Trains Trains Trains (and paper aeroplanes)

So whilst Tom and Jo were relaxing in Brighton, I was chaperoning Barney (top marks for behaviour, but needs to work on his nose-blowing technique) to/from dad and jean's, and was reminded again of how little I know about trains and how fast they go.

So, I'm devoting a few mins this morning to research, and have found these *gems*

- Microsoft Train Simulator (and as it's available on amazon, I'm getting that for his birthday unless bro or jo forbid me)
- Lots more train simulators
- Train Travel News & Passenger Rail Travel Guides for Business Travel by Train & Leisure Rail Travel & Tours
- Even (gulp) trainspotting

but nowhere can I find a simple list of top train speeds for the various locomotives which operate on the UK network, and more widely....
