784.2.1. TYPES OF TRAIN PATHREQUESTSBeyond the process of Allocating Capacityamongst the various Candidates, train pathscheduling is an essential activity in trafficmanagement, both for Candidates andfor ADIF, of the utmost importance whenconsidering the size of the ADIF ManagedNetwork and the usual complexity of railtransport management. Suitable scheduling intime and form largely means ensuring qualityand coordination for developing traffic, andhaving a positive influence on punctuality,commercial speed and track capacity.Due to the way in which transport needs arecreated, different types of train paths havebeen established on the ADIF ManagedNetwork.When Capacity requests are made in suitabletime and form, the candidate may reserve trainpaths, obtaining suitable quality attributes,preference in traffic control and certainpunctuality commitments made by ADIF. Thesetrain paths are:• Regular Train Paths (SERVITREN)These are those train paths requestedfor a significant operating frequencywithin the Working Timetable (around40 th days). These support trainoperations that go to make up theTransport Plan for each Candidate.The series of regular train paths makeup the Working Timetable.• Occasional Train Paths(TRENDÍA)These train paths are scheduled torespond to the specific demands of RUsand other Candidates who, accordingto their limited operating days andthe short notice of the request (up to24 hours before the requested traindeparture at origin), are not includedin the Transport Plan.When it is not possible for the Candidateto reserve Capacity in suitable time,ADIF has two special train classes(no train path reservation).• Special Train Paths withApplications (Immediate TrainPaths)These train paths are allocated atthe specific request of the RU andother Candidates as a result ofunscheduled transport needs and areusually generated with at least oneday’s notice. Trains running in thesetrain paths shall be exceptional andcaused by justified circumstances.• Special Train Paths withoutApplicationsThese train paths are allocated as aresult of incidents or failure to fulfilscheduled transport conditions by RUsor other Candidates, usually at theinitiative of ADIF.
