Moving block is a more advanced system usually associated with ATC (Automatic Train Control). It is not in use anywhere on IR. In moving block systems, a train's position and speed are communicated to control equipment which then computes the appropriate headway to be maintained between and other trains on the same track, and accordingly manipulates the signal aspects and speed controls for the trains on the track. The fine control over the speeds and positions of the trains allows for tight headways and correspondingly high utilization of the track.
