90This process will initially be carriedout according to estimated Capacityavailable on each line, and dependingon the traffic types figuring on theCM. Once demands have been metaccording to traffic types, those requeststhat have not obtained Capacity mayhave access to residual Capacity forother traffic types, provided this istechnically feasible.When Capacity is allocated to aCandidate other than the RU, the latter shallgive ADIF the details of the RU that is goingto use this Capacity with at least five daysnotice before it is actually used (Art. 14.2ORDEN FOM/897/2005, of 7 th April).• Allocation priority principlesWhen several requests are in a positionto obtain the same train slot, especiallyif the line has been declared to becongested, the priority criteria will beas follows, in a descending order ofpriority:• Priorities that, where appropriate,are established by the Ministry ofPublic Works for the various typesof service on each line.• Service types that take priority onspecialised lines.• Any services declared to be ofpublic interest.• Train paths allocated and actuallyused during the period of theprevious Working Timetable.• International services.• Those requests subject to an existingagreement.• The greatest frequency for which atrain path is requested in a WorkingTimetable.• System efficiency.The CM may modulate strict applicationof these allocation principles in order toensure, as much as possible, accessto all Candidates who have requestedCapacity, especially on lines declaredto be congested.Without prejudice to the applicationof priority criteria, ADIF shall ensurereasonable use is made of trackCapacity. In this respect, some trainsmight, due to their own technicalspecifications, reduce Capacity orimpede operations.This is why ADIF may restrict therunning of some trains on the basis ofsolely technical operating criteria (lackof certain on board equipment, runningtimes not suited to line features, etc.)Furthermore, when a train path isrequested by the Candidate and analternative, less congested route exists,the CM may schedule the train pathat their own initiative along the mostsuitable route, in order to encouragethe greatest Capacity availability fortraffic for which the most congestedroute is technically and economically
