STATION WORKING RULES (SWRs) AND TEMPORARY WORKING ORDER. (Back to Index) General Rules 5.06, stipulates “(1) In addition to General Rules for Indian Railways and Subsidiary Rules of a Railway each station shall be provided with Station Working Rules, applicable to the station, issued under special instructions. (2) A copy of the Station Working Rules or relevant extract thereof shall be kept at stations, cabins and level crossings concerned. ” SWRs shall be issued in Bi-lingual i.e. in English and Hindi (Devnagri script) form. 1. Object: The object of issuing SWR is to inform all staff concerned with working of trains about the special features of the station to ensure safe train operations at & between stations including level crossings, depending on local conditions. 2. Authority to issue SWRs: i) Under the provisions of GR 5.06, the authority to issue SWRs rests with the Authorised Officer of Railway. The power to issue SWRs has further been delegated to the Sr.DOM/DOM and Sr.DSTE/DSTE jointly for all stations within the Division. ii) SWRs are issued in conformity with the G&SR and can not, in any way supersede them. In case of any conflict, the provisions of G&SR will prevail. 3. SWRs requiring sanction of Commissioner of Railway Safety (CRS): i) At stations where relaxation has been obtained from provisions of General Rules under approved special instructions, the approval of CRS already obtained shall find place in the SWRs. ii) Railway administration must obtain sanction of the CRS, when the SWRs are revised as a result of any work listed in para 1302 of the Indian Railway’s P.Way Manual. iii) Works requiring the sanction of Commissioner of Railway Safety and notice thereof (See Appendix B to Ch XV of G&SRs) iv) SWRs of Special Class Stations 4. Procedure for Preparation of SWR i) The Sr.DSTE/DSTE will prepare/amend the Rule Diagram on the basis of signalling plan/appendices and send the Rule Diagram and also signalling plan/ appendices in case of interlocked station, to the Sr.DOM/DOM for framing Station Working Rules. ii) Since the Rule Diagram has a vital bearing on the preparation of the SWRs, the Sr.DOM/DOM will scrutinise the Rule Diagram and the Signalling Appendices, if any, and have these checked at the site. ii) The Sr.DOM/DOM will arrange for preparation of the Draft Working Rules by the Transportation Inspector in the Standard Format, after which these will be checked and approved by the Sr.DOM/DOM personally. In case of interlocked stations the Draft Working Rules shall be checked and approved by Sr.DSTE/DSTE. Sr.DEE/DEE (TRD) shall also be associated in electrified sections. iii) If there is a ‘D’ (Flag Station) and ‘DK’ (station with siding) between two Block Stations, the SWRs of the Block Stations on either side shall contain a reference to such D/DK class Station (in Appendix ‘F’ of the SWR). In the case of a DK class Station, the special instructions for working the siding shall also be incorporated in the SWRs of the Block Stations situated on either side of the ‘DK’ class Station. A copy of these special instructions along with the Rule Diagram shall be made available at such DK class Stations. iv) LC Gates controlled by the Stations and rules for their working shall be incorporated in Appendix A of SWR. v) The detailed working instructions of Ghat sections shall also be appended on Appendix to the SWRs of adjacent block stations of Ghat section. 5. Responsibility of the Officers signing the SWRs : i) SWRs are the functional rules governing the working of stations,. These need to be prepared with care and attention as any deficiency in these rules can endanger safety ,in which case the officers signing the SWRs shall alsol be held responsible along with other staff for breach of safety rules. ii) It is obligatory that the rule diagram of the ground conditions are compared at site to confirm accuracy of R.D. In absence of officials signing the SWR having verified it personally, the Transportation Inspector and the SE (Signal) will, after having jointly inspected the site shall certify in writing that the actual layout conforms to what is shown in the Rule Diagram and the number of points and signals quoted therein are correct. 6. Reviewing of SWRs: The SWRs should be reviewed once in every five years. In case the review brings out the necessity of carrying out changes, the SWRs should be re-issued. In the event of more than three correction slips having to be issued, the SWRs should be reissued without waiting for the periodical review to be conducted every five years as mentioned above. 7. Method of correcting SWRs: Whenever any addition/amendment is required to be made in the said rules, the entire page/pages duly signed by concerned officers on which the provisions requiring addition/amendment appears should be replaced. The method of pasting correction slips by hand in the SWRs is not permitted. 8. Responsibility of Transportation Inspectors (TI): ii) The Transportation Inspector is responsible to see that SWRs of stations on his section are correct and upto date. He will also be responsible to ensure that the station staff viz. Station Supdt., Station Master, Switchman, Cabinman, Pointsman, Gateman and any other staff who are in any way connected with train passing duties, possess correct knowledge of the Rule Diagram and the SWRs and observe them strictly. iii) Transportation Inspector will also check the SWRs and Rule Diagram and point out irregularities, if any, detected by him. If he finds that certain rules are impracticable thereby forcing the staff to infringe them, he shall immediately bring this matter to the notice of the Sr.DOM/DOM. If he detects any error or omissions which, in any way, affect safe running of trains, he shall take immediate steps at the spot as necessary for safe working of trains and report the matter to the Sr.DOM/DOM concerned for necessary amendment/ modification in the SWRs. 9. Responsibilities of Station Manger/Station master in charge: The Station Superintendent/Station Master on receipt of the SWRs must immediately check to ensure that these conform to the local conditions at their stations. If he finds any discrepancy in the said rules, he shall immediately bring such discrepancies and difficulties to the notice of the Sr.DOM/DOM and Transportation Inspector of the section. The Station Manager in charge shall see that all staff having definite responsibilities in train passing at their stations correctly understand and follow the SWR. 10. Assurance of staff: i) All the staff who are in any way associated with train passing duties, must sign a declaration in the Assurance Register in token of having studied the SWRs, Rule Diagram and other instructions pertaining to their duties and understood the same and that they are in a position to take up duties independently at the Station. In case of illiterate staff, the Station Manager in charge/Yard Master/Assistant Station Master shall personally explain the SWRs, Rule Diagram and their duties and obtain their acknowledgements in the Assurance Register as a token of their having understood the instructions. The SS/YM/SM/ASM shall also certify that the staff concerned has understood the instructions pertaining to their duties. ii) Fresh assurance shall be obtained in the Assurance Register from the staff concerned when –  (a) He joins at the station as a new member, (b) There is any change in the Station Working Rules, (c) He resumes duty at the station after an absence of 15 consecutive days or more. 10.
