Obscure Services Abbreviations

Jump to navigationJump to search


This page lists the various abbreviations used in the lists of trains on the Obscure and Sparse passenger services pages.

Individual trains are sometimes marked with a code to draw attention to restricted days or dates of operation, or other important information. These codes are:


  • D Only runs certain dates
  • E Only runs certain dates during summer timetable period only
  • H Only runs certain dates during winter timetable period only

It is important to distinguish between trains which run only on certain dates, but use the obscure route on every day that they operate, and those which do not use an obscure route on every date on which they run. In the latter case the dates on which the train uses the route are normally specified in notes.


(unless otherwise shown, trains run every day of the week)

  • M Monday
  • T Tuesday
  • W Wednesday
  • Th Thursday
  • F Friday
  • S Saturday
  • Su Sunday


  • O only
  • X excepted

Weekdays should be taken to mean Mondays to Saturdays, unless the context suggests otherwise. Public holidays (for which dates are usually shown in the country timetable) generally have a Sunday service or in some cases a modified service. Services may also vary on weekdays immediately before and after public holidays. It is not practicable to include such exceptions in tables and users should check schedules particularly carefully if travelling around public holiday periods.

For some countries, the above abbreviations are replaced by ISO 8601 weekday numbers (https://en.wikipedia.org/wiki/ISO_week_date)
