94reasons to agree to work outsideordinary sessions.In the process of allocating trainpaths, the CM will consider Capacityreserves arising from work scheduledat TOC committees. Candidates shallassume the effects on trains (increasein travelling times, reduced Capacity,etc.) when ADIF communicates this withsufficient notice, for which a minimumperiod of two months is established.The ADIF operating manager may forextraordinary reasons permit the use ofdifferent measurements or periods, withno right to compensation from ADIF.Maintenance bandsMaintenance Bands consist of reserveADIF capacity for ordinary maintenancework on infrastructure and its facilities.3-5 hours a day per line will be scheduledaccording to their characteristics andequipment. On double track, an effort willbe made to leave one track free, exceptwhere ADIF has another measurement, inaccordance with technical reasons. LineCapacity will therefore be restricted inMaintenance Band time when operationsare only ensured on one track. Theplanned intervals for the MaintenanceBands figure on the CM.Extraordinary workAlthough extraordinary work shallpreferably be carried out under the aegisof Maintenance Bands, when a longerinterval, permanent or non permanent,is necessary at specific or temporarytimes, this will be scheduled by the TOCCommittees.When a work interval is required that isdifferent from those in the MaintenanceBands, a record will be made of whichis the extraordinary interval and which isthe normal maintenance interval.Specific, extraordinary work of littleimportance may be directly agreed byADIF with the operators affected, withthe notice considered necessary.4.6.
