Trans Megathread for the Week of 2024-10-07 to 2024-10-13 - ETR 600
The ETR 600 is a class of trains built by Alstom, and are used on the routes between Roma-Bolzano and Roma-Trieste. The train tilts, using Pendolino technology, allowing higher speeds to be maintained through corners without causing discomfort to passengers. The trains are operated by Trenitalia, originally under the Frecciargento (Silver Arrow) branding used for trains capable of travelling between 250 km/h and 285 km/h, In 2022 they were rebranded under Frecciarossa (Red Arrow) after the Frecciargento branding was retired.
The ETR 600 has also been adapted for use in China as the China Railway CRH5 Hexie. Initially 60 sets were ordered, of which nine were manufactured by Alstom and 51 by CNR Changchun Railway Vehicles. Since, another 80 sets have been created for a total of 140, operating across China's north from Beijing to Ürümqi.

Boomer alert -
The kids nowadays are young enough to have not grown up with optical media, so you hear a lot about "movie CDs are rotting!!!!" in sloptube comments or whatever. I pretty much took this as a falsehood; burned CD-R/RW discs and DVD + and - R/RW discs do often quit, 'cause of the way the laser has to burn the pits and lands into the dye of the disc or whatever. But pressed discs? Maybe Laserdiscs, but I have CDs from like 1986 that are still in perfect playing shape. A copy of "Decade" with literal holes in the plastic player that still plays and rips perfectly.
Recently though I actually found a disc that might be "rotting", which is a 1997 (or whatever) DVD copy of Interview With The Vampire. The problematic vampire yaoi made me fight to watch it, because the disc doesn't really have any scratches, but the data layer at the outer edge of the disc (where the layer change happens) has little nicks and chunks missing, even though the plastic surrounding it is fine. So my Sony 4K player freaks out when it hits the halfway mark, and skips like five minutes because the data is actually missing. PC drives don't do much better, so like... wow, I wonder if this is a manufacturing defect or genuine rot? Wild though, first pressed disc I've ever bought that had non-scratch issues...
Kids today don't know about HitClipz
Real.....
I really want to see a closeup of what this looks like. Ive had a couple discs where the reflective label comes off, but never have I heard of the data layer being damaged other than scratches... Thats super fascinating
Just kinda looks like the edge is missing, nicks in the edge:
Damn thats fascinating. I want to see a macro shot so bad lol (I saw a video on CD printing a while ago with some very good shots, I love this stuff). Ive always wondered if its possible to repair the reflective label surface, but I know nothing about DL disks
Edit: I think I see what you mean now, there's the two colours one for each layer right?
I don't think you can see the layers? Any colouration is just the disc reflecting my walls, lol. The "layer change" is just the laser changing focus to read a second metal layer of data behind the visible one.
I doubt you'd be able to fix it, best just burning a whole new disc or finding another one lol. Interview with the Racist here is on Bluray anyway :3
Ah I see... The metal layer IS a data layer, thats super interesting!!
Yeah the pits and lands are carved into that, and then the plastic goes on around them. Data layer samminch...
oh fascinating!!
