.
If I heard it correctly the original trackbed was the Nottingham to Lincoln line put there in the 1860’s, when they came to lay the trackbed for the ECML some years later neither company would compromise on the layout so we got a flat crossing.
Grade separation was looked at time proposed £1Billion upgrade to ECML as was adding extra viaduct at Welyln to remove bottlenecks. At Newark 2 options to build a flyover run parrell with A46 bypass over the river & ECML remove the flat crossing, trains have reduce from 125mph to 100 pass through Newark before acceleration again. Someone made comments about 150 speed simply impractical what need think about running at high speed geography of line. Newark very heavy built up area not feasible run trains higher than 115mph through Newark. The other option in conjunction provided flyover install a south to West single lead junction to allow trains need to stop at Newark chance do so. Flat crossing is heavy maintenance problem amount traffic across it passenger trains on ECML upwards 600 tons pounding rail and feature freight train at 75mph usually 2,500 tons lot of tonnage those diamonds are taking at speed. US has few diamond crossings but not at point trains travelling at 75-100mph over them

Nice to see under the motorway bridge the Gypsy squatter camp, modern day gypsy turning it into a permanent site. I just want to point this out for overseas viewers. Note the flat bed truck.
That stretch of the Trent seems very narrow compared to upstream in Nottingham. I see that it splits in two, upstream of this section, then confluences further downstream.
Ideally at the crossing point you have a train station to replace Newark Castle and Newark Northgate. But as others have pointed out the gradient would be difficult, especially when the ECML line is bounded by a road bridge and a river. It would save that horrible walk between the two stations! Raising the Midland line is possible (and could potentially get rid of another level crossing) but not cheap.
And put a station well out of town whose only use would be as an interchange point. At present both Newark stations are fairly close to the town centre.

I was going to ask about this but I'll join your comment instead. (pretty much) All main lines have to be electrified over the next 30 years to phase out Diesel because of climate change. Having an electrified flat crossing seems very problematic, though perhaps it is possible as it would only be a short distance. If they can do it with the rails maybe they can do it with the lines. But if not then there will have to be a grade separation because the lines must be electrified no matter the cost.
Just a thought. There are usually "dead spots" on the overhead cables anyway for when switching between substations. I don't see why they couldn't simply make the few metres of space where the two intersect as dead spots and require the trains to be moving at a minimum speed through it. @@adrianthoroughgood1191

I see no reason why not could east-west line have an overpass. Yes, it would ne expensive, but much safer.
The issue is cost of maintenance, and delay to traffic.
Safety is NOT a problem here.
Drive over it on the a46 for work and under it on the river trent for me hobby
The USA has ( many ) of these ( ! ) ... Hmmmm , a LOT of clatter on an otherwise SMOOTH journey on the modern ( Network Rail ) system .. ( He - He ! ) ..... DAVE™ 🛑
A bit of narration would go a long long way
How far a long way…would you say?
I am no train expert,but this looks like an accident waiting to happen!
its really no more dangerous than any other type of crossing or junction on the railway and fully interlocked signalling, TPWS protected, 3 of the protecting signals are also set back quite a way from the crossing so even if a train did miss a signalin most cases the train would come to a stop before the crossing
But it has happened once before,albeit in the 1800s,but given the history repeats itself every so often I still believe it is an accident waiting to happen.@@james123212
Did you get permission from NR to fly a drone over the railway as this is possibly illegal.
Read the above comments.
In the description "All footage was captured in compliance to Aug-23 CAA UAS guidelines."
Network Rail do not control the airspace above their land so there's nothing they can do about it, it would only be illegal if the operator was controlling it from within railway property without permission.
It's an accident waiting to happen !!
