Need for Speed?

Of course it was. Track was built for 140mph usage - especially on the ECML, where these things would run. The T4 bogie is also a component that is designed for 140mph running.

The problem with Britain is the signalling.

Which sections? it cannot surely be all built for 140mph running. Just look at the Morpeth curve!

A fair amount of it could be run at 140mph.

Morpeth is an anomaly. It's not a true representation of the layout of the East Coast.

Just saw that he reached in another test the 568Kmph, the guy has got 20MW of power. (2,5 time more then normal). They now aiming at a speed between 567 and 593 kmph. Well, thats fast!

Note: The fastest train is the MagLev in Japan: 581kmph. done in 2003.

Woah, I sure hope they'll beat the Japanese Maglevs...

I hope this will show the limitations of the wheeled train, as MagLev has full trains doing that sort of speed, but the ordinary trains will be as short as possible, making it impractical.

New Record, the TGV reached the 574.8 km/h

Yes I read that article earlier today. Was about to post it but I was toolate.

The Japanese maglev still holds the absolute railspeed record, but it's not so far off now.

That shot it shows you of it beating it's way across the landscape makes it sound like a jet engine.

tgv just reached a new speed record but 370mph i think

KevinR · Post by **KevinR** » 03 Apr 2007 17:11

356mph. See: http://news.bbc.co.uk/1/hi/world/europe/6521295.stm

Yay, I sure hope they'll be passing the Maglevs.

Maglevs got more speed potential, we are facing the limit of wheeled trains I think.

Here's a nice video of the run, with some frenchmen enjoying the speed:

That video is good. There is an amazing shot just under 1/2 of the way through where the train speeds under a bridge with loads of people on it. That was amazing to look at - you can really feel the speed.

EDIT: Another video - http://www.youtube.com/watch?v=8yszy1wltw8 - Check out the roof shot of the pantograph! Incredible.

Yes this is mainly because there is no phisical connection between train and track, reducing friction to nill (although still some air resistance) Alowing a smaller force for a specific speed.

andysine · Post by **andysine** » 05 Apr 2007 16:27

Yeah, that's true. I always thought that it shouldn't really count as a land speed record though, as it is not actually in contact with the ground.

At the risk of reviving this thread I found this:

I find the projections for the WCML, MML and ECML without new high speed lines to be particularly horrifying.
