Notes:
1 .The above delay seconds per train movement are based on all delays recorded for attri bu t i o n ,divided by total train move m e n t s .The delay data diffe rs from that used to calculate the 1998
NMS fi g u r e s , which excluded those delays recorded for attri bution of fe wer than three minu t e s .
2. The 1997/98 figures above reflect the actual delay and train movement data and updates the forecasts used in the 1998 NMS.
