Applications for residual capacity in the running timetable are processed in the order in which they are received by the TVS. This is known as the first-come, first-served principle.
Contract between an applicant and an infrastructure manager. The infrastructure manager guarantees to the applicant capacities for the duration of the order period. In return, the applicant undertakes to order this capacity. Capacities are not precisely defined train paths but a guarantee to receive offers of train paths whose scope is yet to be agreed.
