A crossing loop is a place on a single line railway where trains in opposing directions can "cross" each other.
Trains in the same direction can also overtake.
The crossing loop connects to the main track at both ends of the station, though a dead end siding, which is much less convenient, can be used.
Ideally, the loop should be longer than all trains needing to cross at that station.
If one train is too long for the loop it must wait for the opposing train to enter the loop proceeding, wasting a few minutes. Ideally, the shorter train should arrive first and leave second.
If both trains are too long for the loop, time-wasting "sea-sawing" operations are required for the trains to cross.
Platforms
on railway systems that use platforms for passengers to board and disembark trains, especially high level platforms, platforms may provided on both main and loop tracks or just the main track.
