Yep, as Momo said they no longer do this. Originally they lowered the shoes almost immediately after exiting the tunnel. For 9 years, then the first section of the high speed line was opened in 2003 and the switch to 3rd rail was on the outskirts of London, then in 2007 the full high speed line was opened making the shoes redundant, which were then removed in 2008 or 2009.

But the 442s aren't thirty years old. They were built in 1988-1989.

Yeah you're right. The mkIII design is 30 years old, but that particular variant of it was built a bit later.

Third track electrification on the Fréjus transalpine railway, later converted to overhead line: http://www.apmfs.fr/autres.html

I'm assuming the conversion had to due with the Climate?

The third rail was initially considered cheaper, and with easier maintenance during snowfalls in winter. I suppose it was converted because the line obliged to have a dedicated fleet of locomotives adapted to the thrid rail, also forbidding the use og the TGV (used on trains for skiers in winter and on Paris-Milan trains).

Unfortunately the overhead line was energised at 1500 V DC, not 25 kV AC like in other liens in this area. This very low voltage is a problem for freight trains on 33‰ slopes (1 in 30).

Wasn't it the case that the Frèjus line was electrified a long time before the connecting lines because of the tunnel? Hence it makes sense to use a third rail as it was an isolated system for a long time and a third rail was probably easier to install in the tunnel.

The main tunnel (13 km) never had the third rail as since the beginning operated by the Italian raiwlays, it was electrified in 1920 with a three-phase system. The third rail reached Modane in 1930, so this station for some years was both electrified with third rail DC and three-phase AC. The main stations of the French part had overhead lines because of safety reasons, only main line tracks and less important stations had the third rail.

And I'd like to add that that fleet is also most likely the most crashworthy third-rail EMU ever (it's a very well-thought-out, crash-resistant model of carriage).

What a bump - I said that nearly 6 months ago.

If you actually read the thread, and my post, you'll realise that I was addressing flierfy for most of that post, who introduced the Thames (which isn't miscellaneous, but the major river in the area in question, bisecting the major city) when correcting Coccodrillo. I disagreed with flierfy's word 'only', as stations north of the Thames are served by third rail. I did say that Coccodrillo's post was wrong in the way he phrased his claim (though not in so many words) - the only informed and correct thing you've said to me.

My problem with Coccodrillo's post was the word 'whole' (ignoring the grammar of the sentence), when it's patently clear that various lines in Southern England are unelectrified (west of Reading, Basingstoke and Weymouth, Uckfield branch, North Downs line, Gospel Oak-Barking, Great Western beyond Hayes & Harlington and Chiltern line) and various lines are OHLE, mostly coming North and East out of London, though HS1, Paddington-Heathrow and parts of the North and West London Lines are OHLE as well.

PS: no one said that London was 'southern UK' and no one denied it. What was said was 'southern England' and no one denied that either, unless Coccodrillo, or yourself, were defining Southern England to exclude much of East, North and North West London (as well as other areas, like thin strips of land surrounding HS2 and a few other lines, most of the West Country and everything outside London north of the Thames, plus a handful of places near that river) so that the "whole [of] southern England uses third rail" is a true statement.

Isn't that rather a metro than a rail line? There are heeps of metro systems around the globe using a third rail supply.

Neat, Los Teques comes out with a railway, all with the goal of making the line become part of a metro.

Funny, isolating the sleepers/crossties like that, no?

Plus, how come the retaining wall already (opened 2006?!?) looks overly weathered, such that an undertaking of retroffiting it appears to be underway?

I think Southern England suffers a lot with its 3rd rail network. You can't upgrade the electric tension, and it suffers a lot from snow and freezing.
