Are there any in-cab signalling methods, ATP, etc. used by IR?

16-07-2019

Some WAP / WAM models have in-cab AWS / ATS (auxiliary warning system, automatic train stop). AWS provides prior in-cab notification of distant or home signals that are displaying danger or 'on'. ATS provides for a locomotive to be brought to a halt in case it overshoots an 'on' signal that it should not have. This has been tried out on the Mughalsarai-Howrah section (ER) but is not in wide use although it was installed in the 1980s. (Pilferage of the track equipment is said to have been one reason for slow adoption by the railways.) Some Mumbai-area suburban EMU routes of WR and CR have ATS and AWS systems (WR had AWS from the 1980s, while CR got it more recently, in 2000). If a signal

What other forms of train working are used on IR other than the block system?
July 16, 2019

Following trains system In this system, trains are worked between two stations by dispatching them one after the other (all in the same direction) at specific intervals (generally at least 15 minutes). The trains are run at specific speeds (less than 25km/h). This ensures that there should only be one train in every 5km stretch in the section

What is Permissive Block (or Absolute Permissive Block) Signalling?
July 16, 2019

Normally, in Absolute Block Signalling, the single-line section between points where sidings or loops are provided must be treated as a single block in order to prevent two trains from entering it at the same time. However, this also reduces track utilization in the case of trains following one another in the same direction. In these cases, a

What is Automatic Block Signalling? (What is the Automatic Block system?)
July 16, 2019

In Automatic Block Signalling (ABS) the signals are automated and operate in conjunction with track circuiting or other means of detecting the presence of a train in a block section. As of March 2003, IR had 3,606 kms of track under the ABS system. When a train enters a block section, the stop signal protecting that block changes automatically

What is Controlled Manual Block?
July 16, 2019

Controlled Manual Block is a system where a manually operated block instrument is used for obtaining the Line Clear permission from the station in advance; however, the clearance of the section must first be verified through track circuiting. The block instrument is connected to the track circuits, and it is not possible for Line Clear to be
