This is one reason why the pan on an EMU is near the middle. This can be mitigated to a certain extent by the type of OLE used! Many people have complained about the 'bulky' / 'over engineered' OLE used on the GWML but that is way way more tolerant of multiple pans up than the lightweight BR Mk3 headspan stuff use on the ECML. 1 1 Link to post Share on other sites More sharing options...
Zomboid Posted April 5, 2021 Share Posted April 5, 2021 Though even on the GWML there are reduced speed limits if the two pantographs are not at the outer ends of a set. 2 Link to post Share on other sites More sharing options...
Dr Gerbil-Fritters Posted April 5, 2021 Share Posted April 5, 2021 I don't understand why OHLE seems to cause such confusterucation here in Britain.... the continentals have been using it for years without all the flap doodle we seem to have to go through.

Ours is all "you'll spoil the view" - ugly - bulky... it's OHLE, not going to look like a bunch of flowers is it. Not the best view but: I think the speed has increased to 25mph or something as just outside of the station round the corner there, work ha been on-going to increase the speed. 1 Link to post Share on other sites More sharing options...

Down to cost basically. Our OLE generally runs at lower tensions and wider mast spacings. BR was given the choice of cheap OLE or no OLE by the government, and since cheap OLE was better than no OLE that's what we got. 1 Link to post Share on other sites More sharing options...

That's the sort of picture I've seen. It's difficult to tell for certain but there looks to me to be enough clearance above the train, certainly for the surge arrestor and insulating paint as per Cardiff if not for a conventional solution. There has indeed been some re-modelling just beyond the bridge. Not sure if the track was lowered, if indeed it needed to be. Link to post Share on other sites More sharing options...
Hobby Posted April 6, 2021 Share Posted April 6, 2021 I've a feeling it has, but I think it was for container traffic as they go through Leicester and then down the Nuneaton line where the track has also been lowered under the bridges? Link to post Share on other sites More sharing options...

There is certainly container traffic doing that, but it had been doing so for some years before the re-modelling and I don't think it's particularly gauge restricted. This link is a structure gauge map showing it as W10 in 2016. https://qph.fs.quoracdn.net/main-qimg-52e5892653ddf6641dbf340e68006211 Containers need extra space in the top corners of the gauge, so generally more of a problem for arches than for bridges like this one with horizontal beams.

This is exactly the sort of problem that stupid government made legally impossible. By making European standards statutory, but forgetting that a) our platforms are taller, and b) our trains are shorter, it meant that the legal requirement for minimum wire height next to platforms is impossible to achieve in many locations, especially when there is a low bridge such as this near the station. So in cases like this where in BR days it might just have been possible to work out a solution, it is extremely difficult to come up with something today as you cannot get a derogation against a statutory requirement... 1 Link to post Share on other sites More sharing options...

Not quite that bad now, the industry has got used to the need to do risk assessment and obtain derogation and it doesn't seem to be a problem on recent schemes. However a (safety) risk assessment is always itself a (project) risk, because if it doesn't give the answer you want or it isn't approved by the relevant people then you need to change your design and incur extra cost, quite possibly at a point where it delays completion of the whole scheme.

Shed Posted June 29, 2021 Share Posted June 29, 2021 Is the OLE progressing north much ? 1 Link to post Share on other sites More sharing options...
RMweb Gold geoff Posted June 29, 2021 RMweb Gold Share Posted June 29, 2021 I haven't recently travelled north of Kettering on the main line so I cannot say how much progress there has been. Certainly at the Kettering end the hasn't been much activity bar cutting back some vegetation north of Glendon South where the Manton line branches off. I had heard that work was supposedly taking place from both ends and the main line was closed between Kettering and Leicester this last weekend and also appears to have been closed overnight on various days, if the replacement bus service to Market Harborough late at night and early morning is anything to go by.

Hairy Bear Digital Posted June 30, 2021 Share Posted June 30, 2021 (edited) The line has been shut for relaying of the junction at Kilby bridge. After the initial installing of about 2 dozen structures north of Kettering station, there has been nothing else done that I can see.

RMweb Gold geoff Posted June 30, 2021 RMweb Gold Share Posted June 30, 2021 There has been a fair amount of line side work near Braybrooke. An access has been created off the Dingley road and some land alongside the line (perhaps a former loop) has been cleared of vegetation. There is now quite a good viewing opportunity from the "Plant Man" garden centre car park. Geoff 2 1 Link to post Share on other sites More sharing options...

RMweb Premium jamie92208 Posted July 8, 2021 RMweb Premium Share Posted July 8, 2021 (edited) Once the Midland route to Sheffield is wired then there are several fill in bits that will really start to create s network. Eg, Derbt to Birmingham, Doncaster to Sheffield and then Moorthorpe to Swinton. Cross country would then be able to run from Edinburgh to Bromsgrove under the wires.it will also be interesting to see if 'the old road' from Tapton to Rotherham is included along with Beighton Junction to Sheffield.

Quite a lot of freight uses it, but even if it comes from the MML rather than via Burton, it will be using other non-electrified lines on its journey. So it would remain diesel unless there was some major initiative on freight decarbonisation. Link to post Share on other sites More sharing options...
