There was a fellow named Leonardo Boselli who was active for
a while in some English-language rail discussion groups. I
believe that he works at a major Italian university.

His English is very good.

I never met him, but did correspond with him for a while.
We had planned to meet in Austria on one of my Europe trips,
but it didn't work out.

The e-mail I have for him is leo [at] dicea.unifi.it .

He may be able to help you. It's worth a try.

(You can also try to do an Internet search for his name.)

Hope that helps.
