I urge any new starters or newly qualified SMTH staff read the report into the 1988 Clapham Rail Disaster and how it easy it can be to unintentionally cause catastrophic damage and multiple fatalities from a simple wiring error.

Many new rules and regulations including the SMTH were brought in following a large scale inquiry. The RAIB have commented on several occasions that the lessons learned from Clapham are slowly being forgotten.....

"Events at Waterloo... suggest that some in the railway industry are forgetting the lessons learnt from the 1988 Clapham Junction accident.

"The RAIB is concerned that the need for rigorous application is being forgotten as people with personal knowledge of this tragedy retire or move away from front-line jobs.

"This deep-seated, tacit knowledge is part of the corporate memory vital to achieve safety.

"Loss of this type of knowledge as previous generations leave the industry is a risk which must be addressed by organisations committed to achieving high levels of safety."
