Curve Radius Data

[Peter0124]

Hi, is anyone able to share with me a list of curves on the UK network in order of smallest radius? I want to know all the curves under 400 metre radius in particular and the locations of them.

Thanks!

There have been two or three threads about this in recent years, with lots of people eager to post the locations of their favourite candidates for the title of tightest curve, but with a noticeable absence of data on actual radii.

I hope you'll be luckier this time but am not holding my breath.

I'll put it this way - I used to work for Network Rail, and I never managed to get that data out of anybody!

That would be too much data to share.
List would be massive.
If you work on the railway you would need to go to the national team. If not then it will not be easy.
It is easy for lines covered by a TRV, for lines not (where tighter curves will be common) it wouldn’t be easy.
