I would like to see the soundproofing increased to reduce the noise from the transmission.Yes since 80 or earlier. Only difference is interior layout Inter City 150 seats with Buffet in 3 car set.
Do they have extra crash protection for the drivers?
I assume you mean the train set VL80? Do you know what the new crash protection actually does? Eg. Its specifications?
Also was anything done for noise reduction that you know of?
Broad brush entire superstructure of drivers cab area has been strengthened, plus the actual driving position appears to have been set back further into the cab.
Also front passenger side doors are said to be back further which has presented safety issues with the external steps no longer being centred with the door . The steps could not be moved account the swing of the bogie now.
Contributors who are VLP drivers would be in the best position to answer your questions however.
