A train derailment happened after Network Rail failed to effectively detect track faults, accident investigators have found.
Six wagons came off the track at Eastleigh, Hampshire, in January 2020, blocking the line and damaging equipment.
The Rail Accident Investigation Branch (RAIB) said Network Rail needed a strategy to prevent a repeat.
