The technique by which the mutual locking between the lever of switches and signals being done by mechanical or electrical device is termed as interlocking.

Interlocking is necessary so as to avoid the possibilities of confusion and danger of pulling wrong signals and ultimately to make smooth movement of train without any conflict to prevent the serious accidents.

“Interlocking is provided to ensure that conflicting movement of signals and points do not take place and train run safely without any trouble”.
