Network Rail Calendar: Rail Weeks, Periods and Downloads
🚆 Looking for a Network Rail Calendar?
Paperless Construction provides current and previous-year Rail Calendars, with the latest versions available through our Rail Calendars download library.
The calendar gives rail teams a practical way to align standard calendar dates with Rail Weeks, railway accounting periods and key planning dates. Current downloads are available for 2026 and 2027, alongside previous calendar years for teams reviewing historic programmes or records.
The Office of Rail and Road states that railway accounting uses 13 four-week periods rather than standard calendar months. This makes a dedicated Rail Calendar useful when programmes, reporting cycles and project records need to follow railway periods rather than conventional monthly dates.
This page explains how those periods work, how the calendar can support project planning and where a Rail Calendar sits alongside official Network Rail operational and timetable information.
What Is a Network Rail Calendar?
A Network Rail Calendar, also commonly referred to as a Rail Week Calendar or rail period calendar, is a practical planning reference that helps teams align normal calendar dates with railway reporting periods and Rail Week references.
The Office of Rail and Road confirms that railway accounting operates around four-week periods rather than standard calendar months, with 13 periods in a year.
For contractors, project teams and others working within the rail sector, having those dates visible can make it easier to align programmes, reporting cycles, timesheets and project planning with the railway calendar.
Paperless Construction provides downloadable Rail Calendars as a practical planning resource. They should be used alongside the relevant official Network Rail and Office of Rail and Road information where contractual, operational or safety-critical decisions depend on the dates involved.
Download the Network Rail Calendar for 2026 and 2027
The current Network Rail Calendars should be the starting point for active programmes and forward planning. If your work crosses from one calendar year into another, keeping both the current and next-year calendar available can help maintain continuity through longer lookahead periods.
The dedicated Rail Calendars page contains the complete calendar collection.
2026 Network Rail Calendar
The 2026 Network Rail Calendar is the current calendar for teams working through 2026.
Use it as a quick reference when aligning project dates, reporting periods, commercial records and other programme information with the railway calendar.
2027 Network Rail Calendar
For programmes extending into next year, the 2027 Network Rail Calendar allows teams to plan ahead without waiting for the start of the new calendar year.
Keeping the next calendar available is particularly useful where lookahead programmes, procurement, workforce planning or project milestones cross the year boundary.
2025 Network Rail Calendar
The 2025 Network Rail Calendar remains available for teams reviewing previous programmes, project records and historic reporting periods.
Older Rail Calendars are also retained further down this page for reference.
How Do Network Rail Periods Work?
Railway accounting periods do not follow the normal January to December pattern of calendar months.
The Office of Rail and Road defines a railway accounting period as part of a system where the railway uses four-week accounting periods rather than months. There are 13 periods in a year.
This provides a consistent period structure for railway reporting and analysis. It also explains why a conventional monthly calendar is not always sufficient when a project needs to identify the railway period associated with a particular date.
How Many Network Rail Periods Are There?
There are 13 railway accounting periods in a year.
Each standard accounting period covers four weeks. Instead of simply referring to January, February or March, railway reporting can therefore refer to Period 1, Period 2 and subsequent periods through to Period 13.
For project teams, the important point is consistency. If programme dates, records or reporting requirements are organised around railway periods, everyone working from the same Rail Calendar has a common date reference.
What Rail Week Are We In?
What Rail Week Are We In?
The current Rail Week changes throughout the year according to the railway calendar.
The live Network Rail Calendar board below automatically identifies today's NR Year, railway Period and Rail Week using the current UK date. It also shows the start and end dates of the current Rail Week, giving teams a quick reference without manually searching the calendar.
For forward planning or historic dates, use the relevant year-specific Network Rail Calendar from our Rail Calendars library.
What Is CP7 and How Does It Relate to the Rail Calendar?
Control Period 7, usually shortened to CP7, is Network Rail's current five-year control period.
Network Rail and the Office of Rail and Road confirm that CP7 runs from 1 April 2024 to 31 March 2029.
A control period is different from a railway accounting period. CP7 covers several years, while railway accounting periods divide individual railway years into shorter four-week reporting periods.
That distinction is important when interpreting rail dates.
The 2026 and 2027 Rail Calendars both fall within CP7, but the calendars provide a much more detailed date reference for day-to-day and period-based planning.
Network Rail's CP7 delivery plans cover planned activity, outputs and expenditure associated with operating, maintaining and renewing the mainline railway infrastructure across Great Britain during the control period.
For official CP7 information, refer to Network Rail's current CP7 delivery plans and Office of Rail and Road information.
How Rail Teams Use a Network Rail Calendar
A Rail Calendar is most useful when it remains visible as part of everyday project planning rather than being treated as a document that is downloaded once and forgotten.
Teams can use it when checking how project dates align with railway periods, preparing lookahead programmes or reviewing records from previous reporting periods.
It can also provide a common reference when discussing timesheets, commercial periods, programme dates and upcoming project milestones.
On projects where possession or engineering access dates are involved, the calendar can help provide general date context. It does not replace the formal information governing possession access.
Network Rail states that its Engineering Access Statement sets out arrangements for engineering access to the network, including the location, number, dating and duration of possession access required for inspection, maintenance, renewal and enhancement activities.
That makes the distinction straightforward.
Use the Rail Calendar to understand dates, weeks and periods. Use the relevant Network Rail operational documents for the formal operational requirements governing access and possession arrangements.
Network Rail Calendar vs Timetables and Operational Rules
Several different rail documents contain dates, weeks or timetable information, but they serve different purposes. Understanding those differences helps prevent the Rail Calendar from being used for something it was not designed to replace.
Network Rail Calendar
The Rail Calendar is a practical date and period reference. It helps users connect normal calendar dates with Rail Weeks and railway accounting periods.
For many project teams, this is the document they need when they simply want to understand where a date sits within the railway reporting calendar.
Engineering Access Statement
Network Rail's Engineering Access Statement, or EAS, deals with engineering access to the network.
Network Rail explains that it sets out information including the location, number, dating and duration of possession access and restrictions of use needed for infrastructure inspection, maintenance, renewal and enhancement work.
A general Rail Calendar should therefore not be treated as a replacement for the EAS.
Working Timetable
The Working Timetable, or WTT, serves another purpose.
Network Rail describes the WTT as the rail industry's version of the public national timetable. It includes movements across the rail network, including passenger, freight and empty train movements.
It is a timetable rather than a railway accounting period calendar.
Electronic National Rail Timetable
The electronic National Rail Timetable, or eNRT, is a long-term timetable covering services on the national rail network.
Network Rail publishes the eNRT for passengers and planners, with principal and subsidiary timetable publications during the year.
Again, this serves a different purpose from a Rail Week or railway period calendar.
Network Rail Calendar PDF and Outlook .ics Downloads
Different teams use the calendar in different ways, which is why Paperless Rail Calendars are available in formats suitable for both visual reference and digital calendar use.
The PDF version is useful where the calendar needs to be viewed, printed, displayed in a project office or shared as a fixed reference document.
The .ics format is designed for compatible calendar applications such as Outlook. This allows the calendar information to sit alongside other digital diary and planning information.
For the latest available formats, start from the Rail Calendars download library.
Previous Network Rail Calendars
Historic Rail Calendars remain useful when teams need to review older programmes, records, timesheets or reporting information against the railway period that applied at the time.
Rather than removing previous years, Paperless Construction retains a calendar archive so earlier dates can still be checked when required.

How to Check Network Rail Calendar Information
A Rail Calendar is most valuable when users understand both what it provides and where authoritative information should be checked.
The Office of Rail and Road provides railway period date reference information covering Network Rail control periods, including CP7. ORR also defines the four-week railway accounting period structure and confirms that there are 13 accounting periods in a year.
Network Rail should remain the reference point for its current operational rules, Engineering Access Statement, Timetable Planning Rules, Working Timetable and CP7 delivery information.
Paperless Construction provides this Rail Calendar as a practical planning reference. Where dates affect contractual obligations, possessions, engineering access, train operations or safety-critical activity, verify the relevant requirement against the applicable Network Rail, ORR and project-specific information.
