It is being reported that NXEA has brought in industry experts to review safety measures after an increase in the number of trains that passed red signals. The number of Signals Passed At Danger (SPADS) had been running at about one per million train miles in 2005 - 2009 but this number dropped to only nine in 2010. However the number is creeping up again this year prompting the safety review.
The vast majority of incidents happened as trains passed the signals by only a few feet, often because of slippery rail conditions. However, every incident is logged and investigated fully.
The Halcrow Group, commissioned by NXEA to carry out a review of procedures, found that "NXEA is implementing a number of initiatives and Halcrow considers these to be setting the benchmark against which industry good practice is measured."
