Hi,
I am railway signalling engineer. I have worked for network rail and other UK project like London underground.
The standard that you mentioned here are CELENEC standard.
One of them is for RAMS.
The topic I can cover is RAMS and railway signalling and the electrical equipment that are used in railway signalling like Track circuits, point machine, relays, interlocking etc.
I can prepare PPT presentation for all these topics for clear understanding.
If it is possible for you specify the topic that you want that will be helpful.
