Terminals are supposed to operate in open-access mode, but indeed that's a conflict potential, too. In particular in Poland, where new entrants are accusing incumbent PKP of blocking them by demanding unreasonably long buffer times and high charges for the use of their terminals.

An open access operator could also handle wagonload traffic, and there are examples on branchlines and industrial connections abandoned by the freight branch of the incumbent, but of course these aren't much profitable (nor are they an example of competition).
