Recommended Posts

Great pics John. Anyone know what happened to 048??? i could never find it any where then it went abroad i think?

 

58048 & 58023 are on the battlefield line at shackerstone along with at least one other. 58023 has been resurrected but not sure about the others

Is that as steep as it looks?  :O

It's foreshortened a bit by the telephoto but there are places on the LGV Rhin-Rhone and LGV Est which are like switchbacks, but the TGV's are incredibly powerful.

Despite the depth of the cutting, the climb west from Pagny sur Moselle on the LGV Est is still pretty horrendous. 58.040 descends towards Pagny with a short works train Oct 2005 (taken with a 8mm-50mm lens so not sure of actual focal length)

Between Cologne and Frankfurt there is a summit on the ICE line that makes you feel as though you are going over a humped back bridge!

Thats the thing with high speed lines - they are lousy at changing direction and require very broad sweeping curves to cope with the lateral g-forces and keep trains on the rails, BUt changes in the vertical profile can be handled with ease thanks to the powerful electric traction they use giving rise to the 'rollercoaster' appearance.

 

Of course in the early days of railways a high speed was less desirable (or attainable due to the steam locomotive technology of the time) so the effort was put into keeping gradients and changes between them as gentle as possible. Thus we have some pretty twisty main lines that inhibit train performance to this day (Tilt can only compensate so much)

There are several locations in which the Pendolinos on the West Coast are not able to hit 125 even with tilt. In some places the Voyagers have a lower EPS speed compared to the Pendolinos due to the amount of tilt they have.
