High-speed routes with more than one operator

Hi everyone, I am conducting an academic research about the liberalization of passenger high-speed rail and currently I am trying to find which countries in Europe have competition, i.e. more than one rail operator, in high-speed rail.

So far what I know:

• Spain has competition in high-speed rail with three companies (Iryo, Ouigo and Renfe)
• In Italy, there is competition in high-speed rail with TrenItalia and Italo
• Within France, the only competition is found in international routes: Barcelona - Lyon (Renfe) and Paris - Lyon - Milano (TrenItalia and SNCF). But for all the other routes, only SNCF.

I wanted to ask if you know which other countries have more than one operator in their high-speed rail network.

Any help will be highly appreciated!🤗
