The control organization of Indian Railways is the nerve centre of train operations. It controls the asset management of the Railways, in a dynamic situation, round the clock incessantly moving trains on its entire network. It has come a long way from being an exclusively telephone based system emerging in the form of an Information Technology enabled organization.This basic structure of Operating control on Indian Railways exists at the Divisional Level, which has also been extended to Area control levels. In addition, Central Control office is situated in the headquarters office and one at Railway Board.

Objectives of the control organization:

1. To ensure Punctuality of the mail / express and passenger trains.
2. To ensure maximum utilization of the rolling stock
3. To ensure maximum utilization of the section capacity
4. To increase the speed of goods trains.
5. Maximum utilization of the train crew.

Traffic control is divided into two units at the HQ level for easing up its objectives:

a. Central control, and
b. Emergency control

Responsibility of traffic operation through out the zonal Railway lies with COM assisted by CPTM, CFTM. The COM advices all divisions regarding traffic and ensure that the objectives are fulfilled as per policy guidelines and planning.

Control organization at the Divisional level

The Control Organisation is one of the Principal Means by which the essential Coordination is obtained in Railway Operation. It is from where, the planning activities of day to day working are done and the orders are issued to the stations and yards for execution.

It can be compared to the brain of human. Normally the Divisional Control Office is located in the Divisional Head Quarters and connected to the station and yards through various communication systems. If the size of the division is large and controlling becomes difficult a sub control office may also be provided at a convenient location.

The area spread of a division is divided into control sections having a given number of stations. A section is generally of the range of 50 to 150 km stretch and the trains are controlled in the section by the Section Controller. The two-way telephone system, also called an omnibus circuit which permits all stations to have
direct communication with section controller, who is responsible for train regulation in his area. The section controller can speak to all stations at the same time or to one station selectively, using individual numbers/buttons. Movement of train is plotted on time distance graph to record their actual progress, these records, called control charts, can be analyzed later.

Sr.DOM has the administrative control of the Divisional Control Office. CHC is the head of the control organisation. For easy and effective controlling, the entire division is divided into various sections and a well knit communication is provided for monitoring minute to minute activities at stations and yards. CHC (In-charge) is assisted by –
Dy. Chief Controller Goods/Mainline
Dy. Chief Controller Coaching
Dy. Chief Controller Stock
Section Controllers
Chief Trains Clerk
Head Trains Clerk
Trains Clerks

The Chief controller being the head of the control organisation is assisted byDy.Chief controller in Freight and Passenger train operations. Dy. CHC looks after the Traffic Control who will guide and assist the SCORs. All technical disciplines involved in train movement have are representative in the control office to provide the required support from his department. These would include-

Chief Diesel Power Controller
Chief Traction Loco Controller
Chief Traction Power Controller
T X R Controller
Commercial Controller
Engineering Controller
Signal & Telecommunication Controller
Security Controller
Crew Controller
ETL Controller
F O I S In-charge

The entire organization works round the clock, all days of the year without any interruption to monitor actual movement of trains on the entire rail network. The detailed organization of the control selected and duties assigned to employees depends on the demands of the transport task appropriate to each grade of employee or to diversity in the transport task. The Chief Controller is the head of Divisional Control Organization.
