BBC NewsFewer than 70% of trains run on time, "real" punctuality figures published by Network Rail (NR) suggest.
The statistics are based on services that arrive either early or within 59 seconds of the scheduled time.
The new figures show 69.8% of trains were on time during 2011/12, with only 59.7% of long-distance rail services being within the new limit.
Earlier surveys deemed short-distance trains punctual within five minutes, long-distance ones within 10 minutes.
This is a welcome first step to reporting the true performance of Britain's rail companies, where generous definitions of "on time" and excessive timetable slack paint a picture much rosier than the true one.
