Broadly, what it shows is that actually, in terms of the severe incidents above 30-minute disruptions, that has come down in absolute number of disruptions from seven in 2007 to two in 2011. Obviously, this is prior to the two incidents. In terms of incidents per 100,000 km, that has come down from 0.05 to 0.
03. Part of the reason why it has come down is because we had, in the earlier years, a number of track intrusions. The track intrusions actually disrupted the smooth running of the trains quite a bit. We see a similar pattern of decreasing number of incidents reported and monitored by the LTA, the track intrusions. For incidents that caused greater than 10-minute delay, there is also a decrease from 30 in 2007, it went up to 37 in 2008 and thereafter, it came down – last year, it was 21 until November. And likewise, measured across per 100,000 km, it came down. Where there are slight increases in the trend of disruptions are those that are of five-minute delay – so five to 10 minutes – that has gone up. Absolute numbers – in 2007, it was 213 incidents; and 2011, for the eleven months, it was about 271 incidents. So we are really roughly talking about almost an incident a day for that kind of disruption. And measured against per 100,000 km, it had also gone up from 1.65 to 1.8 – and these are for more than five minutes.
