Passing loop

A crossing loop is a place on a single line railway where trains in opposing directions can "cross" each other.

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.

Trains in the same direction can also overtake.
