London Underground's performance statistics are based on 4-week periods, rather than calendar months. The most recent periods for which results are available are periods 8, 9 and 10. The number of signal failures on the Northern line for these periods are as follows:

Period 8: 20 failures Period 9: 34 failures Period 10: 21 failures
