diamond-crossing

A train passes through a diamond-crossing at a railway junction.

Definition

1. Noun:
   • Railway intersection: A "diamond-crossing" is a specific type of railway track arrangement where two railroad lines cross each other at grade (on the same level), forming a diamond-like shape when viewed from above. This allows trains to pass through the intersection without the need for a switch or turnout.

Usage Examples

• (A physical crossing point where two railway tracks intersect.)
• (A specific track configuration used in railway infrastructure.)
• (A crossing where rails cross at an angle, resembling a diamond.)

Advanced Usage

• "Diamond-crossing in rail signaling": In railway operations, a diamond-crossing is often paired with interlocking signals to control train movements through the intersection.

  • The signalman ensured that only one train could occupy the diamond-crossing at a time to prevent collisions. (A safety-critical feature in rail networks.)

• "Diamond-crossing vs. turnout": Unlike a turnout (which allows trains to switch tracks), a diamond-crossing simply permits two tracks to cross without any switching capability.

  • The diamond-crossing allowed trains to continue straight on their respective lines without stopping. (A passive crossing point, not a switch.)

Variants and Related Words

• Diamond (n): A shape with four equal sides and opposite angles equal, resembling a lozenge or rhombus.

  • The rails formed a diamond pattern at the crossing. (A geometric shape used to describe the crossing's appearance.)

• Crossing (n): A place where two or more paths, roads, or railway lines intersect.

  • The level crossing was upgraded to a diamond-crossing for better efficiency. (A general term for an intersection.)

Synonyms

• Grade crossing: A crossing where two railway lines meet at the same level.
• Railway crossing: A general term for any intersection of railway tracks.

Phrasal Verbs

• Cross over: to move from one side of a track or line to the other.
  • The train must cross over the diamond-crossing carefully to avoid derailing. (To traverse the intersection.)

Related Idioms

• Cross that bridge when you come to it: to deal with a problem only when it arises.
  • We’ll worry about the diamond-crossing maintenance when we need to, but for now, let’s cross that bridge when we come to it. (A metaphorical use of "crossing" to mean handling future issues.)
