Level crossing where crossing users are protected from, or warned of, the approaching train by devices activated when it is unsafe for users to traverse the crossing. Protection through the use of physical devices includes: - half or full barriers; - gates. Warning through the use of fixed equipment at level crossings includes: - visible devices, such as lights; - audible devices, including bells, horns, klaxons, etc.; - physical devices, such as the vibration of road bumps. Active level crossings are classified as follows. a) Manual. Level crossing where user-side protection or warning is manually activated by a railway employee. b) Automatic with user-side warning. Level crossing where a user-side warning is activated by the approaching train. c) Automatic with user-side protection. Level crossing where user-side protection is activated by the approaching train. This includes a level crossing with both user-side protection and warning. d) Rail-side protected. Level crossing where a signal or other train protection system permits a train to proceed only once the level crossing is fully user-side protected and free from incursion.
