Suosituksen perustelu
A switch is the single most dangerous element in a railway system. Incorrect work methods used in the maintenance of switches may lead to systematic faults. The expertise of the persons carrying out inspections and adjustments should be ascertained. Additionally, the maintenance provider, the device supplier and the client should cooperate to update the installation and adjustment instructions for Railex and the switch contactors, as well as to ensure that they are unambiguous. The monitoring of switch maintenance should be enhanced. The infrastructure manager should establish an independent body of experts to supervise switch maintenance with regular but random inspections, as well as to inspect the plans relating to switch maintenance and maintenance documentation.
Recommendation
Adjustments of the locking devices and switch contactors located next to them should be inspected regularly and adjusted according to reference values.
