Module 11: Principles
23/06/2025
This is a complete list of the principles that will be true if a level crossing system has been properly designed.
The checklist
- People who use the level crossing are primed to take on the level crossing user role before reaching the level crossing.
- People can trust the level crossing system and use it to take safe decisions about using the level crossing.
- Level crossing users and people whose work impacts on the level crossing, or is impacted by it, can identify and locate the level crossing.
- People who use the level crossing are provided with enough information to understand how to use it correctly.
- The capability afforded by the level crossing system is available in each instance of use of the level crossing, under all foreseeable operational contexts and ambient conditions.
- Route technical compatibility of rail vehicles with level crossing infrastructure is supported.
- All trains operating on the route stop on the approach to a level crossing that is not available to the train.
- The level crossing system instructs a person to take on and fulfil the task requirements of a level crossing system role where this is necessary to implement the level crossing safety and protection arrangements.
- People who take on a level crossing system role have sufficient competency and experience to carry out the task requirements of the role.
- People who take on a level crossing system role have access to the information and controls necessary to fulfil the task requirements of the role.
- The level crossing system detects all trains that approach the level crossing.
- The level crossing system detects a hazard that could lead to a collision within the level crossing area.
- The level crossing system warns level crossing users of all approaching trains.
- The level crossing system warning provided to level crossing users is standardised and interpretable.
- Level crossing users have enough time to interact with the level crossing system and use the level crossing.
- The level crossing system provides an indication of a failure to a person holding the Supervisor role.
- The level crossing system warns the train driver when a level crossing is not available for passage of the train.
- The train protection system contributes to the mitigation of level crossing collision risk.
- The level crossing system is designed to minimise operational errors and maximise the efficiency of use.
- The level crossing system is configured to militate against misuse.
- Physical separation is maintained between level crossing users and trains.
Note: Not every listed principle is relevant to every level crossing, but it is good practice to consider which principles apply at each location.
