@25kV How does something like this happen in such a critical spot like the #Eurotunnel?
Edit: And would a rigid overhead system be "better"?

Its high time I did another #railwaysexplained thread. Open to suggestions on topic; before you do though, check my existing threads at https://mas.to/@25kV/110644720069392183

A slightly unusual #RailwaysExplained thread today...
HOW IT WORKS - OVERHEAD LINE TEST TRAINS (SLIGHT RETURN)
A while back I did a thread on OLE test trains which you can read here: https://mas.to/@25kV/110895234449246235 More recently, SPL have put together a further iteration of the FrankenTrain™ to test the next stage of Midland Mainline Electrification (MMLE), & today they kindly invited me and a colleague on board to observe high speed testing of the new OLE between Wigston and Kettering North Junction.

That's everything I can think of that's different about mountain railways - have I missed anything? Comment below.
As always, you can find out more about mountain railways and OLE by downloading my book from https://ocs4rail.com/downloads.
You can also buy the physical book here: https://www.thepwi.org/product/overhead-line-electrification-for-railways
Finally, you can read my other #RailwaysExplained threads here: https://mas.to/@25kV/110644720069392183

@25kV Randklev bridge at #Dovrebanen is broken https://www.banenor.no/nyheter-og-aktuelt/nyheter/2023/store-skader-pa-brua-i-ringebu/ and will be for months, which means no electrified lines between southern part of Norway and the midle part.
(Actually, the #Rørosbanen is also closed https://www.banenor.no/nyheter-og-aktuelt/nyheter/2023/rorosbanen-stengt-etter-styrtregn/ so there is no rail at all for the moment)

@25kV Maybe also for other readers, a quick introduction on how the Norwegian railway is electrified for the moment:

On #EuropeDay 🇪🇺 #9May a picture, taken in August 2002, of a very #European locomotive: a dual voltage #DB 🇩🇪 Class 181.2 seen at #Luxembourg 🇱🇺, with an international service composed of #DB #InterRegio cars. These locos were also equipped to work under 25kV AC in #France 🇫🇷.
-
Related to Norske tog giving away to Ukraine the class 92 diesel units that's supposedly no longer used.
I suspect that when #SJ needs more or less all the hybrid Flirt units (class 76) on the #Røros line with the #Dovre line closed, the class 92 are used a bit more than originally planned for the line north of Trondheim to #Steinkjer/ #Stjørdal.

#DB 🇩🇪 dual-voltage electric 181.001 is seen here at a railfan event at #Koblenz #Lützel in May 2006. This loco was built in 1966 and was able to operate under 15kV AC 16 2/3 Hz catenary (in #Germany 🇩🇪) and 25kV 50 Hz AC (parts of #France 🇫🇷 and #Luxembourg 🇱🇺), thus avoiding a locomotive change at the border.

A relatively recent side interest of mine is rail electrification, and I found this a very useful explainer of the way weights, pulleys and droppers are used to keep the contact wire level in overhead electrification:

(At some point, I will get around to finishing @25kV’s excellent book on the subject, available as a free download here: https://ocs4rail.com)

#Bostadsmarknaden i #Sverige är ett skämt. Det vet vi. Särskilt i våra 3 största städer.
Ett exempel:
https://omni.se/lagenhet-for-23-000-i-manaden-ratas-trots-bostadsbrist/a/nyo3vxLåt oss anta att det är 4 sovrum. Det blir alltså 5750kr/sovrum/månad + vatten. För 1 sovrum och delat kök och badrum, om man kan tänka sig inneboende.
Jag har bott i en 5a på 110kvm byggd 1960-tal, totalt ytrenoverad 2019 innan vi flyttade in, hyra 12400kr/mån. inkl. 25kvm uteplats.
Vad får man för #bostadsrätt i Stockholm för 23000/mån?

Britiske Railway Industry Association (RIA) har laget pamflett https://riagb.org.uk/RIA/Newsroom/Publications%20Folder/Rail_Electrification_The_Facts.aspx (via @25kV) som gir en kort oversikt over hvorfor en skal elektrifisere jernbanen. I Norge er elektrisk energi i tillegg normalt sett billigere enn i Storbritannia.

Railfans and railway professionals of Mastodon:
If you want to learn fascinating stuff about overhead line equipment and traction current ⚡ - a field of the railway system I don't know much about - do follow @25kV and make sure not to miss his excellent #RailwaysExplained threads he's gradually bringing to Mastodon: 👇

#networkrail and Peter Hendy should be ashamed of themselves, and the #ORR is in an untenable conflict of interest under Hendy's control.

#Bostadsmarknaden i #Sverige är ett skämt. Det vet vi. Särskilt i våra 3 största städer.
Ett exempel:
https://omni.se/lagenhet-for-23-000-i-manaden-ratas-trots-bostadsbrist/a/nyo3vxLåt oss anta att det är 4 sovrum. Det blir alltså 5750kr/sovrum/månad + vatten. För 1 sovrum och delat kök och badrum, om man kan tänka sig inneboende.
Jag har bott i en 5a på 110kvm byggd 1960-tal, totalt ytrenoverad 2019 innan vi flyttade in, hyra 12400kr/mån. inkl. 25kvm uteplats.
