Ultra High Speed Electric Multiple Units

I think we've now reached the point where this should be turned into a thread, to avoid discussion disrupting other threads:

What is actually available in terms of commercial models for these cutting edge flagship high speed trains?

Can you actually make up a full train? Is the model accurate - if not what are the flaws?

TGV Sud Est:
Anyone do one???

TGV Reseau
Mehano - HO. 4 car pack (first 2 vehicles each end) Looks ok visually but need to confirm if scale length (Is the nose a touch compressed?). Are intermediate vehicles available at all to make up a credible TGV? Mechanism ?? Detailed accuracy?

TGV Lyra :
HO - Hornby/Jouef(new tooling??). Completely unknown quantity. Will enough vehicles be available to make a full train or is this going to be just a head + tail stub. What will be the drive mechanism. Will they get it absolutely spot on or will there be detailed errors?

Thalys
Mehano - HO. 4 car pack (first 2 vehicles each end) Need to confirm if scale length. Are intermediate vehicles available at all to make up a credible TGV? Mechanism ?? Detailed accuracy?

Eurostar
HO - Hornby , ex Lima ,ex Jouef. Anyone know? Is it back in production? What drives it? Are sufficient vehicles made to give some kind of full train? How accurate is it?

OO - Hornby. Previous generation tooling. First 2/last 2 vehicles currently available but not intermediate trailers. 2nd class intermediate trailers previously available. Bar trailer and first class trailers (2 types) not available - conversion etched sides for these available from Hurst Models for conversion of 2nd trailers, if you can get them. Scale length but indicated to have significant detail "issues" (unidentified) by pedromorgan

N - Kato. Seems to be highly regarded and full formations possible

Pendolino (UK)-
OO. Hornby New tooling. Some concerns just voiced elsewhere about the cab window area from early + prototype photos , though this may be a preproduction model . Seemingly not to be fitted with centre motor mechanism , just a motor bogie. DCC Fitted, presumably with Hornby decoder. Sufficient vehicles to be produced for full 9 coach formation. Originally announced as for trainset market
(And vastly better than Dapols effort though that's not saying much. Probably significantly inferior to Bachmann's Voyager)

ICE

ICE3 and the AVE - HO Trix and Maerklin. Sighted at a distance of 2m across the Hamburg Model Wunterwelt looked relatively undetailed but I don't know the prototypes and it was at speed (3-rail ac , so must have been one of these. A reasonable length of train seems to be possible . I doubt scale length is an issue here - the sections are short. Mechanism? Detailed comments?

ICE1, ICE2 and ICE T - HO Fleischmann . ?? All the usual questions . (Can Neil confirm which ICE is featured in his photo?)

ICE diesel unit - HO? Roco. All the usual questions

HST:
Hornby , OO. Both original Hornby tooling (1979) and Lima tooling (c1990) with Hornby. Hornby power cars depict pre 1980 state, being replaced by Lima power cars correct for last 25 years. Mk3s - Hornby late 90s , scale length accurate but not to latest standards of detail. ex Lima TGS now available so accurate fromations finally possible. Used to be pancake motor bogies - will they fit the new little 5pole "Lima replacement" motor bogie used under the 121 , 156, 73 ? No lights . DCC Ready?

Italian high speed trains?

Any other high speed trains?

I suppose if we are being truly international bullet trains come into the frame - Kato in N ??????

Please fill in the gaps.......
