French Gradient & Signal Data

I can’t state why but does anyone know where detailed info for gradients, signalling and speed information is available for the following lines in France and Belgium
- Calais Frethun - Lille Europe
- Lille Europe - Brussels Midi (HSL1)
- Lille Flandres and Europe to Paris Nord

thanks in advance

 

Right here. It’s in French of course but you can translate it.

 

Ah yes I have been on this however trying to deceiver what it all means was complicated the map for signals was brilliant the gradient bit though wasn’t very clear even after I translated it all but thanks anyway
