The stated “cost” of running any given passenger service is very susceptible to political interference. That is a general comment, not one specifically aimed at Turkey. So if the aim is to make the infrastructure company “profitable”, then the track access charges will increase, causing fares increases, and making the train operations unprofitable. Conversely, if the imperative is to maintain the level of fares, then the infrastructure company will become unprofitable. The only thing I am certain about is that the existing bloated TCDD Tasimacilik train operation will need to shed vast numbers of its staff in order to become profitable, or to be able to compete with private operators. That could become very unpopular indeed.
