1) Junction and terminus :-

Junction - If at least 3 routes are passing from one station, then the station is called a junction. It means that the trains that come into the station must have at least two outgoing train lines. The junction with the highest routes is Mathura i.e. 7. Some other examples are: Six routes are emerging from Salem Junction, five from Vijayawada and 5 from Bareilly Junction etc.

Terminus - When the track or route ends, a station is known as terminus or terminal. The meaning of the terminal itself is the termination. This is the station from where the train does not go further i.e. the train can only enter or leave the station in only one direction. It can also be understood as it is the termination of the track, where each incoming track ends at stop-blocks and does not go any further. The Chhatrapati Shivaji Terminus / Victoria Terminus and Lokmanya Tilak Terminal are the largest terminal stations in the country. The other examples of railway stations are Bandra Terminus, Howrah Terminus, Bhavnagar Terminal, Cochin Harbor Terminus etc.

2) Point and Crossing :-

Point - A pair of tongue and stock rails with the necessary connections and fittings forms a point.

Crossing - A crossing is a device introduced at the junction where two rails cross each other to permit the wheel flange of a railway vehicle to pass from one track to another.
