A railway junction is a place where two railway tracks join. The shape of a junction looks like

  • Y
  • X

Sometimes the trains just cross and keep going straight ahead to their destination. Sometimes they turn onto the other track to reach the planned destination. Moveable portions of track make this possible.

Road JunctionEdit

A Road junction is a place where two roads meet. These are known as 'T' junctions and 'X' junctions.
