- Closing of manned level crossing gates, after approval from district administration.
-
Works that do NOT require the sanction of the CRS include:
- Provision of telephones at manned level crossings.
- Installation of electrical or mechanical lifting barriers, including emergency interlocking, and sliding booms at interlocked level crossing gates.
- Interlocking existing level crossing gates within interlocked station yards using existing signals.
- Installation of track circuits, axle counters, including dual detection.
- Replacement or modification of signaling assets without changing the yard layout or signal interlocking, either in station yards or at level crossings.

### Safety Certificate
- The Engineer-in-charge must submit a safety certificate on the prescribed form before commencing work.
- The Engineer-in-charge must test the new works and ensure the installation was carried out correctly.
- The Engineer-in-charge must be fully satisfied that the work can be opened to the public without endangering the safety of the travelling public or railway employees.
- The Engineer-in-charge must then bring the installation into use by sending a message to the Commissioner of Railway Safety.
- If the work involves multiple departments, the Engineer-in-charge of each department must sign the certificate.
Use of New Types of Locomotives or Rolling Stock
- The use of new types of locomotives or rolling stock introduced by the Central Government requires the approval of the General Manager of the Government railway.
- Railway administrations other than Government railways need to obtain approval from the Central Government through the CRS.
- The General Manager must inform the CRS ten days before any new locomotive or rolling stock is put into service.
Introduction of New Passenger Trains or Changes in Speed
- Railway administrations can introduce new passenger trains or change the speed of existing ones following instructions from the Central Government.
- If the speed of a new passenger train or existing passenger train exceeds 130 km/h, the railway administration must get approval from the Central Government through the CRS.
Appendix
- Annexure 9-A5 is a safety certificate for S&T works related to the implementation of electrification.
- Annexure 9-A6 is a Joint Safety Certificate for New types of locomotives or rolling stock.
General Instructions
- Safety: Indian Railway Act, General Rules & Subsidiary rules, Rules for Opening of a Railway, and the Indian Railway Schedule of Dimensions are all used to ensure the safety of passengers
- Authorization: Any work that alters the running line requires legal authorization before starting or using the work
- Notification: Before any work begins or new traffic instructions are brought into use, the Operating Department needs to be notified
- Approved plans: All work must be done according to approved plans, standard drawings and specifications and should conform to provisions in the signalling manual
- Deviations: Any deviations must be approved by the Principal Chief Signal and Telecommunication Engineer
- Engineer Incharge: The Signal Engineer incharge is responsible for ensuring adequate men and materials are available for any work
New Lines & Electrification
-
Application: The General Manager of the Railway must provide a set of documents to the Commissioner of Railway Safety at least one month before a new line is opened to the public
- These documents are collectively called "Opening Documents"
- The documents include:
- Tabulated details
- Index plan and section of Railway
- Drawings of works
- List of questions and answers
- Certificates
- List of infringements of maximum and minimum dimensions
- Diagram of proposed testing train
- Station working rules
-
Signalling Documents: The following documents pertaining to signalling and interlocking are also required:
- Tabulated details (Form No. VIII of Rules for Opening of a Railway)
- Drawings of works, plans of station yard showing gradients, the layout of tracks and signals and interlocking including Locking and Selection tables/Route Control chart
- List of Questions and Answers
- Station working Rules
- Certificate for introducing or extending electric traction, containing details of maximum value of Traction current
- Commissioner of Railway Safety: Final authorization for opening a line for passenger traffic or beginning electric traction is given by the Commissioner of Railway Safety after an inspection
- Existing Signalling: Any work affecting existing signalling or interlocking for a new line or electrification requires prior sanction from the Commissioner of Railway Safety
Rolling Stock
- New Rolling Stock: A rolling stock with different principal dimension or a different bogie design or new designs of braking system or suspension details is considered new
- Minor changes: Any minor changes to equipment design or change of internal equipment layout on the rolling stock or minor change of axle load or minor change of track loading density or minor change in unsprung mass are not considered new rolling stock, unless they are likely to significantly affect weight distribution, center of gravity or riding behavior of the rolling stock
- Material modification: Any changes in the design of the coach which alters the system of operation and control over the rolling stock, like change in the braking system or change in the principle of traction are considered material modifications in the type and design of the rolling stock
Use of New Types of Locomotives or Rolling Stock
- Government railway: The General Manager of a Government railway can approve the use of locomotives or rolling stock that was already introduced on Indian railways by the Central Government
- Other Railways: Private railways need approval from the Central Government through the Commissioner for using any locomotive or rolling stock already introduced on Indian railway by the Central Government
List of Questions & Answers for Opening Documents
- Signalling & Telecommunication: Questions are designed to confirm that all requirements and recommendations regarding signalling and interlocking are met, as well as the catechism for signalling interlocking installations
Work Execution
- Open Line Inspection: Open Line inspectors and Officers should be involved in new/alteration works to identify any deficiencies before the work is completed
- Maintenance staff presence: Open Line maintenance staff should be present when work is done in existing location boxes
- Cable route plan: Cable route plans are required to be approved before beginning any trenching and cable laying
- Power supply equipment: Power supply equipment needs to be approved by the PCSTE/OL
- Cable insulation test: Open line organization is responsible for carrying out power supply audits and functional tests before executing agencies can begin non-interlocking working
- Wiring diagram alterations: Any alteration done by executing agencies to wiring diagrams must be reported to open line officials for further testing
- Testing: Executing agencies are responsible for performing continuity, wire count, breakdown, and functional tests before offering the installation to the open line for joint testing
- Maintenance staff planning: Sr.DSTE is responsible for coordinating maintenance staff positioning with construction/Project organisation or Rly PSUs
Commissioning of Signalling Installations
- Safety is paramount: The text emphasizes the importance of following the rules and regulations laid down by the Indian Railway Act, General Rules, Subsidiary rules, Rules for opening a railway, and Indian Railway Schedule of Dimensions.
- Notification for Work: Before any signalling work affecting train operations is commenced, all concerned departments must be notified through a circular issued by the Operating Department. This includes information regarding the commencement date, duration, working arrangements during the work, and the opening date.
- Strict Adherence to Plans: All work must conform to the approved plans, standard drawings, and specifications, and must comply with the provisions of the Signal Engineering Manual (SEM). Deviations require prior approval from the Principal Chief Signal and Telecommunication Engineer (PCSTE).
- Responsibilities of the Signal Engineer: The Signal Engineer in charge is responsible for ensuring availability of adequate manpower and materials before commencing any work.
-
Applications for Sanction: Applications for carrying out signalling works listed in Para 9.2.1 and 9.2.2 of the SEM are submitted in a specific format (Form 1606/1) and should be accompanied by the Station Working Rules:
