3.2 Interval and intersection times of pattern trainsThe target norms between interval and intersection times between two trains (either passenger orfreight) that run every hour are specific and set at the local technical minimum time rounded to thenearest minute plus 1 minute buffer time. In case of departure and arrival, however, use is made of thetechnical minimum time plus 2 minutes buffer time, rounded to the nearest full minute, as not only canthe departing train be too late, but the arriving train can also be too early.A technical minimum time has not been calculated for each situation. In that case, use must be madeof the norms entered into Donna. Deviation from those norms is only possible in case of compliancewith the rejection norm and the conditions stated in Section 1 of this appendix. 115If the technical minimum interval time is not known, the rules below are applied.Table 1Interval time in minutesActivity 2 nd trainA P S DActivity 1 st trainarrival (A) 3 2 3 n/apassage (P) 3 3 3 2shortstop (S) 4 4 4 3departure (D) 4* 4 4 3* in case of a platform intervalTable 2Intersection time in the same direction in minutesActivity 2 nd trainA P S DActivity 1 st trainarrival (A) 3 2 3 1passage (P) 3 3 3 2short stop (S) 3 3 3 2departure (D) 4 3 3 2115The exceptions to this rule are stated in Sections 2.4 and 3.5 of this Appendix.appendix 22 Timetable drafting normsNetwork Statement 2014 Combined Network - version 1.0 dated 9 January 2013 page 171
