Railway signaling is the methodology by which the movement of trains are controlled.Warning to the train driver is of significant importance considering that the break distance is long with limited visibility. The trains are guided by the tracks and need guidance through signaling to avoid any collision.Pakistan Railways has a vast network of track, which are guided by obsolete Signaling Systems. They are in the process of up grading their Signaling Systems where Hitech is playing a vital role. This transformation into a Computer Based Interlocking (CBI) Signaling and System will bring technological advancement to Pakistan Railways and  enhance safe train operation with significant financial benefits.
