  • 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
