Poor Track Quality
A tram derailment caused by poor track quality typically results from conditions like severely worn rails, vertical track deflection, or track misalignment.
Inadequate maintenance can allow rails to spread (wide gauge) or track joints to weaken, making the infrastructure unable to safely guide the tram's wheels.
A combination of track defects, mechanical equipment failures, human error, excessive speed, or external obstructions.
