Do diesel fumes impact OHLE performance?

Do diesel fumes/particulates impact the performance of the Overhead lines?

I'm quite an observational person and when stood in a station such as Leeds or York that see a mixture of Electric and Diesel units, I've noticed the overhead lines are covered in a black tar like substance that clearly accumulates from the diesel fumes and this is apparent as it's not present...

I've lost track of the electrification maps.

I don't think so. I personally have been holding fire until we all find out what is in the chancellors budget to be delivered very soon. After that I assume there will be an announcement from the SoS Transport Grant Shapps and then I assume this board will light up and we can all do updates etc.

Not strictly electrification - but all about wires down etc. There have been a few threads

WCML wires down and disruption

OHLE damage

There seems to be a lot of OHLE damage of late and this weekends episode at Wembley cannot be put-down to adverse weather. Is there evidence of more failures of OHLE (maybe due to more 25kv train diagrams) or are they being reported more often (i.e. more likely to be in the mainstream news)?

@GRALISTAIR Most of the links in your OP go to a forum upgrade login page. It looks like the URL formats changed when the forum was upgraded, but it's fairly easy to work out the new URL from the old one.

For example:
Scottish Electrification Thread Updates and Discussion
http://www.railforums.co.uk/showthread.php?t=90420

New URL:
http://www.railforums.co.uk/threads/90420

(the New URL above will automatically forward to a longer version of the URL that includes the thread title, but just replacing showthread.php?t= with threads/ is enough to make the links work)

I am aware of this issue folks reported by @thelem in the post above. I have also alerted @yorkie to see if there is an easy fix.

I have started work on the title page but what is more likely is that I will at least do all the current threads and also do on this page. I still Think this is a valuable resource but with links not clickable it clearly is not as valuable as it was.

Please be patient with me as I work to fix and update.

The proposed Scottish electrification appears to be based on the just "by 2035" but doesn't include the additional proposed by 2045. The difference is that yellow in the 2035 map gets electrified for 2045.

The various bit of electrification with TfW's "Cardiff /Valleys Metro" happening in the next few years also isn't shown.

Hi,

I thought 2045 was way way too far to map and was alternative methods. If people think I should map it, then I don't mind.

Didn't know that was a thing. I'll look into where they want to electrify and map that too. Thanks!


EDIT: I've updated the interactive map. Hopefully it's correct now. I'm in the process of removing Cardiff to Swansea proposal.

A very very good bit of work overall.

I haven't been keeping fully up to date with the Valleys scheme but there may be some gaps in electrification through low height tunnels especially as they are buying multi power source stock for discontinuous electrification.

Scotland - the alternative methods was split into 2 groups:
a) no plans for electrification hence "alternative" is the long term solution.
b) for some of the quieter routes it was for the medium term as the amount of work needed to electrify everything they wanted to do was too great to get done by their initial target date of 2035, hence leaving 3 quieter bit till last. The 3 add on sections with quite long track distances in remote areas for post 2035 (Inverness/Nairn - Inverurie so A-I completely electrified 91 / 76 route miles) ), Inverness - Tain (another 45miles) and Ayr - Girvan (another 20+route miles) all needing extra Grid/DNO supply points (with the power supply work involved there also limiting the pace off work.) These 3 sections also significantly reduce independent energy source requirements and refueling / recharging arrangements (eliminating the requirement in the first, reducing by a third in the later two cases. If the pace of work required for these schemes is the equivalent of ~3-4 years of the pre 2035 pace.
Might it be worth adding the second category in a different shade for Scottish longer term(post 2035)?


It will be interesting to see what the delayed NR report says - that will probably need a few more colours for "maybe" and different time scales.

Thanks!

I did find a document that suggested gaps in the network. I'll have to properly do those on the weekend.

Scotland: I could have a colour to highlight 'Alternatives' or 'Long-term proposed'. I could also have separate colours for cancelled and deferred. The hard part is picking the colour. Open to suggestions.

I'm tempted to put the map on the Speculative forum with an overlay of the schedules so that people can discuss ideas about potential electrification based on historical schedules.

Great piece of work. But may I request an enhancement, please? Quite a few of us struggle with differentiaiting between colours: if it were possible to use fewer colours with different line types - eg dotted, dashed, hollow, filled in, with perpendicular short lines (like sleepers) across lines that would be extremely helpful. That said, it may be that this would be extremely time-consuming, but if it were possible to make it easier for those of us with poor colour vision, that would be really appreciated. Many thanks

Yeah, I think that's possible. I'm next working on the maps this weekend so I will see what I can do.

EDIT: You can on the top-right change the map background. Some people prefer a white background rather than the dark one.
