Systems of working:
All trains working between stations shall be worked on one of the following systems, namely :–
(a) The Absolute Block System.
(b) The Automatic Block System,
(c) The Following Trains System,
(d) The Pilot Guard System,
(e) The Train-staff and Ticket System, or
(f) The One Train Only System.
Out of these, The Absolute Block and the Automatic Block Systems are widely used on every railway. The other systems are adopted where the trains are less, the section is small and so cost on signalling system is avoided by adopting simpler systems.
The Absolute Block System is in force in South Eastern Railway in all sections, except the following– Section System of working in force
(i) Tikiapara Kharagpur Automatic Block system. (Double line)
(ii) Tatanagar-Rajkharswan Automatic Block System. (Double line)
(iii) Chandil-Sini Automatic Block System. (Double line)
(iv) Tikiapara-Panskura Single line Automatic Block (Middle line) System.
(v) Tata-Aunlajhari Train staff and ticket System.
(vi) Aunlajhari-Badampahar One train only system
(vii) Aunlajhari-Gorumahisani One train only system
(viii)Bhanjapur-Bangriposi One train only system
(ix) Bankura-Sonamukhi One train only system
(a) The Absolute Block System.
The section between two block stations is called a block section and only one train can be allowed in one block section under normal conditions. The stations are provided with signals so that a train from a station can only start when line clear has been obtained from the block station in advance. This system follows the principle of SPACE GAP.

(b) The Automatic Block System,
When the number of trains increase, a time comes when the section in Absolute Block System starts becoming saturated. Then to handle additional traffic, the The Automatic Block System is adopted. In this system a block section between two block station is split into more sections, and each such sections can accommodate a train. When Automatic Block System is adopted, a increase of 25% of section capacity can be achieved. This system follows the principle of SPACE GAP.

(c) The Following Trains System,
In this system one train follows the another at a time interval of minimum 15 minutes and run with maximum speed of 25 kmph. The driver of each train shall be given a written authority about which train(s) it is following and which train(s) will follow. This system follows the principle of TIME GAP.

(d) The Pilot Guard System,
In this system a PILOT wearing a red dress with badge shall act as an authority to start a train. If two or more trains are to start from a station then earlier trains shall be given with written authority called ticket. The driver shall see that either PILOT is accompanying the train. In case other trains are to run in follow, then the driver shall be given an authority to start the train and PILOT is available at the station. The trains are allowed with time gap of 15 minutes and maximum speed of 25 kmph. This system follows the principle of TIME GAP.

(e) The Train-staff and Ticket System,
This is similar to PILOT GUARD system. The difference is that instead of PILOT GUARD, a TRAIN-STAFF is kept at station. The TRAIN STAFF is a stick with the label and act as an authority. The driver shall ensure that either TRAIN STAFF is given to him. In case other trains are to run in follow, then the driver shall be given an authority to start the train and TRAIN STAFF is available at the station. The trains are allowed with time gap of 15 minutes and maximum speed of 25 kmph. This system follows the principle of TIME GAP.

(f) The One Train Only System.
This system is adopted in branch lines where there is only one train to run in that section. The speed of train is normal speed. Sections where trains are worked on the one
Train only System in the S.E.Rly are (1) Aunlajhori-Gurumahishani, (2)
Aunlajhori-Badampahar(3) Bankura-Sonamukhi(4) Rupsa-Baripada.
