You are giving an answer about why the urban train operators are afraid. If they are required to have the operating certificate, whomever they rent the tracks from will transfer part of the bill to them. That's what they've feared from the beginning. Anyway, when it comes to certification, you know, they are operating at a rate of 90% on railways run by rail carriers. So the battle is still about fees and costs. If they also manage to raise a problem relating to the certificate, in other words, to make a complaint and ensure that the operator of the urban train is responsible, that would mean that, if the operator is responsible, he would have to pay. Otherwise, the operator will not have the certificate. Right now, what you are telling me, is that, if there is a security-related complaint, the owner of the track would have to do the work.
