In many cases, such as rail yards, many switches can be found in a short section of track, sometimes with switches going both to the right and left (although it is better to keep these separated as much as feasible). Right-hand switches have a diverging path to the right of the straight track, when coming from the point blades, and a left-handed switch has the diverging track leaving to the opposite side. The handedness of the installation is described by the side that the diverging track leaves. Passage through a switch in this direction is known as a trailing-point movement.Ī switch generally has a straight "through" track (such as the main-line) and a diverging route. Unless the switch is locked, a train coming from either of the converging directs will pass through the points onto the narrow end, regardless of the position of the points, as the vehicle's wheels will force the points to move.
it will be directed to one of the two paths, depending on the position of the points) is said to be executing a facing-point movement. A train moving from the narrow end toward the point blades (i.e. These points can be moved laterally into one of two positions to direct a train coming from the point blades toward the straight path or the diverging path. Abt switch used in 1895 built Dresden Funicular Railway (photo of 1985)Ī railroad switch ( AE), turnout, or points ( BE) is a mechanical installation enabling railway trains to be guided from one track to another, such as at a railway junction or where a spur or siding branches off.Ī switch (points) consist of a pair of linked tapering rails, known as points ( switch rails or point blades), lying between the diverging outer rails (the stock rails).
