Difficulty: Easy
Correct Answer: Level crossing
Explanation:
Introduction / Context:
Safe interface between rail and road systems is critical. The terminology for such interfaces distinguishes at-grade intersections from grade-separated structures, guiding selection of protection systems and traffic control devices.
Given Data / Assumptions:
Concept / Approach:
An at-grade intersection between rail and road is called a level crossing. It is distinct from inter-rail connections (crossovers) and multi-track rail junctions, and from road-only intersections.
Step-by-Step Solution:
Verification / Alternative check:
Standards specify level crossing types (manned/unmanned, protected/unprotected) and safety provisions (gates, signals, interlocking).
Why Other Options Are Wrong:
Cross over joins two rail tracks; railway junction is rail–rail intersection; road junction is road–road; “None” is not applicable.
Common Pitfalls:
Confusing level crossings with overbridges/underpasses (grade separated); misusing “cross over” which is wholly within rail domain.
Final Answer:
Level crossing
