TIMETABLE PLANNING RULES
NATIONAL
Section 1 Timetable Planning Process - Permanent Timetable
1.1 Introduction
1.1.2 This section describes the process to be followed to enable agreement between Network Rail and Train Operators of detailed train timings and associated information for publication in the National Rail Timetable (NRT) and Working Timetables.
1.1.3 The timetable planning process for the Permanent Timetable is governed by Part D of the Network Code (last amended in July 2011). In the event of a conflict, the Network Code takes precedence over Track Access Agreements with individual Train Operators and the Engineering Access Statement / Timetable Planning Rules.
1.1.4 The annual timetabling process will be preceded by the development of a Prior Working Timetable which will take account of anticipated major service and infrastructure changes.
1.1.5 The detailed planning process leading up to each passenger timetable change date will consist of a Preliminary Period to determine the Engineering Access Statement and Timetable Planning Rules, followed by a Drafting Period to prepare a Prior Working Timetable, followed by a Preparation Period. Key dates in the planning process are shown in Appendix A. Each stage must be completed by 17.00 hours on the relevant date unless otherwise stated in this document. Further information relating to key dates can be obtained from the Production Schedule published on the Network Rail website at:-

1.1.6 Changes other than at passenger timetable change dates will be handled as dated variants within the permanent timetable or through the short term planning process set out in Section 2 of this National Timetable Planning Rules. Appendix C sets out the conventions governing inclusion of dated variants within the permanent timetable.
1.1.7 Between this, the National Timetable Planning Rules and the individual Route versions, this document should be treated as having primacy.
