Some basic UK rail statistics

Basic National Rail Journey Volume Data

The table below shows the following, in column order:
(1) Year, either calendar year or April to March, as indicated;
(2) Number of passenger journeys on national rail network in millions, return journeys counted as two trips, whether journey actually began at a national rail station or not;
(3) That number of journeys in column 2 that was undertaken using a season ticket, in millions; this number is estimated by the LENNON system based on a number of factors and is not the simple multiplier used until the 1980s.
(4) That number of journeys in column 2 that was undertaken using a one-way ticket, in millions;
(5) That number of journeys in column 2 (expressed in millions) that was undertaken wholly on the national rail network, it therefore excludes journeys begun at a London Underground owned station but includes journeys between contiguous national rail stations that happen to have been made in an Underground train (the recent information derives from entry/exit data which has its own peculiar complications and inconsistencies);
(6) The proportion of national rail journeys begun at a London Underground owned station rather than a national rail station.

Note: in adding data for 2009-10 it became apparent that very significant corrections have been made for years back to 2004 and the corrected numbers have now been inserted. It is not unusual for the previous year's information to be updated to more accurate information but more widespread correction is unusual.
