The Schedule 8 values are net of compensation payments due from train and freight operating companies. The net payment agreed with individual operators is arrived at through a process of attribution of delays where many factors are taken into consideration and compensation amounts are incurred both ways.
Network Rail does not receive compensation payments under schedule 4.
