Railway turnouts are a critical railway infrastructure with a unique complex geometry. As a consequence,
they induce a diverse nature of risk during railway operation. A large number of accidents, collision and
derailment in particular, occur on or near railway turnouts. Not only do the accidents result in operational
downtime and financial losses, they may also yield the casualties and, occasionally, the loss of life. As a
result of such complexity, the maintenance burden of turnouts is remarkably high. To reduce the cost,
casualties and faults, a risk-based maintenance strategy for geometry problems of turnouts has been
developed. In addition to the model, the paper deals with various geometry-related failures and assesses
the relationship between the failures and their contributing factors.
