Sacred Cows - Revisiting Fundamental Safety Principles
As a safety engineer for the last 30 years I am used to working within specified limitations. As technology has developed over the last decades, we have managed to improve capacity to a point where these self-imposed industry limitations are now the main constraint on throughput. There has been no serious accident on London Underground since 1975 (Moorgate) and on Network Rail since 2007 (Grayrigg) but will re-assessing these constraints affect the safety of our transport systems and make our journeys less safe? More importantly are we “too safe” at the moment and by revisiting these constraints will we increase (albeit slightly) the risk of an accident, but at the same time reduce the overcrowding and congestion on our roads and thus from a “system” view actually improve safety?
