Two passengers tried to raise safety concerns the night before the Potters Bar rail disaster, an inquest has heard.
Seven people died and 76 were injured when a train derailed outside the station in Hertfordshire, UK, on 10 May 2002.
At the inquest, the judge heard evidence that three separate reports were made about the "rough rides" on the northbound approach to Potters Bar station.
All three reports were dismissed with one misinterpreted, another forgotten about and the third ignored, according to Judge Michael Findley Baker QC.
Safety checks were carried out on the line but only on the southbound stretch of the track, according to the Press Association.
The train was en route between Kings Lynn and London when it crashed while travelling at 98mph.
